for loop on array

buducom

I have the following code:

for ($grouped = 0; $grouped < $sizearray; $grouped++){
$manymails = sizeof($POST["email"][$grouped]);
echo $manymails;
for ($loop = 0; $loop < $manymails; $loop++){
echo $POST["email"][$grouped][2];
echo '<input type=hidden value="'.$_POST["email"][$grouped][$loop].'" name="emailarray['.$countrows.']">';
$countrows += 1;
}
}

The POST variable email has the following entry for example
because it comes from checkboxes
$POST["email"][1][2] contains for example daniel@imcworld.com
$POST["email"][1][0] doesnt contain anything.

the code above tries to return $POST["email"][1][0]
but what i am looking for is $POST["email"][1][2]
how can i check which is the last element of an array that contains a string and then with an if, exclude all elements
which do not include a string/content

thank you

I think you might be confused as to what data checkboxes send.

Here's a template for checkbox form and code to handle it.

<html>
<head><title>Checkbox POST test</title></head>
<body>
<form action="<?=$_SERVER[PHP_SELF]?>" name="frm" method="POST">
Send some $_POST variables
<hr /><input type="checkbox" name="email[]" value="fred@bloggs.com">Fred
<br /><input type="checkbox" name="email[]" value="jim@smith.co.uk">Jim
<br /><input type="checkbox" name="email[]" value="alan@jones.co.uk">Alan
<br />
<br /><input type="submit" value="Send">
</form>
<hr />The number of emails checked is [<?=count($_POST[email])?>].
<br />
<hr />
Here's a list of the $_POST[email] variables sent by the page:
<br />
<?php
if($_POST[email]){
	foreach($_POST[email] as $id => $val){ 
		echo '<br />$_POST[email]['.$id.'] = '.$val;
	}
}
?>
<hr />
</body>
</html>

Hope that helps!
