取得2個陣列的交集函式 array_intersect

<?php
$array1 = array("a" => "green", "red", "blue");
$array2 = array("b" => "green", "yellow", "red");
$result = array_intersect($array1, $array2);
?>

<?php

$array1 = array("a" => "green", "red", "blue");

$array2 = array("b" => "green", "yellow", "red");

$result = array_intersect($array1, $array2);

$result會得到

  [0] => red
)

Array
