我正在编写一个系统，我需要一个函数来获取和删除数组的第一个元素.这个数组有数字，即

Hi I am coding a system in which I need a function to get and remove the first element of the array. This array has numbers i.e.

0,1,2,3,4,5

0,1,2,3,4,5

我如何遍历这个数组并在每次传递时获取值，然后将其从数组中删除，以便在 5 轮结束时数组将为空.

how can I loop through this array and with each pass get the value and then remove that from the array so at the end of 5 rounds the array will be empty.

推荐答案

您可以尝试使用 foreach/unset，而不是 array_shift.

You might try using foreach/unset, instead of array_shift. 

$array = array(0, 1, 2, 3, 4, 5);

foreach($array as $value)
{
    // with each pass get the value
    // use method to doSomethingWithValue($value);
    echo $value;
    // and then remove that from the array 
    unset($array[$value]);
}
//so at the end of 6 rounds the array will be empty
assert('empty($array) /* Array must be empty. */');
?>
