0 at the beginning

[hosdank]

I have a variable which has, let say the value of 1. I want to tack on a zero at the beginning so it has the value of 01. Thanks

$var = '0' . $var; 

Note, that will make it a string. If it gets changed back to an integer, the zero will be removed.

Yeah, thanks anyway, but I got it by myself... That's the very basics, I don't know how I forgot

More generally, str_pad().
