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='HelloIamaveryveryveryverylongstring'; $compressed=gzcompress($str,9);//压缩级别为9 $uncompressed=gzuncompress($compressed); echo$str,"\n"; echo$uncompressed,"\n"; echobase64_encode($compressed),"\n"; echobin2hex($compressed),"\n"; echourlencode($compressed),"\n";
希望本文所述对大家的php程序设计有所帮助。
