Quick and Simple Question

Ok, here's the question:

If I have a number like 001 and I using PHP to add 1 to it, ex:

<?php
$nmb = 001;

$nmb = nmb + 1;

echo($nmb);

?>

Will it print "002" or just "2".

I hope you understood that. Thanks in advance.

Why don't you just run it?

it will print 2. leading zero's are never
displayed.

in fact, initialising as $var = 001; is no different from $var = 1;

[non_zero]

That will print 2. Any zeros before a non-string value will always be omitted.

Is there any way I can get a number from 009 to 010 for instance without having the numbers omitted?

[mark_php]

Yes there is many ways but here is what i would do

<?php
$var1 = 009;
$var1++;
print "00".$var1;
/*
mabye it is'nt perfect code but im just not sure what you would need this for if so
mabye I could do better 🙂
hope this helps

*/
?>

also take a look at the str_pad function

Or you can use sprintf to control out the number is outputted:

<?
$num = 300;
$num2 = sprintf("%06d", $num);
echo "Original Number: " . $num;
echo "<br>";
echo "Modified Number: " . $num2;
?>
