ob_list_handlers

(PHP 4 >= 4.3.0, PHP 5)

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

//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] => ob_gzhandler
)

Array
(
[0] => default output handler
)
