Submitting a form with every field the same name

Okay, so I learned that if I have a form like:

<form method="post" action="arrayplay2.php">
<input type="checkbox" value="1" name="todelete[]"/>
<input type="checkbox" value="2" name="todelete[]"/>
<input type="checkbox" value="3" name="todelete[]"/>
<input type="checkbox" value="4" name="todelete[]"/>
<input type="submit" value="delete" name="delete"/>
</form>

that the attribute name="todelete[]" initiates an array. How? And then how do I access this and the values in each one with the $_POST superglobal on my arrayplay2.php script?

With form like that you get indeed an array in $_POST superglobal named todelete. Array will be numeric array starting with index 0.

You can loop that array:

foreach($_POST['todelete'] as $val){
   echo $val;
}

Or you can directly access desired index:

echo $_POST['todelete'][2];
