查找所有数组中存在的值（PHP）

Question

查找所有数组中存在的值的最快方法是什么。$arrayOfArrays[] = [76,964,34,66775,3,88,99,69];$arrayOfArrays[] = [69,55,65,657,436,6345,8654];$arrayOfArrays[] = [54,543,496,3455,47556,69,234,436557];$arrayOfArrays[] = [4564536,4543,777,3445,43768,2334,69,35,574];预期输出为[69]

Answer 1

使用数组相交

$arrayOfArrays[] = [76,964,34,66775,3,88,99,69];

$arrayOfArrays[] = [69,55,65,657,436,6345,8654];

$arrayOfArrays[] = [54,543,496,3455,47556,69,234,436557];

$arrayOfArrays[] = [4564536,4543,777,3445,43768,2334,69,35,574];

$intersect = array_intersect(

    $arrayOfArrays[0],$arrayOfArrays[1],$arrayOfArrays[2],$arrayOfArrays[3]

);

$arrayOfArrays[] = [76,964,34,66775,3,88,99,69];

$arrayOfArrays[] = [69,55,65,657,436,6345,8654];

$arrayOfArrays[] = [54,543,496,3455,47556,69,234,436557];

$arrayOfArrays[] = [4564536,4543,777,3445,43768,2334,69,35,574];

$intersect = call_user_func_array('array_intersect', $arrayOfArrays);

Answer 2

$arrayOfArrays[] = [76,964,34,66775,3,88,99,69];

$arrayOfArrays[] = [69,55,65,657,436,6345,8654];

$arrayOfArrays[] = [54,543,496,3455,47556,69,234,436557];

$arrayOfArrays[] = [4564536,4543,777,3445,43768,2334,69,35,574];

$result = call_user_func_array('array_intersect', $arrayOfArrays);
