date uguali per files diversi

[oronze]

prova così:

$dircontent = scandir($curdir);
$dates=array();
	foreach($dircontent as $file) {
		if ( isValid($file,$sfxs) ) {
			$dat = date("d-m-Y", filemtime($file));
			if(!in_array($dat, $dates){
			       	$dates[] = $dat;
			       	echo "<option value='1'>$dat</option>";
                        }
	        }
	}
