Description
array
ob_list_handlers ( void )

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
) |
