PHP cannot access protected property error

Question

I can't see anything wrong with this, but I see the above exception occasionally in the logs. What's wrong?

PHP Fatal error: Cannot access protected property Exception::$message in /web/index.php on line 23

On line 23 I have,

echo '<?xml version=\'1.0\'?><error-response status="error"> <message><![CDATA['.$e->message.']]></message> </error-response>'; 

Answer 1

Use $e->getMessage() instead of $e->message because message is a protected property :)
