Add a value to the end of an array using the array_push() function

Array is a data structure often used in programming. It allows us to combine multiple related data and operate them conveniently. In PHP, array is a very important data type that can be created through the array() function. In actual programming, we often need to add a value to the end of an array. PHP provides a very convenient function array_push() to achieve this function.

The array_push() function is a built-in function in PHP that adds one or more values ​​to the end of an array and returns the array length. It accepts two parameters, the first parameter is the array of values ​​to be added, and the second parameter is the value to be added to the end of the array. Furthermore, we can also add multiple values ​​to the array by passing multiple parameters and these values ​​will be added to the array in their order.

The following is a sample code that demonstrates how to use the array_push() function to add a value to the end of an array:

<?php
// 创建一个空数组
$color = array();

// 向数组中添加一个值
array_push($color, "red");

// 打印数组
print_r($color);
?>

The output result is:

Array
(
    [0] => red
)

You can see , a value "red" was successfully added to the array and is located at the end of the array.

In addition to adding a single value to the end of the array, we can also use the array_push() function to add multiple values ​​to the array at once. The following is a sample code that demonstrates how to add multiple values ​​​​to an array:

<?php
// 创建一个空数组
$color = array();

// 向数组中添加多个值
array_push($color, "red", "green", "blue");

// 打印数组
print_r($color);
?>

The output result is:

Array
(
    [0] => red
    [1] => green
    [2] => blue
)

As you can see, three values ​​​​were successfully added to the array, Each value is at the end of the array.

In addition to using the array_push() function, we can also use the assignment method to add values ​​to the array. For example, we can use $color[] = "red" to add the value "red" to the end of the array $color. However, this method is not very convenient if we need to add multiple values ​​to the array. In this case, the array_push() function can make the code more concise and easier to understand.

In summary, array_push() is a very convenient function in PHP that can help us add one or more values ​​to an array. Its use is very simple, just pass the array as the first parameter and the value to be added to the array as the second parameter. If you want to add multiple values, just do it by passing multiple parameters in the function. In actual development, we need to use the array_push() function flexibly to make our code more concise and easier to maintain.
