如果PHP脚本崩溃，则通过电子邮件报告

I have some php scripts for importing product feeds into a website. Sometimes those scripts crash (due to the "500 Internal Server Error", I believe) and I need to send a notification through e-mail.

Will it be sufficient to add a try catch to the existing code? Something like:

try {
[existing_code]
}

catch (customException $e) {
  echo $e->errorMessage();
  [e-mail_the_error]
}

Many thanks!
