Basically try-catch gives you the ability to handle errors outside a class or method scope, by the calling instance.
This comes in handy, if you are programming in an object orientated way and thus enables you to seperate error handling from the rest of your functionality.
Means, your methods do only the things, they are meant to do, without bothering to handling occuring errors.
Hope, that made things clearer.

Looks like I still didn't get it correctly:

try
{
   if (!send_confirmation_email($email, $subject, $content))

   {
       throw new Exception('Confirmation email is not sent');
   }

}
catch (Exception $e)
{

   send_email_with_error_to_admin($e, $content);
}

why am I getting both emails? I'm receiving confirmation email and email with error message - that I'm supposed to get if the first one is not sent for some reason?!?!?!?

thanks for any help.

what does this function [send_confirmation_email($email, $subject, $content)] return?

Cat, the other other white meat





function send_confirmation_email($to, $subject, $body)
{    
  $headers =    "MIME-Versin: 1.0\n" .
                 "Content-type: text/plain; charset=ISO-8859-1; format=flowed\n" .
                 "Content-Transfer-Encoding: 8bit\n" .
                            "Reply-To: Contact <lamp.lists@xxxxxxxxx>\n".
                 "From: Contact <lamp.lists@xxxxxxxxx>\n" .
                 "X-Mailer: PHP" . phpversion();
        
    mail($to, $subject, $body, $headers) or die(mysql_errno());
}

$body is "regular" confirmation text: "Thank you for subscribing. To activate your account klick on the following link..." etc.




function send_email_with_error_to_admin($e, $content)
{
  $error_message  = "Caught exception: " . $e->getMessage() . "\n";
  $error_message .= "Code : " . $e->getCode()."\n";
  $error_message .= "File : " . $e->getFile()."\n";
  $error_message .= "Line : " . $e->getLine()."\n";
  
    $to_email = "lamp.lists@xxxxxxxxx";
    $subject = "[Confirmation Error Report] ".$e->getMessage();
    $content .= "\n--------------------------------------------------------------------------------------------------\n\n";
    $content .= "Error Report:\n\n".$error_message;
    $content .= "\n--------------------------------------------------------------------------------------------------\n\n";
    
    send_confirmation_email($to_email, $subject, $content);
}
