Adding a leading zero to a single digit number
Posted: Tue Feb 25, 2003 8:22 pm
I've browsed through the manual but can't find a way of doing this. What I'm trying to achieve is to always have a 2 digit number - so that whenever a single digit is found (0,1,2,3,5,6,7,8,9) then they will be converted to 00,01,02 etc.
This is what I came up with but it doesn't seem to work.
Any suggestions?

Code: Select all
$gridnumber = '8';
//adds a leading zero to single digits 1 to 9)
$num_of_numbers = count_chars($gridnumber);
if ($num_of_numbers == '1')
{
$gridnumber_array[] = '0';
$gridnumber_array[] = $gridnumber;
$gridnumber = implode('', $gridnumber_array);
}
