I have an array $myArray1 with some numerical values like 2 5 7 13 23 25 Another array $myArray2 has numerical values like 3 4 7 11 13 25

My requirement is to get a third array $myArray3 having only those values of $myArray1 that are not present in $myArray2 i.e. 2 5 23

最满意答案

$myArray1=[2,5,7,13,23,25]; $myArray2=[3,4,7,11,13,25]; $myArray3=array_diff($myArray1,$myArray2); var_dump($myArray3); // 2, 5, 23 $myArray1=[2,5,7,13,23,25]; $myArray2=[3,4,7,11,13,25]; $myArray3=array_diff($myArray1,$myArray2); var_dump($myArray3); // 2, 5, 23
