Remove text after certain word

Question

I have dynamic link build from variable :

/Tinkle/Matte/BlackHyper/Black/Gunmetal

How can I remove all text after variable value "BlackHyper" to become: "/Tinkle/Matte/BlackHyper"

I try rtrim :

$param="BlackHyper";
$str="/Tinkle/Matte/BlackHyper/Black/Gunmetal";
rtrim($str,$param);

No luck , remove some letters....

RTrim doesnt work like this.

You need to do something like this

$pos = strpos($str, $param);
$endpoint = $pos + strlen($param);
$newStr = substr($str,0,$endpoint );

This will create a new string (there might be a bug or two I havent tested it) with all characters up to your param.

OP wants to incelude `$param` in the result, so you should use `$pos+strlen($param)`. – moinudin Jan 16 '11 at 09:44
newStr will contain the changed string, $str will remain the same. Thats the way it works! – Toby Allen Jan 16 '11 at 10:38

Maybe you can use strstr function?

$a = "before/after";
$b = strstr($a, "/",true); // gets text before /
$c = strstr($a, "/"); // gets text after /
