README

Ensures that filenames are unique by appending a suffix to the filename.

If a file with $filename does not already exist, then the original filename is offered instead of an altered one.

Examples

For a file named test_file.txt, FilenameSuffixer::suffix will return:

• test_file.txt if the file does not exist
• test_file-1.txt if a file called test_file.txt already exists
• test_file-2.txt if files called test_file.txt and test_file-1.txt already exist
• etc...

Versioning

This project follows semantic versioning.

Installation

composer require mattgorle/filename-suffixer

Usage

use Gorle\FilenameSuffixer\FilenameSuffixer;

$filename = 'your_file.jpg'

$safeFilename = FilenameSuffixer::suffix($filename); 
// - your_file.jpg if the file does not already exist
// - your_file-1.jpg if your_file.jpg already exists
// - your_file-2.jpg if your_file-1.jpg already exists
// - etc...

Customising behaviour

I have tried to select sensible defaults, but you can modify several parameters to suit your individual use case by changing the value of the static properties on FilenameSuffixer.

You can customise the following:

Examples

use Gorle\FilenameSuffixer\FilenameSuffixer;

FilenameSuffixer::$extensionSeparator = '_'; 
FilenameSuffixer::$pathSeparator = ':';
FilenameSuffixer::$suffixStartsAt = 31;
FilenameSuffixer::$suffixSeparator = '_';

Resetting the suffixer after changing defaults

Help, I've changed loads of stuff and now I can't find my way back!!! 😭

Simply call FilenameSuffixer::reset() and the initial defaults will be reinstated.

Honestly, I don't know if this is going to be a useful feature - it came up in testing and it feels more like a consequence of implementing this as a static class. Probably needs some thought!
