Finding a substring into a string

Matth_S

Hi,

I try to check out the mail with a delivery error in my inbox.
So I wrote a php page which connects to the pop server and gets the received messages.

I want to get both the email address to which I couldn't deliver the message and the error type that is returned (for example :
-550 5.1.1 User unknown
-550 : Recipient address rejected: User unknown
-550 MAILBOX NOT FOUND

etc

To get the error part of the message, I made a list of the error types , I get the body of each email and I check if it contains one of the errors among my error list :

while($error_array=each($error)){
  if(substr_count($body,$error_array['value'])>0){
   /* the rest of the code gets the email address and inserts it in the database*/
 } // end if
} // end while

$error being an array in which I load each error type from the database.

It works well for all error types but 3 :
- 550 5.1.1 ... User unknown
- 550 : Recipient address rejected: User unknown
- 550 5.1.1 ... Unknown user

I don't know why those 3 errors can't be detected with my code while it works with the other.

What is different in those 3 errors from other, I do not know

Thanks for your answer

I just tried the function you suggested (in the topic mentioned) ; but I still have the same problem.

some debugging?

echo '<plaintext>';
while($error_array=each($error)){
  if(substr_count($body,$error_array['value'])>0){
   /* the rest of the code gets the email address and inserts it in the database*/
 } // end if
  else {
    echo '-'.$error_array['value'].'-'.$body."-\r\n\r\\r\n\r\n";
  }
} //

output?

Thanks for your answer !

Ok the problem is solved (thanks to your debugging advice).

In fact, there was the email address of the addressee inside the error message ; but as it was between < > , it wasn't displayed without the plain text command.
