ob_list_handlers

(PHP 4 >= 4.3.0, PHP 5)

ob_list_handlers — List all output handlers in use

说明

array ob_list_handlers ( void )

Lists all output handlers in use.

返回值

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".

范例

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();
?>

上例将输出：

Array
(
    [0] => default output handler
)

Array
(
    [0] => ob_gzhandler
)

Array
(
    [0] => default output handler
)
