用js进行url编码后用php反解以及用php实现js的escape功能函数总结

function js_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;
}

复制代码 代码如下:

function phpescape($str)
{
$sublen=strlen($str);
$retrunString="";
for ($i=0;$i{
if(ord($str[$i])>=127)
{
$tmpString=bin2hex(iconv("gb2312","ucs-2",substr($str,$i,2)));
//$tmpString=substr($tmpString,2,2).substr($tmpString,0,2);window下可能要打开此项
$retrunString.="%u".$tmpString;
$i++;
} else {
$retrunString.="%".dechex(ord($str[$i]));
}
}
return $retrunString;
}
