PHP and Numbers

I am retreiving a number from an ID field in the database, the number is stored in the database as 0036. I want to display this number but incremented by 1 in my PHP script. I tried doing this but instead of displaying 0037 it just displays 37. How can I make this work?

This is what I tried doing:

$value=$row['id']+1;

Code (markup):

 

you would have to do something like

$tmp = intval($row['id'] + 1);
$len = strlen($tmp);
if($len == 1)
 $value = '000'.$tmp;
elseif($len == 2)
 $value = '00'.$tmp;
elseif($len == 3)
 $value = '0'.$tmp;
else
 $value = $tmp;

PHP:

 

Or, if you don't enjoy doing so much typing, you can just use:

$value = sprintf("%04d", $row['id'] + 1);

Code (markup):

 

Cheers SmallPotatoes. Will that function also work if the number is for example: 0123
And I want it to increment by one to make it 0124

 

Yep, it will work with any number from 1-4 digits. If the number is more than 4 digits it will just leave it alone.

e.g., 255 becomes 0255, but 12345 remains 12345. To change the number of digits it pads out to, just change the 4 in the first argument to sprintf.

 

Fantasic mate! Thanks for that

 

str_pad would probably be the best way.
