Question

I need help about file manipulation in PHP.
I have 4 file with known names and UNKNOWN extensions.
Like that:

Y923BBBB.E120506
Y924BBBB.E120606
Y925BBBB.E120706
Y926BBBB.E120806

and the file extensions changes everyday.
How i can cut or strip for every file the file extension, so that will stay only the names like that:

Y923BBBB
Y924BBBB
Y925BBBB
Y926BBBB

Anybody an idea?

Answer 1

Use strrpos to find the last . and substr to get only the substring up to that point. To find the files and rename them, use glob and rename:

foreach(glob('*') as $f) {
    if ($f == '.' || $f == '..') continue;
    $stripped = substr($f, 0, strrpos($f, '.'));
    rename($f, $stripped);
}
