PHP 的 Windows 版本已经内置该扩展模块的支持。您无需加载任何附加的扩展库即可使用这些函数。 注: Builtin support for zlib on Windows is available with PHP 4.3.0. 例子 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";?>
to lawyu(雨淋漓) ( ) ：你的例子是用的文件，而我返回的压缩值是放在一个变量里边了，根本没有文件！

是不是把它放到内存中，最后删除这个内存变量？具体的有法子做吗？";$z = gzcompress($s);
