Does trigger_error () in PHP become obsolete for something better in PHP5?

Question

I used this when I wanted to cause errors in PHP based on the background of PHP4. Note. To handle these errors, I had my own set_error_handler().

if ($error) {
    trigger_error('Sorry, error has occured');
}

I cannot remember where, but once someone told me that I should “use exceptions”. Since I am reviewing a lot of my old code, I decided it was time to get some good advice on my error handling.

Now that I'm using PHP5 (and a little smarter than when the old code was written), is my trigger_error()just the old way to do something, and if so, what is the best way to handle the error in PHP5?
