Why's the big red stack trace error box still appearing when I use register_shutdown_function and set_error_handler?
<p>I use both of them to handle all sorts of errors, even Fatal Errors. My callback functions get called when an error happens, but I keep getting this big red error info box with the stack trace. My visitors shouldn't see that at all! never!</p>

<p>To be sure, both callbacks return true. Actually that should disable the PHP's default error processing, right? But it doesn't.</p>

<p>I have a MAMP environment on my mac. Maybe there's some strange configuration that forces this error box no matter what I do?</p>
