gb2312编码：
复制代码 代码如下:
function unescape($str) {
$str = rawurldecode($str);
preg_match_all(/%u.{4}|.{4};|d+;|.+/u,$str,$r);
$ar = $r[0];
foreach($ar as $k=>$v) {
if(substr($v,0,2) == %u)
$ar[$k] = iconv(ucs-2,gbk,pack(h4,substr($v,-4)));
elseif(substr($v,0,3) == )
$ar[$k] = iconv(ucs-2,gbk,pack(h4,substr($v,3,-1)));
elseif(substr($v,0,2) == ) {
$ar[$k] = iconv(ucs-2,gbk,pack(n,substr($v,2,-1)));
}
}
return join(,$ar);
}
utf8编码：
复制代码 代码如下:
function unescape($str){
$ret = '';
$len = strlen($str);
for ($i = 0; $i if ($str[$i] == '%' && $str[$i+1] == 'u'){
$val = hexdec(substr($str, $i+2, 4));
if ($val else if($val >6)).chr(0x80|($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;
}
以上就介绍了the great escape php下escape解码函数的实现方法，包括了the great escape方面的内容，希望对php教程有兴趣的朋友有所帮助。
