Move list item in list array item to top php

In JavaScript, we can access an array element as in other programming languages like C, C++, Java, etc. Also, there is a method called splice() in JavaScript, by which an array can be removed or replaced by another element for an index. So to move an array element from one array position to another we can splice() method or we can simply use array indexing ([]).

These are the following ways to solve this problem:

Using for loop

In this approach, we are using a for loop for moving an array element from one position to another one.

Example: This example shows the implementation of the above-explained approach.

javascript

let arr = [ "C++" , "Java" , "JS" , "Python"

Original array: C++ ,Java ,JS ,Ruby ,Python After move: C++ ,Ruby ,Java ,JS ,Python

`let arr = [`0`let arr = [`1

`let arr = [`2

`let arr = [`3

Original array: C++ ,Java ,JS ,Ruby ,Python After move: C++ ,Ruby ,Java ,JS ,Python

1`let arr = [`5

Original array: C++ ,Java ,JS ,Ruby ,Python After move: C++ ,Ruby ,Java ,JS ,Python

Output

Original array: C++,Java,JS,Python After move: C++,Python,Java,JS

Using splice() function

In this approach, we are using splice() function. If the given posiiton is less then zero then we will move that element at the end of the array. If it is greater than 0 then we will move the element in between the array, that is how we move our element according to the index.

Example: This example shows the implementation of the above-explained approach.

javascript

let arr = [ let arr = [`8, "C++"0, "C++"2"C++"`3

let arr = [`0"C++"5, "C++"`7

Original array: C++ ,Java ,JS ,Ruby ,Python After move: C++ ,Ruby ,Java ,JS ,Python

`, `2

`, `3

, `4 , `5

let arr = [`0, `7

`let arr = [`2

, `4 "Java"`0

let arr = [`0"Java"`2

`let arr = [`2

"Java"`4 "Java"`5

let arr = [`0"Java"`7

let arr = [`0, 4 , `0

, `1, `2

`let arr = [`0`let arr = [`2

`let arr = [`2

`, `6

Original array: C++ ,Java ,JS ,Ruby ,Python After move: C++ ,Ruby ,Java ,JS ,Python

1`let arr = [`5

Original array: C++ ,Java ,JS ,Ruby ,Python After move: C++ ,Ruby ,Java ,JS ,Python

Output

Original array: C++ ,Java ,JS ,Ruby ,Python After move: C++ ,Ruby ,Java ,JS ,Python

Using slice(), concat(), and spread operator

In this approach, we are using slice(), concat(), and spread operator. we are craeting the array from the index 0 to the index where that element(that will be moved) is present and the inserted new element and the remaining elements.

Example: In this example, we will use slice(), concat(), and spread operator.

Javascript

`"JS"`0

`"JS"`1

`"JS"`2

"JS"`3"JS"`4

"JS"`3"JS"`6

"JS"`7"JS"`8

Original array: C++ ,Java ,JS ,Ruby ,Python After move: C++ ,Ruby ,Java ,JS ,Python

`, `0

How do you move elements to the top of an array in PHP?

array_unshift() prepends passed elements to the front of the array . Note that the list of elements is prepended as a whole, so that the prepended elements stay in the same order. All numerical array keys will be modified to start counting from zero while literal keys won't be changed.

How do you add an item to the top of an array in PHP?

Using array_unshift() function: The array_unshift() function is used to add one or more elements at the beginning of the array.

How do you add elements to the front of an array in PHP?

The array_unshift() function inserts new elements to an array. The new array values will be inserted in the beginning of the array. Tip: You can add one value, or as many as you like. Note: Numeric keys will start at 0 and increase by 1.
