PHP array push: How to Add Elements to Array in PHP
Add elements/items to an array in PHP; In this tutorial, we would like to share with you how to add or push the items/elements to array in PHP.
- Using array_push() with keys in PHP
- Adding elements to an associative array using array_push() in PHP
- Adding elements to a multidimensional associative array in PHP
- Adding elements to a multidimensional array in PHP
- Pushing an array into a multidimensional array in PHP
- Appending one array to another in PHP
How to Add Elements to Array in PHP
Using the array_push(), you can add elements to an array in PHP.
The array_push() function is used to add one or more elements to the end of an array.
The syntax of array_push() is as follows:
array_push(array, value1, value2, …)
The first parameter, array , is the name of the array to which you want to add elements. The second parameter and subsequent parameters are the values that you want to add to the array.
Example 1 of Add Elements to Array using array_push() in PHP
Let’s consider an example where you have an array of colors, and you want to add a few more colors to the array. Here is the code to do this:
The code creates an indexed array called $colors with three initial elements: “red”, “green”, and “blue”. It then uses the array_push() function to add two more elements, “yellow” and “orange”, to the end of the array.
Finally, the code uses the print_r() function to display the contents of the $colors array, including the newly added elements, in a human-readable format.
So, when the code is executed, it will output the following:
Array ( [0] => red [1] => green [2] => blue [3] => yellow [4] => orange )
This shows that the two new elements (“yellow” and “orange”) have been successfully added to the end of the $colors array.
Example 2 of array push key value pair php using array_push
Sure, here’s an example of using array_push in PHP to add a key-value pair to an array:
// Define an empty array $myArray = array(); // Add a key-value pair to the array using array_push array_push($myArray, array("key" => "value")); // Print the array to verify the key-value pair was added print_r($myArray);
This PHP code is creating an empty array and then adding a key-value pair to it using the array_push function. Finally, it prints the array using the print_r function to confirm that the key-value pair was added successfully.
- $myArray = array(); creates an empty array called $myArray .
- array_push($myArray, array(«key» => «value»)); adds an element to the end of $myArray . The element is an array with a single key-value pair, where the key is «key» and the value is «value» .
- print_r($myArray); prints the contents of $myArray , including the newly added key-value pair. The print_r function is used to print the array in a human-readable format.
So, after running this code, the output would be something like:
Array ( [0] => Array ( Php array push all => value ) )
This shows that $myArray now contains a single element, which is an array with a key-value pair of «key» => «value» .
Example 3 of add element to multidimensional array using array_push
Sure, here’s an example of adding an element to a multidimensional array using array_push() function in PHP:
The above code defines a multidimensional array called $myArray , which contains two inner arrays, each containing three elements.
Then, the array_push() function is used to add a new element “grape” to the first inner array of $myArray . The array_push() function adds an element to the end of an array and returns the new number of elements in the array.
Finally, the updated $myArray is displayed using the print_r() function, which prints the entire contents of the array, including all the nested arrays and their elements.
So, after executing this code, the output will be:
Array ( [0] => Array ( [0] => apple [1] => banana [2] => orange [3] => grape ) [1] => Array ( [0] => carrot [1] => pepper [2] => onion ) )
Example 4 of How to push array in multidimensional array using array_push
Sure, here’s an example of how to use the array_push() function in PHP to push an array into a multidimensional array:
// Initialize the multidimensional array $multiArray = array( array('apple', 'banana', 'orange'), array('carrot', 'broccoli', 'pepper') ); // Define the array to push into the multidimensional array $newArray = array('grape', 'kiwi', 'pineapple'); // Use array_push() to add the new array to the end of the multidimensional array array_push($multiArray, $newArray); // Print the updated multidimensional array print_r($multiArray);
- array() function is used to initialize the multidimensional array $multiArray with two nested arrays, each containing three string elements.
- The $newArray is defined as an array containing three string elements, which will be added to the multidimensional array.
- array_push() is a built-in PHP function used to add elements to the end of an array. Here, it’s used to add $newArray to $multiArray .
- The print_r() function is used to output the contents of the $multiArray array, which now includes the added $newArray at the end.
The output of this code will be:
Array ( [0] => Array ( [0] => apple [1] => banana [2] => orange ) [1] => Array ( [0] => carrot [1] => broccoli [2] => pepper ) [2] => Array ( [0] => grape [1] => kiwi [2] => pineapple ) )
PHP append one array to another | PHP push array into an array
Now, you will take example of push one array to another array or push array into an array without using array_push() function.
Add one array into another array in PHP:
Conclusion
Through this tutorial, you have learned how to add values in array PHP, PHP array push with key, PHP add to an associative array, PHP add to the multidimensional array, array push associative array PHP, PHP array adds key-value pair to an existing array with examples.

array_push
array_push() использует array как стек, и добавляет переданные значения в конец массива array . Длина array увеличивается на количество переданных значений. Имеет тот же эффект, что и выражение:
Замечание: Вместо использования array_push() для добавления одного элемента в массив, лучше использовать $array[] = , потому что в этом случае не происходит затрат на вызов функции.
Замечание: array_push() вызовет предупреждение, если первый аргумент не является массивом. Это отличается от поведения конструкции $var[], в случае которой будет создан новый массив.
Список параметров
Первое значение, добавляемое в конец массива array .
Возвращаемые значения
Возвращает новое количество элементов в массиве.
Примеры
Пример #1 Пример использования array_push()
$stack = array( «orange» , «banana» );
array_push ( $stack , «apple» , «raspberry» );
print_r ( $stack );
?>?php
Результат выполнения данного примера:
Array ( [0] => orange [1] => banana [2] => apple [3] => raspberry )

How to add elements to an array in PHP?
In this short tutorial, we look at how to add PHP elements to an array, the different methods to do so, and their use-cases.
However, in case you are here only for the solution use this link.
Table of Contents — PHP add to array
PHP: Add to array or append to array:
Appending or adding an element into an array is a commonly used method not only in PHP but in other programming languages as well. However, adding elements to an array in PHP can be done with a handful of methods.
These methods vary based on their use cases. If you are looking to add an element at the end of the array, you can look at the two methods.
If you are looking to add elements to the beginning of the array, the array_unshift method can be used.
Add to array using square brackets:
The square bracket method to PHP add to array is one of the most commonly used methods.
Because of its efficiency, most programmers recommend the use of this method. In comparison to the other methods, it adds to an array without the overhead of calling a function.
But the downside is that it can only add one argument at a time.
Syntax of Square Bracket method
Here array refers to the original array you are looking to append.
element is the value you are looking to add to the array.
Code and Explanation
$skillset= array( 'JavaScript', 'Python', 'C++' ); //Now, let's add to the array $skillset[] = 'PHP'; //Output var_dump($skillset);
Output
array(4) < [0]=>string(10) "Javascript" [1]=> string(6) "Python" [2]=> string(3) "C++" [3]=> string(3) "PHP" >
As you can see, the above code can be used in PHP to add to array. But despite its efficiency, adding more than one element would be a hassle while using this method.
Using the array_push method:
The array_push is another inbuilt function that can be used in PHP to add to arrays. This method can be used to add multiple elements to an array at once.
Syntax of array_push
array_push($array , value1, value2, . value(n-1))
Parameters:
array — Required, this parameter specifies the array you are looking to append
value1 — The value that you are looking to add to the array
Return Values
The array_push returns the number of elements in the array.
Code and Explanation:
$skillset= array( 'JavaScript', 'Python', 'C++' ); //Now, let's add to the array array_push($skillset, 'PHP', 'HTML', 'CSS'); var_dump($skillset);
Output
array(6) < [0]=>string(10) "Javascript" [1]=> string(6) "Python" [2]=> string(3) "C++" [3]=> string(3) "PHP" [4]=> string(4) "HTML" [5]=> string(3) "CSS" >
As you can see the array_push in PHP adds to array the passed elements.
However, It is important to remember that the function returns the length and not the appended array. This is important because assigning the function to a variable and printing it would not return your desired output.
The below code explains the same.
$skillset= array( 'JavaScript', 'Python', 'C++' ); //Now, let's add to the array $new_array = array_push($skillset, 'PHP', 'HTML', 'CSS'); echo($new_array);
This code outputs 6 which is the length of the updated array that you desired.
PHP: Add to array — Limitations and Caveats:
- Remember that the square bracket is more efficient and should always be chosen when you are looking to add to an array.
- While using the square bracket method, ensure that the name of the existing array is entered correctly because if the name passed is wrong a new array would be created.
- The array_push returns a warning when the array you are looking to add to does not exist.
