recuperare valori da checkbox con stesso name

[Beppesan]

Prova così:

<?php 

if(!isset($_POST['submit']) || $_POST['submit'] != "inviato"){ ?>

	<FORM action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
		<INPUT type="checkbox" name="scelta" value="0" tabindex="1">a

		<INPUT type="checkbox" name="scelta" value="1" tabindex="3">b

		<INPUT type="checkbox" name="scelta" value="2" tabindex="2">c

		<INPUT type="checkbox" name="scelta" value="3" tabindex="4">d

		<INPUT type="submit" name="submit" value="inviato">
	</FORM>
<?php }
else {
	if(isset($_POST['scelta'])){
		for($i=0; $i<=2; $i++){
			$e = $i+1;
			echo "scelta $e :  ".$_POST['scelta'][$i];
		}		
			
			
	}


}
?>
