I spent a while to sort out some integer results of the bzdecompress, so maybe it'll be useful for somebody else also...
(Constants from the sources.)

示例

<?php
$start_str = "This is not an honest face?";
$bzstr = bzcompress($start_str);
echo "Compressed String: ";
echo $bzstr;
echo "\n<br />\n";
$str = bzdecompress($bzstr);
echo "Decompressed String: ";
echo $str;
echo "\n<br />\n";
?>
