How do i count same values in an array and store it to a variable?
提问by yohdaman
$items = explode(',',$product); // values is 4,2,4,2,2,4
$unique_items=array_unique($items); // gives me 4,2
What code should be next to give me 4 = 3 , 2 = 3 and store the number of values to a variable?
接下来应该是什么代码给我 4 = 3 , 2 = 3 并将值的数量存储到变量？
