Конфигурация по време на работа

Поведението на тези функции зависи от настройките в php.ini.

The zlib extension offers the option to transparently compress your pages on-the-fly, if the requesting browser supports this. Therefore there are three options in the configuration file php.ini.

Zlib Configuration Options

Name	Default	Changeable	Changelog
zlib.output_compression	"0"	PHP_INI_ALL	Available since PHP 4.0.5.
zlib.output_compression_level	"-1"	PHP_INI_ALL	Available since PHP 4.3.0.
zlib.output_handler	""	PHP_INI_ALL	Available since PHP 4.3.0.

За по-детайлна информация и дефинициите на константите PHP_INI_*, вижте Директиви на php.ini.

Тук има кратко описание на конфигурационните директиви.

zlib.output_compression boolean/integer

Whether to transparently compress pages. If this option is set to "On" in php.ini or the Apache configuration, pages are compressed if the browser sends an "Accept-Encoding: gzip" or "deflate" header. "Content-Encoding: gzip" (respectively "deflate") and "Vary: Accept-Encoding" headers are added to the output. In runtime, it can be set only before sending any output.

This option also accepts integer values instead of boolean "On"/"Off", using this you can set the output buffer size (default is 4KB).

Забележка: output_handler must be empty if this is set 'On' ! Instead you must use zlib.output_handler.

zlib.output_compression_level integer

Compression level used for transparent output compression.

zlib.output_handler string

You cannot specify additional output handlers if zlib.output_compression is activated here. This setting does the same as output_handler but in a different order.
