How to use associative array in php?

[Die_heart]

<?php
// create an associative array that is a cart holding items and prices
$cart_array = array(
"cereal" => "5.00",
"coffee beans" => "2.50",
"bananas" => "3.50",
"onion" => "1.00",
"lettuce" => "2.40",
"tomato" => "1.00",
);
// and here is how you can output any key's value you choose
echo "Bananas cost $" . $cart_array["bananas"] . " at this store.";
echo "<br /><br />";
// And here is how you can print the whole array for viewing and debugging
print_r($cart_array);
?>

Associative arrays use named keys that you assign to them. For example:
<?php
$age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43");
echo "Peter is " . $age['Peter'] . " years old.";
?>
You can also use a loop through associated array.
