FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package php-ref

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

DEMO

Requirements

Installation using Composer

Add REF to your composer.json:

Now tell composer to download the bundle by running:

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):

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

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

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

[ref]
ref.expLvl = 3
ref.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('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' 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
