[php]array_intersect_assoc 兩個陣列所引值的交集計算

(PHP 4 >= 4.3.0, PHP 5)

官方範例：
<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "green", "yellow", "red");
$result_array = array_intersect_assoc($array1, $array2);
?>

Array
(
    [a] => green
)

其它範例：
<?php
$array1 = array("green","brown","red","blue");
$array2 = array("green","brown2","blue", "red");
$result_array = array_intersect_assoc($array1, $array2);

print_r($result_array);
?>

Array ( [0] => green )
