Please explain this sprintf() format

[Wuhtzu]

Hey

 

I have a problem understanding this format '%0ld %s' used in this sprint() call:

 

<?php
sprintf('%0ld %s', 10133760, 'KB')
?>

 

Note: The format is 0 (zero), l (lower case L) and d.

 

It seems to yield the same result regardless of whether or not the 0 and l is there:

 

<?php

sprintf('%0ld %s', 10133760, 'KB') //Output: 10133760 KB

sprintf('%0d %s', 10133760, 'KB') //Output: 10133760 KB

sprintf('%d %s', 10133760, 'KB') //Output: 10133760 KB

sprintf('%ld %s', 10133760, 'KB') //Output: 10133760 KB

?>

 

Why are 0l used if they make no difference? I can't seem to find them in the sprintf() manual page: http://php.net/sprintf. I stumbled upon the use here: http://www.phpriot.com/d/code/strings/filesize-format/index.html

 

Could someone please explain this to me?

From the website you referenced looking at the code they use the number one and not a lower case L.

 

So it should be:

sprintf('%01d %s', 10133760, 'KB') //Output: 10133760 KB
