string length

[nikko50]

Hello all🙂
I need help with a function. I would like a function that tests the string length. IF this length is 4 intergers long I would like to add a '0' in front. Any help would be appreciated.

if you are using strings then you might be able to use strlen() funtion and then add something in front with this

I hope this helps you

Thanks Trey!
Function convert ($id){
if (strlen($id)==4){
$id="0".$id;
return $id;
}
}

Is this only if it's 4 long? If you were just looking to pad the string with zeros, you could use [man]str_pad[/man]...
