Question

Is there a way that I can have PHP get a file by a Regexp search? I know how to open and read a directory no problem, but finding a particular file is the problem.

Here is an example, I have a logo which may end in any of the following extensions: .bmp, .png, .jpg, .jpeg, or .gif. However, the name of the file will always be icon.someext.

$filesDirectory = scandir("/files");

foreach($filesDirectory as $file) {
    [Regexp find logo here] ? $logo = $file : null;
}

echo $logo; // Returns something like logo.png

Thank you for your time.

You can use glob with wildcard and GLOB_BRACE:

$files = glob("icon.{png,jpg,jpeg,gif,bmp}", GLOB_BRACE);
