	Last updated: Thu, 26 Jun 2008

Examples

This example opens a temporary file and writes a test string to it, then it prints out the content of this file twice.

Example #1 Small Zlib Example


<?php



$filename = tempnam('/tmp', 'zlibtest') . '.gz';

echo "<html>\n<head></head>\n<body>\n<pre>\n";

$s = "Only a test, test, test, test, test, test, test, test!\n";



// open file for writing with maximum compression

$zp = gzopen($filename, "w9");



// write string to file

gzwrite($zp, $s);



// close file

gzclose($zp);



// open file for reading

$zp = gzopen($filename, "r");



// read 3 char

echo gzread($zp, 3);



// output until end of the file and close it.

gzpassthru($zp);

gzclose($zp);



echo "\n";



// open file and print content (the 2nd time).

if (readgzfile($filename) != strlen($s)) {

        echo "Error with zlib functions!";

}

unlink($filename);

echo "</pre>\n</body>\n</html>\n";



?>
