PHP Associative Array

Associative array initialization:

<?PHP
	$arr = array("one"=>"Monday","two"=>"Tuesday","three"=>"Wednesday",
	"four"=>"Thursday","five"=>"Friday","six"=>"Saturday","seven"=>"Sunday");
?>

Initialize element by element and count the length of the array:

<?PHP
	$arr = array();
	$arr["one"] = "Monday";
	$arr["two"] = "Tuesday";
	$arr["three"] = "Wednesday";
	$arr["four"] = "Thursday";
	$arr["five"] = "Friday";
	$arr["six"] = "Saturday";
	$arr["seven"] = "Sunday";
	
	echo count($arr); //7
?>

Iterate through the associative array:

<?PHP
	foreach($arr as $num=>$d)
	{
		echo "$num, $d\n";
	}
?>

Associative array can also be iterated by list()=each():

<?PHP
	while (list($key,$value) = each($arr))
	{
		echo "$key, $value\n";
	}
?>
