Extracting values out of a array

[H-O-V]

I have an array of values from a form ($_POST) and they are all checkboxes so

carrots => on
apples =>

etc

is there any way of selecting just the on ones in another array?

How do you want them to be selected? If you are going to loop through and do something to each one anyways, you don't really need any extra code.

foreach ($_POST as $key => $value)
{
	if ($value == "on")
	{
		// do something.
	}
}

Dan's solution will work 100% although another way of doing it would be like:-

<?php
$_POST = array('banana'=>'on','orange'=>'on','grapefruit'=>'off','lettuce'=>'on');

function check_on($setting, $fruit)
{
	if ($setting == 'on')
	{
		echo $fruit.' is on</br>';
	}
}

array_walk($_POST, 'check_on');
?>
