adding a zero to an integer

[gerkintrigg]

I'm trying to work out how to format a variable as two digits even if it's one...

so:

1 becomes 01, 2 becomes 02, but 10 stays as 10...

 

is there an easy way? i tried number_format but that seems to only be for float vars.

 

thanks.

Try something like this:

function 1_to_2($number){
  $str="".$number;//convert the number to a string
  if(strlen($str)==1){//if the number has only 1 digit
    $str="0".$str;//add another
  }
return $str;//return the number
}

Will sprintf() not do it?

Probably. Have a look at the manual entry for it.

<?php

$var = 1;

printf('Value is %02d', $var);
        // returns Value is 01
?>
