assigning array from form

[themanwhowas]

so this html code below

<input type="checkbox" name="interest[]" value="driving">driving
<input type="checkbox" name="interest[]" value="skiing">skiing

would asign interest as an array which can be printed below

echo 'your interests are as follows:<ul>';
foreach($_POST['interest'] as $val)
	{
		echo "<li>$val</li>";
	}
echo '</ul>';

but the sizeof() $val is one and is always the last checked checkbox.

normally i would asign an array as

$var=array('1'=>'sway', 'pray', 'tray');

but clearly there is no assignment of the array $val but it is printed but after the initial printing it is lost unless i redo the $_POST['interest'] etc.

i can accept this but what kind of learning method is that? i blame my book for not explaining properly.

can anybody please give me more info on the process going on here?
i appreciate it

if you do

var_dump($_POST['interest']);

It will show the contents of the array

Using foreach will loop through each element of the array and store it in $val in turn.

Remember, arrays start at 0 unless otherwise specified.

Once you've used foreach the latest value assigned will be kept in $val i.e. the value of the last checkbox. $val isn't an array it's just the current element of the array or once you've been through the foreach loop, the last element of the array.

If you want to use the array again you'll have to refer to $POST['interest'] or assign it to another name e.g. $new_array = $POST['interest'];

aha. my book explained it as if $val was now an array as if the handling of the interest[] name made it an array due to the [].
thank you
