get an end of the array.

hi phpfreaks,

 

I want change the last value when iterating through an array but I can't seem to get to work. I can never get to  the echo housing but can't work out why any advice would be great.

				foreach ($headings as $key => $cValues){
					$cols .= $key.",";
					if(current($headings)== count($headings)){
						echo "housing";
						$cols .= $key;
						break;
					}
				}

current() returns the value, not the key. If $headings is a normal array (not an associative array) then you need to compare count() with the key.

Also, if the count is N then the key will always be between 0 and N-1. So that will never match either.

 

However you don't need a loop in the first place.

$cols = implode(",", array_keys($headings));

<?php

$headings = array(
'test'=>'one',
'blahblah'=>'two',
'lastone'=>'three'
);
end($headings);
$lastKey = key( $headings );

foreach ($headings as $key => $cValues){
if($key == $lastKey){
	echo $cValues;
}
}

?>

 

requinix probably has the _better_ answer though.

I know it's not the total of what you are doing, but FYI you can also use array_pop to remove the last element of the array, and array_push to add something new to the end.
