Can someone please help me with this preg_match

if (preg_match('~[^A-Za-z0-9_\./\]~', $filepath))
    // Show Error message.

I need to match a possible filepath. So I need to check for double slashes, etc. Valid file path strings should look like this only:

mydir/aFile.php

or

mydir/another_dir/anyfile.js

So a slash at the beginning of this string should be checked also. Please help.

Thanks :)
