# ob_list_handlers

(PHP 4 >= 4.3.0, PHP 5)

ob_list_handlers -- List all output handlers in use

## Description

array ob_list_handlers ( void )

This will return an array with the output handlers in use (if any). If output_buffering is enabled or an anonymous function was used with ob_start(), ob_list_handlers() will return "default output handler".

Example 1. ob_list_handlers() example
`<?php //using output_buffering=On print_r(ob_list_handlers()); ob_end_flush(); ob_start("ob_gzhandler"); print_r(ob_list_handlers()); ob_end_flush(); // anonymous functions ob_start(create_function('$string', 'return $string;')); print_r(ob_list_handlers()); ob_end_flush(); ?>`
The above example will output:
    Array
    (
        [0] => default output handler
    )

    Array
    (
        [0] => ob_gzhandler
    )

    Array
    (
        [0] => default output handler
    )
