What is the recommended approach for reading values from an array in PHP?

When reading values from an array in PHP, it is recommended to use the square bracket notation to access specific elements in the array. This notation allows you to specify the index of the element you want to retrieve. Additionally, you can use functions like isset() to check if a specific index exists in the array before attempting to access it to avoid errors.

// Sample array
$fruits = array("apple", "banana", "orange");

// Accessing the first element in the array
$firstFruit = $fruits[0];
echo $firstFruit; // Output: apple

// Checking if a specific index exists before accessing it
if(isset($fruits[1])) {
    $secondFruit = $fruits[1];
    echo $secondFruit; // Output: banana
}
