如何进行PHP压缩（一点经验分享）

<?php

echo "原来比率<br />";

$str = ‘{.....}‘;

echo strlen($str).‘<br />‘;

//压缩率居中

$compressed = gzcompress($str, 9);

echo ‘gzcompress:‘.strlen($compressed).‘,‘."<br />"; //gzuncompress($compressed)

//压缩率并列最高

$compressed = gzdeflate($str, 9);

echo ‘gzdeflate:‘.strlen($compressed).‘,‘."<br />"; //gzinflate($compressed)

$bzstr = bzcompress($str, 9);

echo ‘bzcompress:‘.strlen($bzstr).‘,‘."<br />"; //bzdecompress($bzstr)
