PHP: Delete an element from an array 34 answers

---

To remove an element from an array,
unset($dataArray[0]);
Note that the other element indexes are the same.

或者，您可以使用array_shift，这也会重置数组上的索引，而未unset则不会。

$unsetTest = array('hey','now','brown','cow');
$shiftTest = array('hey','now','brown','cow');

unset($unsetTest[0]);
array_shift($shiftTest);

var_dump($unsetTest);
var_dump($shiftTest);

//output

array(3) {
  [1]=>
  string(3) "now"
  [2]=>
  string(5) "brown"
  [3]=>
  string(3) "cow"
}

array(3) {
  [0]=>
  string(3) "now"
  [1]=>
  string(5) "brown"
  [2]=>
  string(3) "cow"
}
