Loop and increment filename

[wiggst3r]

Hi

 

I have a script that adds files to a folder, that I get from FTP.

I download these files everyday and are txt files, but are iin CSV format.

 

In this folder I currently have 3 files. 1.csv, 2.csv and 3.csv

 

Rather than me renaming them everyday, I'm looking to write a script to auto-increment the filename.

 

So i'm looking to loop through the files in the folder, If there is no filename which is 4.csv, the file that has been downloaded will be renamed to this.

The next day, the file will be renamed to 5.csv etc

 

Does anyone know the code to do this?

 

Thanks

something like:

<?php

$i = 0;
while ($i <= 500) {
$filename = '/path/to/'.$i.'.txt';

if (file_exists($filename)) {
do stuff here
} else {
do other stuff here
}
$i++;
}
?>

The test file is named download.txt

 

How could i implement this into that piece of code?
