Get and remove first element of an array in PHP

Question

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

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.

Thanks in advance

You can use array_shift for this:

while (($num = array_shift($arr)) !== NULL) {
  // use $num
}
