dedecms拓展函数

这些函数是在一个视频站点中复制下来的,发布出来做一个备份,也许以后能用的上,至于函数的作用可以看一下具体代码,这里就不做解析了。

//解密js escape加密字符串
function unescape($str) {
$ret = '';
$len = strlen ( $str );
for($i = 0; $i < $len; $i ++) {
if ($str [$i] == '%' && $str [$i + 1] == 'u') {
$val = hexdec ( substr ( $str, $i + 2, 4 ) );
if ($val < 0x7f)
$ret .= chr ( $val );
else if ($val < 0x800)
$ret .= chr ( 0xc0 | ($val >> 6) ) . chr ( 0x80 | ($val & 0x3f) );
else
$ret .= chr ( 0xe0 | ($val >> 12) ) . chr ( 0x80 | (($val >> 6) & 0x3f) ) . chr ( 0x80 | ($val & 0x3f) );
$i += 5;
} else if ($str [$i] == '%') {
$ret .= urldecode ( substr ( $str, $i, 3 ) );
$i += 2;
} else
$ret .= $str [$i];
}
return $ret;
}
