Are there any best practices or conventions to follow when handling arrays with only one value in PHP?

When handling arrays with only one value in PHP, it is a good practice to check if the array has only one element and access that element directly rather than looping through the array. This helps to improve performance and readability of the code. 

// Check if the array has only one value and access it directly
if (count($array) == 1) {
    $value = reset($array);
    // Use $value for further processing
}
