If you have a number X and you need to have it like 0000X you can use str_pad() or printf().
If you have the number 55, for exmaple, and you want it to look like 000055 do :

<?php
$Num
=55;
print
str_pad($Num, 6, "0", STR_PAD_LEFT);
?>


This will print 000055

You can also do this :
<?php
$Num
=55;
printf("%06d", $Num);
?>


This will also print 000055
