How do I remove the first element from an array?
Often you want to add or remove values from the start or end of an array. To remove the first value in the array and see what it is, you can use the array_shift function in PHP:
$values = array(1,2,3,4,5,6,7,8,9,10);
$first = array_shift($values);
echo "First value was: $first";
Which tells us this:
First value was: 1
 => 2
 => 3
 => 4
 => 5
 => 6
 => 7
 => 8
 => 9
 => 10
Notice how the keys get re-assigned after the call to array_shift, so that '2' now has a key of zero whereas in the initial array that key referenced the number '1' which has now been removed from the array.
