Need 3 zeros in variable

[Anon]

I have a variable that gets passed 3 digit numbers, when the variable is 19 I want it to be 019 so I can use it in a character string. How do I get it to keep the 0 in 019?

Hi,

You need to cast the variable as a string.

$varname = (string)$threedigitnumber;

And, if you're variable is missing zeros before you turn it into a string, you could add the following:

$string=$yourvariable;
for($i=1, strlen($string)<=3,$i++)
$string = "0".$string;

$var = sprintf("%03d", $var);

mumble mumble Takes one fourth the time of my code too.

And remember boys and girls, for loops use ';' as section delimiters, not ','.

Hi All,

What about:

str_pad($input, 3, "0", STR_PAD_LEFT);

Cheers,
