Fork
----

[](#fork)

This is a fork of digitalnature/php-ref with updates from [Juan Manuel Cabello](https://github.com/fellowgeek/php-ref) to include PHP8 adaptations, modified to use `dd()` like in Laravel Framework.

> REF, or `dd()` 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) / or `r()` itself functions

Demo
----

[](#demo)

[DEMO from `digitalnature/php-ref`](http://dev.digitalnature.eu/php-ref/)

Installation
------------

[](#installation)

Start by [installing composer](https://getcomposer.org/doc/01-basic-usage.md#installation). Next do:

```
$ composer require w3spi5/php-ref-dd

```

Requirements
------------

[](#requirements)

PHP 8.x+

Now tell composer to download the bundle by running:

Composer will install the bundle to the directory `vendor/w3spi5`.

Usage
-----

[](#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
dd(get_declared_classes());

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

```

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

```
ddt($var);

```

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

```
~dd($var);   // html
~ddt($var);  // text

```

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

```
$output = @dd($var);   // html
$output = @ddt($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:

OptionDefaultDescription`'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)License
