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
PHP;">
$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。
