Formating Strings

[titan7262]

How can I format a string from an input value '1' to '01' then typecasting it to string?

Thanks!

I am confused. It would always be a string.

$input = 1;

$input = '0' . $input; // it is a string

If you want the result to have two digits, even if the input has two digits, you can use sprintf:

$string = sprintf("%02d", $input);

Note that types aren't very important in PHP.

but what if the input has 3 or more?...

wouldnt it be better to always add a 0 to the input. or if 2 dont add zero. else add a zero

Then the result would still have 3 digits. Field width specifiers never truncate.

That would be far more complex, for no gain.
