Is it best practice to ignore PHP warnings or to prevent them from occurring in the first place?

It is best practice to prevent PHP warnings from occurring in the first place rather than ignoring them. Ignoring warnings can lead to unexpected behavior and potential issues in your application. To prevent warnings, you can use error_reporting() function to set the error reporting level and handle errors gracefully using try-catch blocks. 

// Set the error reporting level to exclude warnings
error_reporting(E_ALL & ~E_WARNING);

try {
    // Your code that may cause warnings
} catch (Exception $e) {
    // Handle any exceptions or errors
    echo 'An error occurred: ' . $e->getMessage();
}
