Array Operators

The only array operator in PHP is the + operator. It appends the right handed array to the left handed, whereas duplicated keys are NOT overwritten.

<?php $a = array("a" => "apple", "b" => "banana");
$b = array("a" =>"pear", "b" => "strawberry", "c" => "cherry");

$c = $a + $b;

var_dump($c); ?>

When executed, this script will print the following:

<?php array(3) {
 ["a"]=>
 string(5) "apple"
 ["b"]=>
 string(6) "banana"
 ["c"]=>
 string(6) "cherry"
} ?>
