How to clear array elements in php

The way PHP clears array elements is to use the unset function, such as [unset($array[1]);]. It should be noted that if we use the unset function to clear the array elements, it will not change other keys of the array.

The operating environment of this article: windows10 system, php 7.3, thinkpad t480 computer.

If we want to delete an element in the array, then we can use the unset() or array_splice() method. Here we introduce the unset method.

Note: If we use the unset() method, it will not change other keys (keys). If we want to reorder other keys (keys), we can use the array_values() method.

Implementation code:

<?php
$array = array(0 => "a", 1 => "b", 2 => "c");
unset($array[1]);
//↑ 你要删除的数组元素值的键print_r($array);
?>

Output result:

Array (
    [0] => a
    [2] => c
    )
