What are the best practices for handling dynamic function changes in PHP applications, such as in the case of an IRC bot?

When dealing with dynamic function changes in PHP applications, such as in an IRC bot, it is best to use a configuration file or database to store the function names and mappings. This allows for easy updating and modification without having to change the code itself. Additionally, using a function_exists() check before calling a dynamic function can help prevent errors if a function is not found. 

// Example of handling dynamic function changes in an IRC bot

// Configuration file or database storing function mappings
$function_mappings = [
    'command1' => 'function1',
    'command2' => 'function2',
    // Add more mappings as needed
];

// Check if the function exists before calling it
if (function_exists($function_mappings[$command])) {
    $function_to_call = $function_mappings[$command];
    $function_to_call();
} else {
    // Handle case where function is not found
    echo "Function not found for command: $command";
}

// Example functions
function function1() {
    echo "Function 1 called";
}

function function2() {
    echo "Function 2 called";
}
