What are some common pitfalls to avoid when developing interpreters for unconventional programming languages in PHP, and how can they be mitigated?

Issue: One common pitfall when developing interpreters for unconventional programming languages in PHP is not properly handling errors and exceptions. To mitigate this, it is important to implement robust error handling mechanisms to catch and handle any errors that may occur during the interpretation process. 

try {
    // Interpret the unconventional programming language code here
} catch (Exception $e) {
    // Handle the error or exception gracefully
    echo "An error occurred: " . $e->getMessage();
}
