Are there any best practices to follow when working with references in PHP?

When working with references in PHP, it is important to be cautious as they can lead to unexpected behavior if not used correctly. To avoid any issues, it is recommended to follow best practices such as clearly documenting where references are being used, avoiding unnecessary references, and being mindful of potential side effects when modifying referenced variables. 

// Example of using references in PHP with best practices
$originalValue = 10;

// Passing variable by reference to a function
function incrementValue(&$value) {
    $value++;
}

incrementValue($originalValue);
echo $originalValue; // Output: 11
