PHP 5 mail() Function

PHP allows you to send e-mails directly from a script.

The PHP mail() Function

It is common to send input data from a web form to an email address (typically to the webmaster's email address).

PHP provides a convenient way to send email with the mail() function.



Parameter Description
to Required. Specifies the recipient's email address(es)
subject Required. Specifies the email's subject line. Note: This parameter cannot contain any newline characters
message Required. Specifies the actual email body (the message to be sent). Each line should be separated with a LF (\n). Lines should not exceed 70 characters
headers Optional. Specifies additional headers such as "From", "Cc", "Bcc", etc. The additional headers should be separated with a CRLF (\r\n)
parameters Optional. Specifies any additional parameters

PHP Send Mail Example (NON-SECURE!)

Assume we have the following PHP code on a page:

<h2>Feedback Form</h2>
// display form if user has not clicked submit
if (!isset($_POST["submit"])) {
  <form method="post" action="<?php echo $_SERVER["PHP_SELF"];?>">
  From: <input type="text" name="from"><br>
  Subject: <input type="text" name="subject"><br>
  Message: <textarea rows="10" cols="40" name="message"></textarea><br>
  <input type="submit" name="submit" value="Submit Feedback">
} else {    // the user has submitted the form
  // Check if the "from" input field is filled out
  if (isset($_POST["from"])) {
    $from = $_POST["from"]; // sender
    $subject = $_POST["subject"];
    $message = $_POST["message"];
    // message lines should not exceed 70 characters (PHP rule), so wrap it
    $message = wordwrap($message, 70);
    // send mail
    mail("",$subject,$message,"From: $from\n");
    echo "Thank you for sending us feedback";

Example explained:

  • If the form has not been submitted; display the HTML feedback form
  • When the user clicks on the submit button, check if the "from" input field is filled out
  • Get the input data from form
  • Send mail with PHP mail() function
