How to create a file that has no name but only extension in PHP?

Question

I'm trying to create a file using PHP but the problem is that the needed file has no name but only an extension. How can I do it? The present code just doesn't make the file but it also doesn't give me an error.

fopen( '.extension', 'w' )or die( 'ERROR MESSAGE' );

Files with only an extension and no name are treated as hidden in unix. To list them, you might call ls -la inside the terminal.

So the code you posted should just work fine. Note: you should always close the file opend with fopen!

$f = fopen( '.extension', 'w' );
if ($f) {
    fclose($f);
}
