Array push and pop in PHP; In this tutorial, you will learn how to use the array push and array pop method in PHP.
Array push and pop are two important functions in PHP that allow you to add or remove elements from an array. These operations are essential for manipulating arrays, which are a fundamental data structure in PHP used for storing collections of values of the same type.
The array_push() function is used to add one or more elements to the end of an array. It takes the array as the first argument, followed by one or more elements to add to the end of the array. The function modifies the original array and returns the new length of the array.
The array_pop() function, on the other hand, removes the last element from an array and returns it. This function also modifies the original array, reducing its length by one.
Both of these functions can be used in a wide range of scenarios, such as adding or removing elements from a list of items, maintaining a stack or queue data structure, or processing data in a specific order.
It is important to note that these functions should be used with caution, as they can modify the original array and may have unintended side effects if used improperly. Therefore, it is important to carefully consider the requirements of the project and the behavior of the functions when using them to add or remove elements from an array in PHP.
Array Push, POP PHP
Arrays are an important data structure in PHP that allow you to store and manipulate a collection of values of the same type. One of the most common operations performed on arrays is adding and removing elements from them. In PHP, the array_push() and array_pop() functions are used to add and remove elements from the end of an array, respectively.
- PHP array_push() function
- PHP array_pop() function
PHP array_push() function
The array_push() function adds one or more elements to the end of an array. It takes two arguments: the first argument is the array to which the elements will be added, and the remaining arguments are the elements to be added.
Syntax of array_push() function
array_push(array, value1, value2, …)
Example – add/insert/push elements/items in an array PHP
In this example, we have one array “array(“PHP”, “laravel”, “codeigniter”)”, it contains value like (“PHP”, “laravel”, “codeigniter”). If we want to add/push one or more values in the array. You can add/push the values into array see below examples:
Here we will add new values like(“WordPress”,”bootstrap”,”HTML”) in existing array using PHP array_push() function:
<?php
$array = array("php", "laravel", "codeigniter");
//before adding new values
echo "Before add the value:- ";
print_r($array); echo "<br>";
//add elements/values in array
array_push($array,"wordpress","bootstrap","html");
//after adding a new values
echo "After add the value:- ";
print_r($array);
?>
PHP array_pop() function
The array_pop() function removes the last element from an array and returns it. It takes one argument, which is the array from which the element will be removed.
Syntax of PHP array_pop() function
array_pop(array);
Example – Delete/Remove elements/items from an array PHP
In this example, we have one array “array(“PHP”, “laravel”, “codeigniter”,”bootstrap”)”, it contains value like (“PHP”, “laravel”, “codeigniter”,” bootstrap “). If we want to remove/delete elements in the array. You can removes/deletes the elements/values into array see below examples:
<?php
$array = array("php", "laravel", "codeigniter","bootstrap");
//before remove elements array
echo "Before add the value:- ";
print_r($array); echo "<br>";
//remove elements from array
array_pop($array);
//after remove elements from array
echo "After add the value:- ";
print_r($array);
?>
It is important to note that both array_push() and array_pop() functions modify the original array. If you need to add or remove elements from the beginning of an array, you can use the array_unshift() and array_shift() functions, respectively.
