该函数接受两个或更多个数组作为参数,并返回一个数组,其中包含了所有输入数组中共同的元素。 以下是使用array_intersect函数的示例: $array1 = array('a', 'b', 'c', 'd'); $array2 = array('b', 'c', 'e', 'f'); $intersection = array_intersect($array1, $array2); print_r($intersection...
下面是一个简单的示例,演示如何使用 array_intersect() 函数来获取两个数组的交集: php <?php $array1 = [1, 2, 3, 4]; $array2 = [3, 4, 5, 6]; $intersection = array_intersect($array1, $array2); print_r($intersection); ?> 4. 提供一个示例代码片段,展示如何在实际应用中使...
php$fruit1=array("Apple","Banana","Orange");$fruit2=array("Pear","Apple","Grape");$fruit3=array("Watermelon","Orange","Apple");$intersection=array_intersect($fruit1,$fruit2,$fruit3);print_r($intersection);//输出结果: // Array ( [0] => Apple )?> 本例子将返回在fruit1数组中出...
