• brotli.output_compression boolean

  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: br" header. "Content-Encoding: br" and "Vary: Accept-Encoding" headers are added to the output. In runtime, it can be set only before sending any output.

• brotli.output_compression_level integer

  Compression level used for transparent output compression. Specify a value between 0 to 11. The default value of -1 uses internally defined values (11).

Available since PHP 5.4.0.

• brotli_compress — Compress a string
• brotli_uncompress — Uncompress a compressed string

string brotli_compress ( string $data [, int $quality = 11, int $mode = -1 ] )

This function compress a string.

• data

  The data to compress.

• quality

  The higher the quality, the slower the compression. (Defaults to 11)

• mode

brotli_compress, brotli_uncompress function alias.

Brotli compression and uncompression are available using the compress.brotli:// stream prefix.

$compressed = brotli_compress('Compresstest'); $uncompressed = brotli_uncompress($compressed); echo $uncompressed;

ini_set('brotli.output_compression', 'On'); // OR // ob_start('ob_brotli_handler'); echo ...;

"Accept-Encoding: br" must be specified.

$data = \Brotli\compress('test'); \Brotli\uncompress($data);

file_put_contents("compress.brotli:///patch/to/data.br", $data); readfile("brotli.brotli:///patch/to/data.br");
