Easy to send email samples using the SMTP class in PHP

When you are still in the tangle php built-in mail () function can not send mail, then you are very lucky now, this article can help you!

PHP uses the SMTP class to send mail is very good, I used a long time, basically did not have a problem. This blog backstage, when the blogger reply to the message, will automatically send a new reply to users of the message is also used in this method to achieve.

The way the SMTP class sends mail is actually very simple and stable, and the class is already written by someone else, and you just need to call on the line. A few lines of simple configuration can send mail, is not very looking forward to try it!

email.class.php file

The code is as follows

SMTP class cannot send message resolution

Accidentally found my website background automatically send mail function can not use, reported this error:

Trying to smtp.126.com:25 Error:cannot connenct to relay host smtp.126.com Error: () error:cannot send email to Web@daix Iaorui.com State

Probably means: Unable to connenct the relay host smtp.126.com error: () error £ º Unable to send e-mail to web@daixiaorui.com

After finding more than n data on the Internet, we finally found the solution, not the SMTP class problem, but the Linux configuration. The Fsockopen function is disabled by the php.ini of the server.

Open the space under the php.ini file, Linux space can generally be customized php.ini, so the root directory will generally have this file.

There are two places where this function may be disabled:

1. Allow_url_fopen = on view equals after on, and if off, the function is disabled

2. disable_functions = Fsockopen Pfsockopen (This is my case) this should remove the front "fsockopen". To make it into: Disable_functions = Pfsockopen

After you have changed, save and refresh the page, you will find that you can successfully use the SMTP class to send e-mail messages under Linux. Thanks to the method of sharing friends, the problem has finally been solved.
