Отправка почты средствами PHP
Работая над проектом, мне пришлось создать специфичную «анкету соискателя» в котором надо была отправлять всю анкету на указные за ране e-mail адрес, и я сразу же вспомнил про PHP функцию mail().
bool mail ( string to, string subject, string message [, string additional_headers [, string additional_parameters]]) - E-mail получателя
- Заголовок письма
- Текст письма
- Дополнительные заголовки письма
- Дополнительные параметры командной строки
- true, если письмо было принято к доставке
- false, в противном случае.
Простейший пример
Перейдем к более сложному примеру
Текст письма 1-ая строчка 2-ая строчка '; $headers = "Content-type: text/html; charset=windows-1251 \r\n"; $headers . ; $headers .= "Reply-To: reply-to@example.com\r\n"; mail($to, $subject, $message, $headers); ?> В начале мы определяем кому адресовано письмо, за это отвечает переменная &to, если же получателей несколько человек, то записываем через запятую адреса эл. почты.
Переменные $subject и $message, не буду описывать, это и так понятно.
- В первой строчке ми определяем ты отправляемого письма-HTML и кодировку windows-1251.
- В 2-ом мы указываем от кого пришло письмо.
- В 3-ем указываем e-mail адрес, для ответа на письмо.
А теперь самое интересное отправка письма c вложением (attachment)
$subject = "тема письма"; $message ="Текст сообщения"; // текст сообщения, здесь вы можете вставлять таблицы, рисунки, заголовки, оформление цветом и т.п. $filename = "file.doc"; // название файла $filepath = "files/file.doc"; // месторасположение файла //исьмо с вложением состоит из нескольких частей, которые разделяются разделителем $boundary = "--".md5(uniqid(time())); // генерируем разделитель $mailheaders = "MIME-Version: 1.0;\r\n"; $mailheaders .="Content-Type: multipart/mixed; boundary=\"$boundary\"\r\n"; // разделитель указывается в заголовке в параметре boundary $mailheaders . ; $mailheaders .= "Reply-To: $user_email\r\n"; $multipart = "--$boundary\r\n"; $multipart .= "Content-Type: text/html; charset=windows-1251\r\n"; $multipart .= "Content-Transfer-Encoding: base64\r\n"; $multipart .= \r\n; $multipart .= chunk_split(base64_encode(iconv("utf8", "windows-1251", $message))); // первая часть само сообщение // Закачиваем файл $fp = fopen($filepath,"r"); if (!$fp) < print "Не удается открыть файл22"; exit(); >$file = fread($fp, filesize($filepath)); fclose($fp); // чтение файла $message_part = "\r\n--$boundary\r\n"; $message_part .= "Content-Type: application/octet-stream; name=\"$filename\"\r\n"; $message_part .= "Content-Transfer-Encoding: base64\r\n"; $message_part .= "Content-Disposition: attachment; filename=\"$filename\"\r\n"; $message_part .= \r\n; $message_part .= chunk_split(base64_encode($file)); $message_part .= "\r\n--$boundary--\r\n"; // второй частью прикрепляем файл, можно прикрепить два и более файла $multipart .= $message_part; mail($to,$subject,$multipart,$mailheaders); // отправляем письмо //удаляем файлы через 60 сек. if (time_nanosleep(5, 0)) < unlink($filepath); >// удаление файла Each line should be separated with a CRLF (\r\n). Lines should not be larger than 70 characters.
(Windows only) When PHP is talking to a SMTP server directly, if a full stop is found on the start of a line, it is removed. To counter-act this, replace these occurrences with a double dot.
String or array to be inserted at the end of the email header.
This is typically used to add extra headers (From, Cc, and Bcc). Multiple extra headers should be separated with a CRLF (\r\n). If outside data are used to compose this header, the data should be sanitized so that no unwanted headers could be injected.
If an array is passed, its keys are the header names and its values are the respective header values.
Note:
Before PHP 5.4.42 and 5.5.27, repectively, additional_headers did not have mail header injection protection. Therefore, users must make sure specified headers are safe and contains headers only. i.e. Never start mail body by putting multiple newlines.
Note:
When sending mail, the mail must contain a From header. This can be set with the additional_headers parameter, or a default can be set in php.ini .
Failing to do this will result in an error message similar to Warning: mail(): «sendmail_from» not set in php.ini or custom «From:» header missing . The From header sets also Return-Path when sending directly via SMTP (Windows only).
Note:
If messages are not received, try using a LF (\n) only. Some Unix mail transfer agents (most notably » qmail) replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with » RFC 2822.
The additional_params parameter can be used to pass additional flags as command line options to the program configured to be used when sending mail, as defined by the sendmail_path configuration setting. For example, this can be used to set the envelope sender address when using sendmail with the -f sendmail option.
This parameter is escaped by escapeshellcmd() internally to prevent command execution. escapeshellcmd() prevents command execution, but allows to add additional parameters. For security reasons, it is recommended for the user to sanitize this parameter to avoid adding unwanted parameters to the shell command.
Since escapeshellcmd() is applied automatically, some characters that are allowed as email addresses by internet RFCs cannot be used. mail() can not allow such characters, so in programs where the use of such characters is required, alternative means of sending emails (such as using a framework or a library) is recommended.
The user that the webserver runs as should be added as a trusted user to the sendmail configuration to prevent a ‘X-Warning’ header from being added to the message when the envelope sender (-f) is set using this method. For sendmail users, this file is /etc/mail/trusted-users .
Return Values
Returns true if the mail was successfully accepted for delivery, false otherwise.
It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.
Changelog
| Version | Description |
|---|---|
| 7.2.0 | The additional_headers parameter now also accepts an array . |
Examples
Example #1 Sending mail.
Using mail() to send a simple email:
// The message
$message = «Line 1\r\nLine 2\r\nLine 3» ;
// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap ( $message , 70 , «\r\n» );
// Send
mail ( ‘caffeinated@example.com’ , ‘My Subject’ , $message );
?>
Example #2 Sending mail with extra headers.
The addition of basic headers, telling the MUA the From and Reply-To addresses:
$to = ‘nobody@example.com’ ;
$subject = ‘the subject’ ;
$message = ‘hello’ ;
$headers = ‘From: webmaster@example.com’ . «\r\n» .
‘Reply-To: webmaster@example.com’ . «\r\n» .
‘X-Mailer: PHP/’ . phpversion ();
mail ( $to , $subject , $message , $headers );
?>
Example #3 Sending mail with extra headers as array
This example sends the same mail as the example immediately above, but passes the additional headers as array (available as of PHP 7.2.0).
$to = ‘nobody@example.com’ ;
$subject = ‘the subject’ ;
$message = ‘hello’ ;
$headers = array(
‘From’ => ‘webmaster@example.com’ ,
‘Reply-To’ => ‘webmaster@example.com’ ,
‘X-Mailer’ => ‘PHP/’ . phpversion ()
);
mail ( $to , $subject , $message , $headers );
?>
Example #4 Sending mail with an additional command line parameter.
The additional_params parameter can be used to pass an additional parameter to the program configured to use when sending mail using the sendmail_path .
Example #5 Sending HTML email
It is also possible to send HTML email with mail() .
// Multiple recipients
$to = ‘johny@example.com, sally@example.com’ ; // note the comma
// Subject
$subject = ‘Birthday Reminders for August’ ;
// Message
$message = ‘
Here are the birthdays upcoming in August!
| Person | Day | Month | Year |
|---|---|---|---|
| Johny | 10th | August | 1970 |
| Sally | 17th | August | 1973 |
‘ ;
// To send HTML mail, the Content-type header must be set
$headers [] = ‘MIME-Version: 1.0’ ;
$headers [] = ‘Content-type: text/html; charset=iso-8859-1’ ;
// Additional headers
$headers [] = ‘To: Mary , Kelly ‘ ;
$headers [] = ‘From: Birthday Reminder ‘ ;
$headers [] = ‘Cc: birthdayarchive@example.com’ ;
$headers [] = ‘Bcc: birthdaycheck@example.com’ ;
// Mail it
mail ( $to , $subject , $message , implode ( «\r\n» , $headers ));
?>
Note:
If intending to send HTML or otherwise Complex mails, it is recommended to use the PEAR package » PEAR::Mail_Mime.
Notes
Note:
The SMTP implementation (Windows only) of mail() differs in many ways from the sendmail implementation. First, it doesn’t use a local binary for composing messages but only operates on direct sockets which means a MTA is needed listening on a network socket (which can either on the localhost or a remote machine).
Second, the custom headers like From: , Cc: , Bcc: and Date: are not interpreted by the MTA in the first place, but are parsed by PHP.
As such, the to parameter should not be an address in the form of «Something «. The mail command may not parse this properly while talking with the MTA.
Note:
It is worth noting that the mail() function is not suitable for larger volumes of email in a loop. This function opens and closes an SMTP socket for each email, which is not very efficient.
For the sending of large amounts of email, see the » PEAR::Mail, and » PEAR::Mail_Queue packages.

PHP | Send Attachment With Email
Sending an email is a very common activity in a web browser. For example, sending an email when a new user joins a network, sending a newsletter, sending greeting mail, or sending an invoice. We can use the built-in mail() function to send an email programmatically. This function needs three required arguments that hold the information about the recipient, the subject of the message and the message body. Along with these three required arguments, there are two more arguments which are optional. One of them is the header and the other one is parameters.
We have already discussed sending text-based emails in PHP in our previous article. In this article, we will see how we can send an email with attachments using the Mime-Versionmail() function.
When the mail() function is called PHP will attempt to send the mail immediately to the recipient then it will return true upon successful delivery of the mail and false if an error occurs.
Syntax:
bool mail( $to, $subject, $message, $headers, $parameters );
Here is the description of each parameter.
| Name | Description | Required/Optional | Type |
|---|---|---|---|
| to | This contains the receiver or receivers of the particular email | Required | String |
| subject | This contains the subject of the email. This parameter cannot contain any newline characters | Required | String |
| message | This contains the message to be sent. Each line should be separated with an LF (\n). Lines should not exceed 70 characters (We will use wordwrap() function to achieve this.) | Required | String |
| headers | This contains additional headers, like From, Cc, Mime Version, and Bcc. | Optional | String |
| parameters | Specifies an additional parameter to the send mail program | Optional | String |
When we are sending mail through PHP, all content in the message will be treated as simple text only. If we put any HTML tag inside the message body, it will not be formatted as HTML syntax. HTML tag will be displayed as simple text.
To format any HTML tag according to HTML syntax, we can specify the MIME (Multipurpose Internet Mail Extension) version, content type and character set of the message body.
To send an attachment along with the email, we need to set the Content-type as mixed/multipart and we have to define the text and attachment sections within a Boundary.
Approach: Make sure you have a XAMPP server or WAMP server installed on your machine. In this article, we will be using the WAMP server.
Follow the steps given below:
Create an HTML form: Below is the HTML source code for the HTML form. In the HTML tag, we are using “enctype=’multipart/form-data” which is an encoding type that allows files to be sent through a POST method. Without this encoding, the files cannot be sent through the POST method. We must use this enctype if you want to allow users to upload a file through a form.
