How to add members to an array in php

PHP is a globally popular development language that is often used to develop web applications. In PHP, array is a very important and commonly used data type. Arrays can store multiple values ​​and perform operations. This article will show you how to add members to an array in PHP.

There are two ways to add array members in PHP: using the array_push() function and using direct assignment statements. The usage of these two methods is introduced below.

Use the array_push() function

The array_push() function can add one or more elements to the end of the array. This function requires two parameters. The first parameter is the array to which the elements are to be added, and the second parameter can be one or more elements to be added.

For example, the following code creates an empty array and then uses the array_push() function to add three elements to the array:

$my_array = array();
array_push($my_array, "apple", "banana", "orange");

Now, the $my_array array contains three string elements: "apple ","banana","orange". You can use a for loop to iterate over the array and access the elements:

for ($i = 0; $i < count($my_array); $i++) {
    echo $my_array[$i] . "<br>";
}

This will output:

apple
banana
orange

Use direct assignment statement

You can also use direct assignment statement to PHP Add elements to an array. This method is simpler than using the array_push() function, but only one element can be added. The following is an example of adding elements to an array using a direct assignment statement:

$my_array = array("apple", "banana");
$my_array[] = "orange";

Now, the $my_array array contains three string elements: "apple", "banana", "orange". Likewise, you can use a for loop to iterate through the array and access the elements: There are two ways to add members: using the array_push() function and using direct assignment statements. Although both methods can be used for this operation, the array_push() function is suitable for adding multiple elements to an array, while the direct assignment statement is more suitable for adding a single element to an array. Please choose the method that suits your code.
