使用數(shù)組相交
$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);
