PHP E-mail Function
The PHP mail() function allows you to send e-mails directly from a script.
Syntax
mail(to,subject,message,headers,parameters)
Parameter Description
to : Required. Specifies the receiver / receivers of the email.
subject : Required. Specifies the subject of the email. Note: This parameter cannot contain any newline characters.
message : Required. Defines 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, like From, Cc, and Bcc. The additional headers should be separated with a CRLF (\r\n).
parameters : Optional. Specifies an additional parameter to the sendmail program.
Note: For the mail functions to be available, PHP requires an installed and working email system. The program to be used is defined by the configuration settings in the php.ini file.
PHP Simple E-Mail
The simplest way to send an email with PHP is to send a text email.
In the example below we first declare the variables ($to, $subject, $message, $from, $headers), then we use the variables in the mail() function to send an e-mail:
<?php
$to = "someone@example.com";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "billgates@example.com";
$headers = "From: $from";
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?>
PHP Mail Form
With PHP, you can create a feedback-form on your website. The example below sends a text message to a specified e-mail address:
<html>
<body>
<?php
if (isset($_REQUEST['email']))
//if "email" is filled out, send email
{
//send email
$email = $_REQUEST['email'] ;
$subject = $_REQUEST['subject'] ;
$message = $_REQUEST['message'] ;
mail( "someone@example.com", "Subject: $subject",
$message, "From: $email" );
echo "Thank you for using our mail form";
}
else
//if "email" is not filled out, display the form
{
echo "<form method='post' action='mailform.php'>
Email: <input name='email' type='text' /><br />
Subject: <input name='subject' type='text' /><br />
Message:<br />
<textarea name='message' rows='15' cols='40'>
</textarea><br />
<input type='submit' />
</form>";
}
?>
</body>
</html>
This is how the example above works:
First, check if the email input field is filled out.
If it is not set (like when the page is first visited); output the HTML form.
If it is set (after the form is filled out); send the email from the form
When submit is pressed after the form is filled out, the page reloads, sees that the email input is set, and sends the email.
