array_intersect函数在PHP中用于计算数组的交集。它接受两个或多个数组作为参数,并返回一个包含所有输入数组共有元素的新数组。 示例代码 php <?php // 定义两个 $array1 = array(1, 2, 3, 4, 5); $array2 = array(4, 5, 6, 7, 8); // 使用array_intersect函数计算交集 $intersection = arra...
可以通过array_intersect函数来比较两个PHP数组,并返回一个新数组,其中包含两个数组中都存在的元素。以下是一个示例代码:$array1 = array("red", "green", "blue"); $array2 = array("red", "yellow", "blue"); $intersection = array_intersect($array1, $array2); print_r($intersection); 复制代码...
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...
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...
