[PHP] Re: PHP Access Violation using PEAR::Mail_smtp
So, I found a solution to my problem. I still do not know what was causing the PHP Access Violation errors, but I have an idea, which I will relate in this message. As many suggested, I have pared down my mail sending class by rewriting it down to about 250 lines of code. Previously, the PEAR::Mail::smtp class had much fewer lines of code, but if you count all of the other files it had to include, then it was a whopping amount of code. The difference here is that I am only using one class now to send mail, whereas the PEAR::Mail::smtp class was using about 5 different classes. Let me walk you through them. Mail::smtp included and extended the Mail class. The Mail class included and extended the PEAR class. The send() method of Mail::smtp included the Net::SMTP class and created an object of that class. The Net::SMTP class included the PEAR and Net::Socket classes (and optionally checked for and included the Auth::SASL class). The Net_SMTP() contstructor created a Net::Socket object. The Net::Socket class included and extended the PEAR class. So, in all, that's about 5 classes that Mail::stmp needed. Once I got it down to one class, the Access Violations disappeared. So, here's what I think was happening with the classes based on some of the information I have been told. I've been told that the Access Violation errors are probably caused when PHP tries to access a space of memory that it doesn't have permission to access. From this, I'm gathering that the sheer number of classes needed and objects and variables created confused PHP so that it wasn't sure what pointers pointed to the correct space in memory. (Again, I'm out on a limb with this guess.) Because the pointer lost its space in memory (I'm guessing that's what happened), PHP tried to access a space that it either no longer had permission to access or it never had permission to access. Make sense? I'm sharing this here because several people expressed an interest in knowing how it got resolved. -- Regards, Ben Ramsey http://benramsey.com http://www.phpcommunity.org/wiki/People/BenRamsey -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: PHP Access Violation using PEAR::Mail_smtp
Let me point something out here: I was a goof and had an authentication setting wrong. When I changed it back to LOGIN, it sends e-mail just fine. So, all is well... sort of. Every 3rd or 4th run of the script still generates the Access Violation message. However, since it happens intermittently, it makes it a pain in the rear to track down. DVD> Also, you don't need a mailserver on localhost to use mail() I'm on Windows Server 2003... Here's the error I get when I use mail() and no SMTP authentication: Code: mail("[EMAIL PROTECTED]","This is a test","This is the message"); Error: Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in E:\path\to\test.php on line 5 When I explicitly set the correct mail server with ini_set(), I get: Warning: mail() [function.mail]: SMTP server response: 550 Relaying is prohibited in E:\path\to\test.php on line 6 This is why I've gone with using the PEAR class Mail_smtp. It seems the easiest thing to use without having to write a whole lot of socket connection code. -- Regards, Ben Ramsey http://benramsey.com http://www.phpcommunity.org/wiki/People/BenRamsey -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: PHP Access Violation using PEAR::Mail_smtp
Well, the reason noone replies I guess, is that noone knows.. I think your best bets are to echo the steps in the class, and find exactly what causes it to crash.. Also, you don't need a mailserver on localhost to use mail().. I use mail() with my ISP's SMTP server, and I'm on XP (same thing work on windows Me)..
