An array is a data structure that stores a collection of elements, usually of the same type, in a single variable. These elements can be numbers, strings, objects, or even other arrays. Arrays allow you to store and access multiple values in an ordered manner, using indexes.
Creating an Array:
You can create arrays using the array() function or the short array syntax [].
<?php
// Using array() function
$fruits1 = array("Apple", "Banana", "Orange");
var_dump($fruits1);
// Using short array syntax
$fruits2 = ["Apple", "Banana", "Orange"];
var_dump($fruits2);
Accessing Array Elements:
You can access array elements by referring to their index.
<?php
$fruits = ["Apple", "Banana", "Orange"];
echo $fruits[0]; // Outputs: Apple
Adding Elements to an Array: Use array_push() or simply assign a value to a new index to add elements to an array.
<?php
$fruits = ["Apple", "Banana", "Orange"];
// Adding using array_push()
array_push($fruits, "Grapes");
// Adding using array index
$fruits[] = "Mango";
var_dump($fruits);
Removing Elements from an Array: You can remove elements from an array using unset() or array functions like array_pop() and array_shift().
<?php
$fruits = ["Apple", "Banana", "Orange"];
// Remove last element
array_pop($fruits);
// Remove first element
array_shift($fruits);
// Remove element by index
unset($fruits[1]); // Removes Banana
var_dump($fruits);
Iterating Over an Array: Loop through an array using foreach().
<?php
$fruits = ["Apple", "Banana", "Orange"];
foreach ($fruits as $fruit) {
echo $fruit;
}
Merging Arrays: Combine arrays using array_merge().
<?php
$fruits = ["Apple", "Banana", "Orange"];
$moreFruits = ["Pineapple", "Watermelon"];
$allFruits = array_merge($fruits, $moreFruits);
var_dump($allFruits);
Sorting Arrays: You can sort arrays with functions like sort(), rsort(), asort(), ksort(), etc.
<?php
$fruits = ["Apple", "Banana", "Orange"];
sort($fruits); // Sort in ascending order
var_dump($fruits);
