PHP Indexed Arrays

In PHP, an indexed array is an array where each element is assigned a numerical index starting from zero. Indexed arrays are the most common type of arrays used in PHP.

Here’s an example of how to create and access an indexed array:

// Create an indexed array
$fruits = array("apple", "banana", "orange");

// Access elements in the array
echo $fruits[0]; // Output: apple
echo $fruits[1]; // Output: banana
echo $fruits[2]; // Output: orange

In this example, we create an array of fruits with three elements and assign it to the variable $fruits. We then use the index number to access each element in the array and output its value using echo.

You can also add elements to an indexed array dynamically using the [] syntax:

// Create an empty indexed array
$numbers = array();

// Add elements to the array
$numbers[] = 1;
$numbers[] = 2;
$numbers[] = 3;

// Access elements in the array
echo $numbers[0]; // Output: 1
echo $numbers[1]; // Output: 2
echo $numbers[2]; // Output: 3

In this example, we create an empty indexed array called $numbers and then add three elements to it using the [] syntax. We then use the index number to access each element in the array and output its value using echo
