[RESOLVED] Numbering files, 1,2,3 to 01,02,03

[curb]

I'm trying to add 0 before 1-9 only. 10+ won't have the 0. Here's the function I have so far...

$i++;
        $x=0 ;
        if(@$checkDir = opendir($dir))
        {
            $cDir = 0;
            $cFile = 0;

        // check all files in $dir, add to array listFile
        while($file = readdir($checkDir))
        {
            if($file != "." && $file != "..")
            {
                if(is_dir($dir . "/" . $file))
                {
                    $listDir[$cDir] = $file;
                    $cDir++;
                }
                else
                {
                    $listFile[$cFile] = $file;
                    $cFile++;
                }
            }
        }

        // rename files
        if(count($listFile) > 0)
        {
            sort($listFile);

            for($k = 0; $k < count($listFile); $k++)
            {
                $spacer = "";

                for($l = 0; $l < $i; $l++)
                    $spacer .= "&emsp;";

                // get the extention of the file    
                $ext = explode(".", $listFile[$k]) ;
                // display what it does
                print("") ;    
                //rename the file
                if(@rename($dir . "/" . $spacer . $listFile[$k], $dir . "/" . $name . ($k+1) . "." . $ext[1]))
                    $x++ ;
                else
                {
                    // display message if error append
                    print("") ;
                }
            }
        }
        // closing directory
        closedir($checkDir);

        print("") ;
    }
    else
    {
        // display message if error append
        print("") ;
    }

why don't you simply use [man]printf[/man] or [man]sprintf[/man]? here is a simple example:

for ($i = 1; $i <= 20; $i++)
{
	printf('%02s', $i);
	echo '<br>';
}

Look at the [man]str_pad[/man] ...

Problem solved. I used this as the result:

$i > 9 ? $i : "0".$i;
