How can PHP errors related to incorrect data types in form submissions be effectively troubleshooted?

To troubleshoot PHP errors related to incorrect data types in form submissions, you can use PHP's built-in functions like `is_numeric()` or `is_string()` to validate the data type before processing it. You can also use type casting functions like `(int)` or `(string)` to explicitly convert the data to the correct type. 

// Example code to validate and process form submission data
if(isset($_POST['age']) && is_numeric($_POST['age'])) {
    $age = (int)$_POST['age'];
    // Process the age data here
} else {
    echo "Age must be a valid number.";
}
