Pop and return the last element from an array using PHP function 'array_pop'

Use the PHP function "array_pop" to pop from the array and return the last element

In PHP, we often need to process array data. Sometimes, we need to remove the last element from the array and operate on it. PHP provides a very convenient function to implement this function, which is the "array_pop" function.

The "array_pop" function is used to pop and return the last element from the array. Its syntax is as follows:

mixed array_pop ( array &$array )

This function accepts an array as a parameter, removes the last element of the array from the array, and returns this element. If the array is empty, returns null.

Next, let's look at a code example using the "array_pop" function:

<?php
// 定义一个数组
$fruits = array("apple", "banana", "orange", "grape");

// 使用array_pop函数弹出并返回最后一个元素
$last_fruit = array_pop($fruits);

// 输出弹出的元素
echo "弹出的元素是：" . $last_fruit . "
";

// 输出剩余的数组
echo "剩余的数组是：
";
print_r($fruits);
?>

The above code defines an array named "fruits", which contains some fruit names. Then, we pop the last element using the "array_pop" function, assign it to the "last_fruit" variable, and output it on the screen. Next, we use the "print_r" function to print out the remaining array.

If you run the above code, you will get the following output:

弹出的元素是：grape
剩余的数组是：
Array
(
    [0] => apple
    [1] => banana
    [2] => orange
)

As you can see, the "array_pop" function pops the last element "grape" from the array and returns it to us . The remaining array only contains the remaining fruit names.

Summary:

By using PHP's "array_pop" function, we can easily pop and return the last element of an array. This function is very useful for working with array data. Hope this article is helpful to you!
