PHP Indexed Arrays
An indexed array is an array where each element is assigned a numeric index. The index starts from 0 by default and increments by 1 for each subsequent element. Indexed arrays are typically used to store a simple list of items such as numbers, strings, or other data types.
Access Indexed Arrays
To access an element in an indexed array, you use its index inside square brackets:
Example
<?php
$fruits = ["Apple", "Banana", "Cherry"];
echo $fruits[0]; // Outputs: Apple
echo $fruits[1]; // Outputs: Banana
?>
Change Value
You can change an element’s value by specifying its index:
Example
<?php
$fruits = ["Apple", "Banana", "Cherry"];
$fruits[1] = "Blueberry"; // Changes the element at index 1 to "Blueberry"
var_dump($fruits);
?>
Loop Through an Indexed Array
You can loop through an indexed array using a foreach loop:
Example
<?php
$fruits = ["Apple", "Banana", "Cherry"];
foreach ($fruits as $fruit) {
echo $fruit . "<br>";
}
?>
