Hi,

I want to create a file which includes a three digit number. For example, file001.txt, file021.txt etc.

I have used the following code:

$ext = "txt";
$i = 004;
$TheFile = "file $i.$ext";

but $TheFile = "file4.txt"

How can I get $TheFile = "file004.txt" ?

Thank you.

Jan

you have to use a string since int are alway striped of there 0

$ext = "txt";
for($i=1;$i<500;$i++)
{
   if($i>=100)
        $zero="";
   else if ($i>=10)
         $zero="0";
   else
         $zero="00";
   $TheFile = "file".$zero.$i.$ext";
}

IF , ELSE , WHILE isn't that what life is all about

Thank you for your help. I'm a PHP beginner and I came across the following solution which seems to work:

$i=str_pad($i,3, "0",STR_PAD_LEFT);

Is this a good solution? I am eager to learn!

php.net

bokmark it.
always go there first for php questions. chances are it has the answer. if that doesn't succeed ask for clarificaton here or at the dev net (linked to there)

dev net seemsfaster but same quality for php responses. this is bettter for everything else.

they are by far the best stes i've found for help

POSIX. because a stable os that doesn't have memory leaks and isn't buggy is always good.

Even better:

<?php
$TheFile = sprintf(\"file%3d.%s\", $i, $ext);
?>
