What are the best practices for accessing the first value of an array in PHP?

To access the first value of an array in PHP, you can use the array index 0. This will retrieve the value at the first position of the array. It is important to check if the array is not empty before trying to access the first value to avoid errors. 

// Example of accessing the first value of an array
$array = [10, 20, 30, 40, 50];

if (!empty($array)) {
    $firstValue = $array[0];
    echo $firstValue; // Output: 10
} else {
    echo "Array is empty.";
}
