压缩字符串,然后解压缩字符串？

Question

我现在正在使用数十万行字符串.无论如何我可以将字符串压缩为像MD5一样,然后解压缩它？

是的,您可以在PHP(演示)中压缩和解压缩字符串:

$str = 'Hello I am a very very very very long string';
$compressed = gzcompress($str, 9);
$uncompressed = gzuncompress($compressed);

echo $str, "\n";
echo $uncompressed, "\n";
echo base64_encode($compressed), "\n";
echo bin2hex($compressed), "\n";
echo urlencode($compressed), "\n";

但是MD5不是压缩而是散列.
