ob_list_handlers - List all output handlers in use

SYNOPSIS

       array ob_list_handlers (void  )

DESCRIPTION

	Lists all output handlers in use.

RETURN VALUES

	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(3), ob_list_handlers(3) will return "default output handler".

EXAMPLES

       Example #1

	      ob_list_handlers(3) 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
	      )

ob_get_status - Get status of output buffers

SYNOPSIS

       array ob_get_status ([bool  $full_status = FALSE])

DESCRIPTION

       ob_get_status(3) returns status information on either the top level output buffer or all active output buffer levels if $full_status is set
       to TRUE.

PARAMETERS

	      o $full_status
		- TRUE to return all active output buffer levels. If FALSE or not set, only the top level output buffer is returned.

RETURN VALUES

	If called without the $full_status parameter or with $full_status = FALSE a simple array with the following elements is returned:

       Array
       (
	   [level] => 2
	   [type] => 0
	   [status] => 0
	   [name] => URL-Rewriter
	   [del] => 1
       )

       Simple ob_get_status(3) results
       Key:level
       Value:Output nesting level
       Key:type
       Value: PHP_OUTPUT_HANDLER_INTERNAL (0) or PHP_OUTPUT_HANDLER_USER (1)
       Key:status
       Value:One of PHP_OUTPUT_HANDLER_START (0), PHP_OUTPUT_HANDLER_CONT (1) or PHP_OUTPUT_HANDLER_END (2)
       Key:name
       Value:Name of active output handler or ' default output handler' if none is set
       Key:del
       Value:Erase-flag as set by ob_start(3)

	If called with $full_status = TRUE an array with one element for each active output buffer level is returned. The output level is used	as
       key of the top level array and each array element itself is another array holding status information on one active output level.

       Array
       (
	   [0] => Array
	       (
		   [chunk_size] => 0
		   [size] => 40960
		   [block_size] => 10240
		   [type] => 1
		   [status] => 0
		   [name] => default output handler
		   [del] => 1
	       )

	   [1] => Array
	       (
		   [chunk_size] => 0
		   [size] => 40960
		   [block_size] => 10240
		   [type] => 0
		   [buffer_size] => 0
		   [status] => 0
		   [name] => URL-Rewriter
		   [del] => 1
	       )

       )

	The full output contains these additional elements:

       Full ob_get_status(3) results
       Key:chunk_size
       Value:Chunk size as set by ob_start(3)
       Key:size
       Value:...
       Key:blocksize
       Value:...
