Are there any best practices for controlling loops and user interactions in PHP?

When dealing with loops and user interactions in PHP, it is important to ensure that the code is structured in a way that prevents infinite loops and handles user input correctly. One best practice is to use conditional statements to control the flow of the loop and validate user input to prevent unexpected behavior. 

// Example of controlling a loop with user input
$continue = true;

while($continue) {
    // Prompt user for input
    $input = readline("Enter 'exit' to quit: ");

    // Check if user wants to exit
    if($input === 'exit') {
        $continue = false;
    }
}
