::(滑稽) 当我们说到压缩，我们可能会想到文件压缩，其实，字符串也是可以压缩的。
PHP提供了 gzcompress() 和gzuncompress() 函数：
$string = “Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc ut elit id mi
ultricies adipiscing. Nulla facilisi. Praesent pulvinar, sapien vel feugiat vestibulum,
nulla dui pretium orci, non ultricies elit lacus quis ante. Lorem ipsum dolor sit amet,
consectetur adipiscing elit. Aliquam pretium ullamcorper urna quis iaculis. Etiam ac
massased turpis tempor luctus. Curabitur sed nibh eu elitmollis congue. Praesent ipsum diam,
consectetur vitae ornare a, aliquam a nunc. In id magna pellentesque tellus posuere
adipiscing. Sed non mi metus, at lacinia augue. Sed magna nisi, ornare in mollis in,
mollis sed nunc. Etiam at justo in leo congue mollis.Nullam in neque eget metus hendrerit
scelerisque eu non enim. Ut malesuada lacus eu nulla bibendum id euismod urna sodales. “;
/*压缩字符串*/
$compressed = gzcompress($string);
echo “Original size: “. strlen($string).” ”;
/* 输出原始大小 Original size: 800 */
echo “Compressed size: “. strlen($compressed).” ”;
/* 输出压缩后的大小 Compressed size: 418 */
// 解压缩
$original = gzuncompress($compressed);
