Bug Msg: The value of variable $array was never used.

[jtp51]

I keep receiving the following message on the class method noted below:

"The value of variable $array was never used."

I am not for sure why since I use the $array parameter in the foreach statement. Any suggestions on correcting this is greatly appreciated.

public function createMultiple($link, $array)
	{
		$item = $link->Container->Container->Data;
		$return = array();

	foreach($array as $key) {
		if(strpos($key, "|") !== false)
		{
			$return[] = substr($key, 1);
		}
		else
		{
			$return[] = $item[$key];
		}
	}
	return implode(",", $return);
}

Thanks,
