REF, or `r()` is a nicer alternative to PHP's [`print_r`](http://php.net/manual/en/function.print-r.php) / [`var_dump`](http://php.net/manual/en/function.var-dump.php) functions.
## [DEMO](http://dev.digitalnature.eu/php-ref/) ##
## Requirements ##
- (server) PHP 5.3+ (5.4+ displays additional info)
- (client) Any browser, except IE 8 and lower of course
## Installation
Copy folder to `wp-content/mu-plugins`:
## Usage ##
Basic example:
// 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
- `Ctrl` + `X` - toggles display state
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

## 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)
