number format

[chiprivers]

Is there a simple function that I can use to force 0's (zeros) infront of a given number so that it will always be a fixed number of digits long.

 

ie. If I want to always display a number as 5 digits and I am given the number 50, I want to force it to display as 00050.

you could check the strlen of the number variable and replace zeros as needed based on string length.

Yes, printf().

you can use str_pad function

 

echo str_pad(50,5,"0",STR_PAD_LEFT);

Or...as suggested.

 

<?php

  sprintf("%05d", 50);

?>
