Replace url variable / add variable function.

[rlemon]

Hey everyone,
This is the function I use when replacing url variables, or adding a new variable.

I realize there are holes but for the most part as long as there are no crazy characters in the url or the variables you will be ok.

PHP Code:

function replaceUrl($url,$uKey,$uVal){
    $Qurl = explode("?",$url);
    $arr = explode("&",$Qurl[1]);
    $r = ''; $set = 0;
    for($i=0;$i<sizeof($arr);$i++){
        $arr2 = explode("=",$arr[$i]);
        if($arr2[0] == $uKey){
            $arr2[1] = $uVal;
            $set = 1;
        }
        $r.=$arr2[0]."=".$arr2[1]."&";
    }
    if($set == 0){
        $r.= $uKey."=".$uVal;
    } else {
        $r = rtrim($r, "&");
    }
    return $Qurl[0].'?'.$r;
} 


usage:

PHP Code:


print replaceUrl('http://yourDomain.com/index.php?test=1&name=rlemon&age=19','name','rob lemon');
