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

This project is a fork of the original project by digitalnature. A big thank you to him for the work he has done on his project.

DEMO

Or You can see full demo at Full demo

Installation using Composer

Add VarDumper to your composer.json:

{
    "require": {
        "horizom/var-dumper": "^3.1"
    }
}

Now tell composer to download the bundle by running:

composer require horizom/var-dumper

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

Usage

Basic example:

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

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

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

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

dump_text($var);

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

~dump($var);   // html
~dump_text($var);  // text

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

$output = @dump($var);   // html
$output = @dump_text($var);  // text

Keyboard shortcuts (javascript must be enabled):

• X - collapses / expands all levels
• Ctrl + X - toggles display state

To modify the global configuration call \Horizom\VarDumper\VarDumper::config():

// example: initially expand first 3 levels
\Horizom\VarDumper\VarDumper::config('expLvl', 3);

You can also add configuration options in your php.ini file like this:

[varDumper]
varDumper.expLvl = 3
varDumper.maxDepth = 4

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('dump', 'dump_text')	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}/assets/dumper.css'	Local path to a custom stylesheet (HTML only); FALSE means that no CSS is included.
'scriptPath'	'{:dir}/assets/dumper.js'	Local path to a custom javascript (HTML only); FALSE means no javascript (tooltips / toggle / kbd shortcuts require JS)
'showUrls'	FALSE	Gets information about URLs. Setting to false can improve performance (requires showStringMatches to be TRUE)
'timeout'	10	Stop execution after this amount of seconds, forcing an incomplete listing. Applies to all calls
'validHtml'	FALSE	For HTML mode only. Whether to produce W3C-valid HTML (larger code output) or unintelligible, potentially browser-incompatible but much smaller code output

TODOs

• Inherit DocBlock comments from parent or prototype, if missing
• Refactor "bubbles" (for text-mode)
• Correctly indent multi-line strings (text-mode)
• Move separator tokens to ::before and ::after pseudo-elements (html-mode)
