gzcompress - Compress a string

SYNOPSIS

       string gzcompress (string  $data, [int  $level = -1], [int  $encoding = ZLIB_ENCODING_DEFLATE])

DESCRIPTION

	This function compresses the given string using the ZLIB data format.

	For details on the ZLIB compression algorithm see the document "ZLIB Compressed Data Format Specification version 3.3" (RFC 1950).

       Note

	       This is not the same as gzip compression, which includes some header data. See gzencode(3) for gzip compression.

PARAMETERS

	      o $data
		- The data to compress.

	      o $level
		- The level of compression. Can be given as 0 for no compression up to 9 for maximum compression.  If -1 is used, the default com-
		pression of the zlib library is used which is 6.

	      o $encoding
		- One of ZLIB_ENCODING_* constants.

RETURN VALUES

	The compressed string or FALSE if an error occurred.

EXAMPLES

       Example #1

	      gzcompress(3) example

	      <?php
	      $compressed = gzcompress('Compress me', 9);
