How to get file name without file extension?

271

I have this PHP code:

function ShowFileExtension($filepath)
{
    preg_match('/[^?]*/', $filepath, $matches);
    $string = $matches[0];

    $pattern = preg_split('/\./', $string, -1, PREG_SPLIT_OFFSET_CAPTURE);

    if(count($pattern) > 1)
    {
        $filenamepart = $pattern[count($pattern)-1][0];
        preg_match('/[^?]*/', $filenamepart, $matches);
        return strtolower($matches[0]);
    }
}

If I have a file named my.zip, this function returns .zip.

I want to do the reverse, I want the function to return my without the extension.

The file is just a string in a variable.

php file string

As an alternative to pathinfo(), you can use

basename() — Returns filename component of path

Example from PHP manual

$path = "/home/httpd/html/index.php";
$file = basename($path);         // $file is set to "index.php"
$file = basename($path, ".php"); // $file is set to "index"

You have to know the extension to remove it in advance though.

However, since your question suggests you have the need for getting the extension and the basename, I'd vote Pekka's answer as the most useful one, because it will give you any info you'd want about the path and file with one single native function.
