List all output handlers in use
array ob_list_handlers ( void )
Lists all output handlers in use.
Returns:
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".
Examples:
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(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] => Closure::__invoke )
