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
) |
