## Konfiguracja wykonawcza

Na działanie tych funkcji wpływają ustawienia zawarte w pliku php.ini.

Output Control configuration options
Name | Default | Changeable | Changelog
--- | --- | --- | ---
output_buffering | "0" | PHP_INI_PERDIR |
output_handler | NULL | PHP_INI_PERDIR | Available since PHP 4.0.4.
implicit_flush | "0" | PHP_INI_ALL | PHP_INI_PERDIR in PHP <= 4.2.3.

Szczegóły i definicje dotyczące działania PHP_INI_* znajdują się w rozdziale Where a configuration setting may be set.

Oto krótkie wyjaśnienie dyrektyw konfiguracji.

`output_buffering` boolean / integer

  You can enable output buffering for all files by setting this directive to 'On'. If you wish to limit the size of the buffer to a certain size - you can use a maximum number of bytes instead of 'On', as a value for this directive (e.g., output_buffering=4096). As of PHP 4.3.5, this directive is always Off in PHP-CLI.

`output_handler` string

  You can redirect all of the output of your scripts to a function. For example, if you set output_handler to mb_output_handler(), character encoding will be transparently converted to the specified encoding. Setting any output handler automatically turns on output buffering.

  > Informacja: You cannot use both mb_output_handler() with ob_iconv_handler() and you cannot use both ob_gzhandler() and zlib.output_compression.

  > Informacja: Only built-in functions can be used with this directive. For user defined functions, use ob_start().

`implicit_flush` boolean

  `FALSE` by default. Changing this to `TRUE` tells PHP to tell the output layer to flush itself automatically after every output block. This is equivalent to calling the PHP function flush() after each and every call to print() or echo() and each and every HTML block.

  When using PHP within an web environment, turning this option on has serious performance implications and is generally recommended for debugging purposes only. This value defaults to `TRUE` when operating under the CLI SAPI.

  See also ob_implicit_flush().
