Update Array Items in PHP

You can update array items by assigning a new value to an existing index or key.

$colors = array("red", "green", "blue");
$colors[0] = "yellow";

$person['age'] = 31;
print_r($person);
?>

(
    [0] => yellow

    [2] => blue
)
Array
(
    [name] => John
    [age] => 31
)
