摘要:
<?
functionphpescape($str)
{
$sublen=strlen($str);
$retrunString="";
for($i=0;$i<$sublen;$i++)
{
if(ord($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;
}
functionunescape($str){
$str=rawurldecode($str);
preg_match_all("/%u.{4}|",$str,$r);
$ar=$r[0];
foreach($aras$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($v,2,-1)));
}
}
returnjoin("",$ar);
}
?>
