REF, or r() is a nicer alternative to PHP's print_r / var_dump functions.

DEMO

Requirements

(server) PHP 5.3+ (5.4+ displays additional info)
(client) Any browser, except IE 8 and lower of course

Installation using Composer

Add REF to your composer.json:

{
    "require": {
        "digitalnature/php-ref": "dev-master"
    }
}

Now tell composer to download the bundle by running:

$ php composer.phar update digitalnature/php-ref

Composer will install the bundle to the directory vendor/digitalnature.

Usage

Basic example:

// include the class (not needed if project runs with Composer because it's auto-loaded)
require '/full/path/to/ref.php';

// display info about defined classes
r(get_declared_classes());

// display info about global variables
r($GLOBALS);

To print in text mode you can use the rt() function instead:

rt($var);

To terminate the script after the info is dumped, prepend the bitwise NOT operator:

~r($var);   // html
~rt($var);  // text

Prepending the error control operator (@) will return the information:

$output = @r($var);   // html
$output = @rt($var);  // text

Keyboard shortcuts (javascript must be enabled):

X - collapses / expands all levels

To modify the global configuration call ref::config():

// example: initially expand first 3 levels
ref::config('expLvl', 3);

Currently available options and their default values:

Option	Default	Description
`'expLvl'`	`1`	Initially expanded levels (for HTML mode only). A negative value will expand all levels
`'maxDepth'`	`6`	Maximum depth (`0` to disable); note that disabling it or setting a high value can produce a 100+ MB page when input involves large data
`'showIteratorContents'`	`FALSE`	Display iterator data (keys and values)
`'showResourceInfo'`	`TRUE`	Display additional information about resources
`'showMethods'`	`TRUE`	Display methods and parameter information on objects
`'showPrivateMembers'`	`FALSE`	Include private properties and methods
`'showStringMatches'`	`TRUE`	Perform and display string matches for dates, files, json strings, serialized data, regex patterns etc. (SLOW)
`'formatters'`	`array()`	Custom/external formatters (as associative array: format => className)
`'shortcutFunc'`	`array('r', 'rt')`	Shortcut functions used to detect the input expression. If they are namespaced, the namespace must be present as well (methods are not supported)
`'stylePath'`	`'{:dir}/ref.css'`	Local path to a custom stylesheet (HTML only); `FALSE` means that no CSS is included.
`'scriptPath'`	`'{:dir}/ref.js'`	Local path to a custom javascript (HTML only); `FALSE` means no javascript (tooltips / toggle / kbd shortcuts require JS)
`'showUrls'`	`TRUE`	Gets information about URLs. Setting to false can improve performance (requires showStringMatches to be TRUE)
