keys begin to look like class objects but in PHP.

$greeting = array (”English”=>”Hi there!”, );

echo $greeting[”English”];

or use each to reference elements

while ($current greeting = each ($greeting)){
echo $currentgreeting[”key”].”<BR>”;
echo $currentgreeting[”value”];
}

loop thru key and value were auto assigned by the =>

 or use a list

while(list ($language, $words) = each ($greeting)){
echo $language;
echo $greeting;
}
