noop

noop is a really tiny PHP framework for PHP project, based on a really free MVC architecture. The main idea behind this library is being unopinionated, and therefore staying as close as possible of... PHP. There are no PHP extensions in this library, it's just about organization. You know PHP, you'll use PHP.

Download : https://github.com/Amund/Noop

Installation : Unzip, and open the "public" folder in your browser to start coding, or, better, use a virtualhost to expose only this folder. Note that you must activate mod_rewrite module on your Apache server.

Technically, noop is a one file library ("noop.php"), and a one object library ("noop"). All methods in this object are statics, and can be classified this way :

Type	Methods
Core	`config`, `start`, `view` and `pdo`
Registry / Arrays	`get`, `set`, `del`
HTTP response	`output`, `redirect`, `status`
Helpers	`check`, `filter`
Dev tools	`inspect`, `benchmark`

Registry system ^

All datas in noop are stored in a unique multilevel associative array, its registry system. It's globally accessible without polluting global scope, and organized as follow :

config All configuration variables in there
app App related infos, calculated from a request
request Details of the request
controllers Collection of PHP scripts to include, calculated from a request
pdo Collection of PDO instances already created, used as a cache system
benchmark Collection of benchmarks
var Your playground, store anything you want...

During your development, you can inspect this registry at any time with the method inspect.

// Inspect all the registry...
echo noop::inspect();

// ...or a part...
echo noop::inspect( 'config' );

// ...or a part of a part...
echo noop::inspect( 'config/path' );

// ...or... you got it.
echo noop::inspect( 'config/path/controller' );

You can also manage all these keys with the get, set and del methods.

// Store a new key...
noop::set( 'var/foo', 'bar' );

// ...display it...
echo noop::get( 'var/foo' );

// ...and remove it
noop::del( 'var/foo' );

Because it is a simple associative array, you can do any manipulation you want in the registry. But all the root's keys (except var) are internally managed, so use them with caution.

MVC architecture ^

Models ^

There is no direct support for anything related to models in noop. PHP objects are powerful enough !

However, to stay in a noop way, you still have a special location where to store your classes and component, in the folder app/model. A PSR-4 classes autoloader is included, and registered when app start, which check that folder by default. You can modify that default path in the config.php file, check noop source to override it.

If you already have an autoload, you can register it before noop::start() in public/index.php, and disable the internal one with a config path equal to FALSE. You can also include the composer's one, if you use it.

Controllers ^

A controller in noop is a PHP script file, or a collection of script files, located in the controller folder. By default, this folder is app/control, and can be modified in the config.php, by setting a new path for the key path/controller. There is also a default controller, index, that can be overriden the same way, for the key default/controller. I'll explain its usage next.

noop::config( array(
	// ...
	'default'=> array(
		'controller'=> 'homepage'
		// ...
	),
	'path'=> array(
		'controller'=> 'my/new/path'
		// ...
	)
	// ...
) );

Or, since PHP 5.4, with the short syntax.

noop::config( [
	// ...
	'default'=> [ 'controller'=> 'homepage' ],
	'path'=> [ 'controller'=> 'my/new/path' ]
	// ...
] );

Then, here's the fun part.

The controller is called by an URL, as many other MVC framework. But no routing table around, at least not as usual : the filesystem is the routing table.

Consider this controllers folder :

/[noop-path]
	/app
		/control
			/product
				acme.php
			index.php
			product.php

Then, copy/paste this code in index.php and product.php.

echo noop::inspect( 'request' ); // details on how the URL is parsed
echo noop::inspect( 'controllers' ); // What files will be included

Finally, take a breath, and try some URL.

I assume you've configured your web server to expose the public folder to localhost.

http://localhost/
There is no controller, this will use the default controller, index. So, only the file index.php will be included.
http://localhost/contact
There is no contact.php in the controller folder, you'll face a 404 error.
http://localhost/product
There is a product.php file, it will be included.
http://localhost/product/anvil
product.php is always a file, it will be included. product/anvil.php is not, so anvil is not a real controller, it will be considered as a trail (a parameter) for the controller product.
http://localhost/product/acme
product.php is included, and acme.php too.
http://localhost/product/acme/anvil
product.php and acme.php are included, and anvil become a trail.
http://localhost/product/acme/anvil/black/iron
Same as above, but with a long trail. To use this list of parameters in your controller, just explode it.

$trails = explode( '/', noop::get( 'request/trail' ) );
// Array (
//     [0] => anvil
//     [1] => black
//     [2] => iron
// )

If you've got this, you've done the hardest part of noop.

Views ^

There are 2 ways to use controllers/views. The first is a more traditional PHP way, more readable for noop beginners, but more verbose. The second is the pure noop way, for real power users.

Let's start gently.

The rusty PHP way

We want a page to display a product detail, say... hmm... an anvil. From acme. The URL will be

http://localhost/product?id=123

Consider the following controller app/controller/product.php. I let you implement the class Product, in a file app/model/Product.php for example.

// We get the product id from the request
$id = $_GET['id'];

// In a real app, you'll then create a product instance
// $product = new Product();

// Load the product with id 123 from database
// $product->load( $id );

// Get all product properties as array
// $product_data = $product->data();

// to finally obtain :
$product_data = array( 'id'=>123, 'name'=>'Anvil', 'matter'=>'Iron', 'color'=>'Black' )

// We load the "product" view,
// inject product data in it,
// and store the returned string
$product_view = noop::view( 'product', $product_data );

// Prepare the final page
$data = array();
$data['title'] = 'Product details';
$data['content'] = $product_view;

// We get the "page" view,
// inject $data in it (with the product view),
// and echo it, this time
echo noop::view( 'page', $data );

// Then return output to browser.
noop::output( NULL, 'html' );

You'll need a product view app/view/product.php, using the $data variable transmitted:

<div class="product">
	<label>ID</label> <?=$data['id']?><br>
	<label>Name</label> <?=$data['name']?><br>
	<label>Matter</label> <?=$data['matter']?><br>
	<label>Color</label> <?=$data['color']?><br>
</div>

To avoid warnings on non-existent keys in $data, we can also use noop::get on $data, as a filter:

<div class="product">
	<label>ID</label> <?=noop::get( 'id', $data )?><br>
	<label>Name</label> <?=noop::get( 'name', $data )?><br>
	<label>Matter</label> <?=noop::get( 'matter', $data )?><br>
	<label>Color</label> <?=noop::get( 'color', $data )?><br>
</div>

And we also need a reusable standard page view app/view/page.php:

<!DOCTYPE html>
<html>
<head>
	<title><?=noop::get( 'title', $data )?></title>
</head>
<body>

	<h1><?=noop::get( 'title', $data )?></h1>
	
	<?=noop::get( 'content', $data )?>
	
</body>
</html>

With all those files, you can now check http://localhost/product?id=123 in your browser.

The shiny `noop` way

noop has a killer feature : its registry ! You know, this fabulous... simple associative array.

In this array, there is a special place you are encouraged to store in, it's var. It was previously presented as your playground, so let's use it, and save some code. Don't hesitate to add some noop::inspect( 'var' ) to see its content.

And as we rewrite, we will also use the controller trail instead of querystring. URL will become http://localhost/product/123

// Load product
$id = noop::get( 'request/trail' );

// Same as previously, we load product and get properties
// $product = new Product();
// $product->load( $id );
// $product_data = $product->data();
// to obtain :
$product_data = array( 'id'=>123, 'name'=>'Anvil', 'matter'=>'Iron', 'color'=>'Black' )
// But this time, we store them in the `noop` registry
noop::set( 'var/product', $product_data );

// Store the compiled product view in the `noop` registry
noop::set( 'var/product/view', noop::view( 'product' ) );

// Set the page title
noop::set( 'var/title', 'Product details' );

// Then echo page
echo noop::view( 'page' );

We modify the product view, to get data directly from the registry:

<div class="product">
	<label>ID</label> <?=noop::get( 'var/product/id' )?><br>
	<label>Type</label> <?=noop::get( 'var/product/type' )?><br>
	<label>Name</label> <?=noop::get( 'var/product/name' )?><br>
	<label>Matter</label> <?=noop::get( 'var/product/matter' )?><br>
	<label>Color</label> <?=noop::get( 'var/product/color' )?><br>
</div>

And the page view too:

<!DOCTYPE html>
<html>
<head>
	<title><?=noop::get( 'var/title' )?></title>
</head>
<body>

	<h1><?=noop::get( 'var/title' )?></h1>
	
	<?=noop::get( 'var/product/view' )?>
	
</body>
</html>

Choose your path

Obviously, there is no best way, it's just a matter of taste. You can choose a way, or mix them, or whatever. That's what I call unopinionated.

API ^

benchmark( `$name`[, `$action`] ) ^

Set/Get some benchmarks, to trap too long functions, etc... during the development. A benchmark with name "page" is added internally. All benchmarks are also added as HTTP headers ("X-Benchmark-Page: 0.123456").

Parameters

$name Required, String. Name of the benchmark.
$action Optional, Boolean or NULL, default to NULL. TRUE start the benchmark, FALSE stop it, and NULL (or no value) return the timer.

Return

If $action is NULL, return the benchmark value, in seconds.

Example

noop::benchmark( 'mylongloop', TRUE ); // start
//...some code to evaluate...
noop::benchmark( 'mylongloop', FALSE ); // stop

// ...then print
echo noop::benchmark( 'mylongloop' ); // '0.123456', in seconds

// Additionally, you'll find a "X-Benchmark-mylongloop: 0.123456" in HTTP response headers

check( `$reg`, `$var` ) ^

Check if $var match the regexp $reg.

Parameters

$reg Required, String or Array
$var Required, String or Array

Return

Boolean, if $reg and $var are strings
Array of errors, if $reg and $var are arrays

Example

Simple version, with strings

$test = noop::check( '#\d+#', '123' );
var_dump( $test ); // => TRUE

$test = noop::check( '#\d+#', 'my test' );
var_dump( $test ); // => FALSE

Less simple version, with arrays

$reg = array( 'a'=>'#\d+#', 'b'=>'#\w{1,}#' );
$var = array( 'a'=>'123', 'b'=>'is checked', 'c'=>'is not checked' )
$errors = noop::check( $reg, $var );
var_dump( $test ); // => array()

$reg = array( 'a'=>'#\d+#', 'b'=>'#\w{1,}#' );
$var = array( 'a'=>'wrong', 'b'=>'right', 'c'=>'is not checked' )
$errors = noop::check( $reg, $var );
var_dump( $test ); // => array( 'a'=>FALSE )

config( `$config` ) ^

Extend/Override noop configuration registry. You can load different parts of a heavy configuration, configure pathes, manage DB connections, add mime types, switch configuration (dev/prod), add your own app specific configuration variables, etc...

Parameters

$config Required, Array

Example

var_dump( noop::get( 'config' ) );

// Array (
//     [default] => Array (
//         [controller] => index
//         [lang] => en
//         [mime] => html
//     )
// ...

$config = array(
	'default'=>array(
		'controller'=>'default',
		'lang'=>'fr'
	)
);
noop::config( $config );

var_dump( noop::get( 'config' ) );

// Array (
//     [default] => Array (
//         [controller] => default
//         [lang] => fr
//         [mime] => html
//     )
// ...

del( `$path`[, `$array`] ) ^

Delete a key in an array, based on a virtual path to this key.

Parameters

$path Required, String.
$array Optional, Array. If omitted, the noop registry is used.

Return

FALSE if $path was empty
NULL if the key was not found in array
Otherwise, the deleted value is returned

Example

$myarr = array(
	'path'=>array(
		'to'=>array(
			'key'=>'value'
		)
	)
);

noop::del( 'path/to/key', $myarr );

// Array (
//     [path] => Array (
//         [to] => Array
//             (
//             )
//     )
// )

filter( `$src`, `$allowed` ) ^

Perform a filter on an array with a whitelist of keys. Other keys are removed.

Parameters

$src Required, Array. The source array
$allowed Required, Array. The whitelist of keys

Return

A new array, with only withelisted keys

Example

// http://test/?q=42&lang=fr&out=txt&referer=
$request = noop::filter( $_GET, array( 'q', 'lang' ) );

// Array (
//     [q] => 42
//     [lang] => fr
// )

get( `$path`[, `$array`] ) ^

Get a value from an array, based on a virtual $path to its key.

Parameters

$path Required, String.
$array Optional, Array. If omitted, the noop registry is used.

Return

$array, if the path is empty ('') or root ('/')
The key value, if the $path is found
Otherwise, NULL

Example

$myarr = array(
	'path'=>array(
		'to'=>array(
			'key'=>'value'
		)
	)
);

echo noop::get( 'path/to/key', $myarr ); // => 'value'

inspect( [`$path`[, `$arr`]] ) ^

Development tool to inspect variable in a readable way.

Parameters

$path Optional, String. The "virtual" path to the key. Default to ''
$arr Optional, Array. If omitted, the noop registry is used.

Return

Print formatted string representation of the variable if $return is TRUE

Example

// To have a look on current request
echo noop::inspect( 'request' );

output( [`$content`[, `$type`]] ) ^

Stop the current script, and send the HTTP response to the client.

Parameters

$content Optional, String. The response body to send
$type Optional, String. A valid MIME type, or a shortcut ('text', 'html' or 'json')

pdo( `$name` ) ^

Create a named PDO object, based on its configuration. The object is cached at the first call, for further use.

In the config registry, there is a dedicated pdo array to store your collection of connection strings. These string are constructed in the form '[driver],[dsn],[user],[password]'

Example: 'mysql,host=localhost;dbname=db,admin,fZ5GdsV4'

Parameters

$name Required, String

Return

PDO instance

Example

Setup databases connections

noop::config( array(

Then use them anywhere

$stmt = noop::pdo( 'db1' )->query( 'SELECT * FROM table' );

redirect( `$url`[, `$code`] ) ^

Stop the current script, and make an HTTP redirect to url.

Parameters

$url Required, String. The URL to redirect to
$code Optional, Integer. The HTTP redirect code. Default to '302'

Example

// An external URL
noop::redirect( 'http://www.google.com/' );

// or a relative URL
noop::redirect( noop::get( 'app/url' ).'/contact' );

set( `$path`, `$value`[, `$array`] ) ^

Set a value from an array, based on a virtual $path to its key.

Parameters

$path Required, String.
$value Required, Mixed.
$array Optional, Array. If omitted, the noop registry is used.

Return

TRUE

Example

$arr = array();
noop::set( 'first', 'foo', $arr );
noop::set( 'second/key', array( 1, 2, 3 ), $arr );

// Array (
//     [first] => foo
//     [second] => Array (
//         [key] => Array (
//             [0] => 1
//             [1] => 2
//             [2] => 3
//         )
//     )
// )

start() ^

Launch noop app with the current configuration. In the registry, app, request and controllers arrays are populated, and the controllers scripts are included.

All configuration variables must be modified before this method.

After controllers inclusion, there is an implicit call to noop::output().

status( `$code`, `$status`[, `$content`[, `$type`]] ) ^

Stop the current script, and return HTTP response to the client.

Parameters

$code Required, Integer. HTTP response code
$status Required , String. HTTP response status
