php loop that creates directories using numbers that count up within 4 character spots

Question

I have a php loop and I have the code that creates a directory...

<?php

for ($i = 0; $i < 925; $i++){


    if (!file_exists('C:\wamp\www\maindirectory\mydirectory\0001')) {
        mkdir('C:\wamp\www\maindirectory\mydirectory\0001', 0777, true);
    }
}

?>

Obviously this code will not work. However, where 0001 is in the above code, I need it to count up as 0001, 0002, 0003, etc. The last directory would be 0925. How can I do this?

Whats this line all about "; I would guess if you removed that the script might compile and run — RiggsFolly

@RiggsFolly or even just str_repeat( '0', 4 - strlen( $i ) ).$i — MonkeyZeus

You could use sprintf => http://www.php.net/manual/en/function.sprintf.php

In your case:

mkdir('C:/wamp/www/maindirectory/mydirectory/' . sprintf("%04d", $i), 0777, true);

I think you will manage to finish the code.
