What are the best practices for handling function return values in PHP?

When handling function return values in PHP, it is important to check for potential errors or false returns to prevent unexpected behavior in your code. One best practice is to use conditional statements to validate the return value before using it further in your code. Additionally, it is recommended to assign the return value to a variable for easier manipulation and debugging. 

// Example of handling function return values in PHP
$result = myFunction(); // Call the function and store the return value in a variable

if ($result !== false) { // Check if the return value is not false
    // Proceed with using the return value
    echo "Function returned: " . $result;
} else {
    // Handle the case where the function return value is false
    echo "Error: Function returned false";
}

function myFunction() {
    // Function logic here
    return "Hello, World!"; // Return a sample value
}
