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, "\n"; echo $uncompressed, "\n"; echo base64_encode($compressed), "\n"; echo bin2hex($compressed), "\n"; echo urlencode($compressed), "\n";
希望本文所述对大家的php程序设计有所帮助。
