add operation (math)

[nagasea]

how to add this :

0052 + 1

I want the result is 0053 instead of 53

how to do that ?
any idea ?

think about

052 + 1 =     053

00051 + 1 = 00052

You need something like this.

<?
$i='00052';
$j = '1';
$len = strlen( $i );

printf( "%0${len}d",$i+$j );
?>

Bee careful using numbers with leading zeros. They are OK in a string but if used as a constant, (not in quotes) they will be converted to the octal equiv.

Other way:

$a="0052";
print str_pad($a+1,strlen($a),"0",STR_PAD_LEFT);
