Specifying Amount of Digits

[funstein]

Hello there,

 

I have a script that has two variables called oc_id and oc_pos. These variables, oc_pos and oc_id, are summoned from a database based on user input. Sometimes it is 120, sometimes 50, sometimes 5. So the number of digits varies.

 

Now I need to convert these into an identifier string for some purpose. But I want them to be 3 digits always, for example, 120, 050, 005. How is that possible?

[trq]

echo sprintf("[%03s]\n",   $oc_id);

Alternately:

 

str_pad( $number, 3, '0', STR_PAD_LEFT );
