$i = 0;
foreach ($Contents as $item) {
$item[number];// if there are 15 $item[number] in this foreach, I want get the value : 15
$i++;
}
如果你只需要循环内的索引,你可以使用
If you only need the index inside the loop, you could use
foreach($Contents as $index=>$item) {
// $index goes from 0 up to count($Contents) - 1
// $item iterates over the elements
}
