php压缩和解压缩字符串的方法

本文实例讲述了php压缩和解压缩字符串的方法。分享给大家供大家参考。具体如下：

下面php代码通过gzcompress和gzuncompress压缩和解压缩字符串，可以设定压缩级别

$str = "Hello I am a very very very very long string";$compressed = gzcompress($str, 9);//压缩级别为9$uncompressed = gzuncompress($compressed);echo $str, "";echo $uncompressed, "";echo base64_encode($compressed), "";echo bin2hex($compressed), "";echo urlencode($compressed), "";

希望本文所述对大家的php程序设计有所帮助。
