How to delete the last element of an array in PHP

In PHP, you can use the array_pop() function to delete the last element in an array. This function returns the deleted element.

Sample code:

$myArray = [1, 2, 3, 4, 5];

$lastElement = array_pop($myArray);

echo "被删除的元素是：" . $lastElement . "<br>";

print_r($myArray);

The output result is:

被删除的元素是：5
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
)

In the above example, we created an array containing 5 elements$myArray, and then use the array_pop() function to delete the last element 5 and assign it to the variable $lastElement. Finally, the print_r() function is used to output the array $myArray with the last element removed.

In addition to using the array_pop() function, you can also use the unset() function to set the last element in the array to NULL or delete the element:

$myArray = [1, 2, 3, 4, 5];

unset($myArray[count($myArray) - 1]);

print_r($myArray);

The above code uses the unset() function to delete the last element 5 in the array and output the remaining elements.

No matter which deletion method is used, remember to ensure that the key values ​​of the array are still continuous after deleting an array element.
