Simple query - Read 5 when var=005?

How to remove the 0 before the number

[tomda]

Hi,

I call an include depending of GET['id'] variable.

Variable is checked with function but I have not yet found the solution to this.

When typing 005 instead of 5, everything works fine (because 005 and 5 are the same) except for calling the include (include005.php qnd include5.php are not the same).

What should I do to remove the zeros before any number?
So that 00000102 returns 102?

Thanks

Something like:

function delZero($t)
{
$chars = strlen($t);
for ($i=1;$i<=$chars;$i++)
{
if (substr($t,$i,1)!= "0") break;
}
$return = substr($t,$i,($chars-$i));
return $return;
}

...should do it.

Hey Bonusbana,

Perfect!

Thanks a lot

How about:

$val = $val - 0; # to convert to a number

or:

$val = intval($val); # to convert to an integer

In the spirit of scalability, use dcrombie's example.

If the script you're writing ever ends up having to go through 1000's of numbers you'll be glad you did :-)

Agreed, use dcrombie's example if you just want to erase the zeros. The function I provided might be helpfull in other cases though, f.ex if you want to know how many zeros there are or if there is another number/digit you want to delete.

Thank for your support.

Indeed the second choice is much more shorter.
