ob_list_handlers

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
)
