A function I made for use in CodeIgniter, search entire result set and when the match is evaluated, returns the value specified of said row

/**
 * Searches a CI resultset, and when the match is evaluated, returns the specified value
 * Both params of $match array are required
 * 
 * Example of use: if you want to get the ID of an item where the row 'type' is 'user'
 * you do:
 * 
 * Take note: The comparison doesn't take account of whitespace characters before and
 * after the data of the result sets rows
 * 
 * get_item_where_key($result, 'id', $array('type' => 'user');
 * 
 * @param $result_set 	object
 * @param $key			string
 * @param $match		array
 *

function get_item_where_key($result_set, $item, $match){
	
	$key = array_keys($match);
	$key = $key[0];
	
	foreach ($result_set as $row)
	{		
		if(trim($row->$key) == trim($match[$key]))
		{
			return $row->$item;
		}
			
	}
	
	return FALSE;
