What are the best practices for accessing individual values in an array based on their position number in PHP?

When accessing individual values in an array based on their position number in PHP, it is important to ensure that the position number exists within the array to avoid errors. To do this, you can use the isset() function to check if the index exists before accessing it. Additionally, you can use a loop to iterate through the array and access each value individually based on its position number. 

$array = [10, 20, 30, 40, 50];

// Check if the index exists before accessing the value
if(isset($array[2])) {
    echo $array[2]; // Output: 30
}

// Accessing values in the array using a loop
foreach($array as $key => $value) {
    echo "Position $key: $value\n";
}
