Use the mail function in php to send emails with attachments

Mail function, mail syntax: mail (to, subject, message, headers, parameters) to specifies the subject of the email specified by the mail recipient subject. This parameter cannot include the... mail function to send emails.

Syntax: mail (to, subject, message, headers, parameters)

To specifies the recipient of the email

Subject specifies the subject of the email. This parameter cannot contain any line breaks

Message specifies the message to be sent

Headers specifies additional headers, such as From, Cc, and Bcc.

Parameters specifies additional parameters for the sendmail program.

The main problem encountered was garbled code. at the beginning, some clients were good at receiving emails (such as QQ mail, which is estimated to contain the automatic identification code). some of them were not foxmail, and the ipad showed garbled code, set the mail headers correctly. The following is a perfect example without garbled characters.

Configuring the PHP. ini file in php involves two steps:

1. first, find the place where you put all the PHP, Apache, and MySQL files. in the PHP folder, you can find a file: php. ini, open it, find the mail function, and change the original configuration code to the following (only for windows ):

[mail function] ; For Win32 only. SMTP =smtp.sohu.com     mtp_port=25 ; For Win32 only.

Sendmail_from = fill in the full name of your email.

The setting here is the sohu email server. if you use a 163 email address, it is set to smtp.163.com.

2. search for php. ini, select the php that is not a shortcut. ini, which should be in C/WINDOWS, open it, modify it as above, save it, remember to restart the Apache server after setting, and then the mail () function can be used, the sample code is as follows:

The above function cannot contain attachments. the code is as follows:

Sample code. some variables require the context. the code is as follows:

 setToaddr($this->temp['receipt_address']);$m->setTopic($this->temp['mail_title']);$m->setContent($this->temp['mail_content']);$m->setFromaddr($_SESSION['user']['name'] . ' <' . $_SESSION['user']['name'] . '@' . SystemDomain . '>');$m->setDomain('@' . SystemDomain);$m->setCc($this->temp['cc_address']);$m->setAttach(PATH . '/temp/' . $this->temp['attachment_file']);$m->send();?>

Advantage: easy to use a simple function

Disadvantage: php. ini is required to support this function. if some servers do not support this function and cannot change the environment, it will not work and will always be unstable, and sometimes it will not work.
