PHP's mail() function
PHP easy E-Mail
The easiest way to send an email through PHP is to send a text email.
<?php $to = "someone@example.com"; // Mail recipient $subject = "Parameter mail"; // Mail title $message = "Hello! This is the content of the message."; // Mail text $from = "someonelse@example.com"; // Email Sender $headers = "From:" . $from; // Header information settings mail($to,$subject,$message,$headers); echo "Message sent"; ?>
PHP Mail form
With PHP, you can create a feedback form on your own site. The following example sends a text message to the specified e-mail address:
<html>
<head>
<meta charset="utf-8">
<title>Rookie tutorial(runoob.com)</title>
</head>
<body>
<?php
if (isset($_REQUEST['email'])) { // Send mail if mailbox parameters are received
// Send mail
$email = $_REQUEST['email'] ;
$subject = $_REQUEST['subject'] ;
$message = $_REQUEST['message'] ;
mail("someone@example.com", $subject,
$message, "From:" . $email);
echo "Mail sent successfully";
} else { // Show form if there is no mailbox parameter
echo "<form method='post' action='mailform.php'>
Email: <input name='email' type='text'><br>
Subject: <input name='subject' type='text'><br>
Message:<br>
<textarea name='message' rows='15' cols='40'>
</textarea><br>
<input type='submit'>
</form>";
}
?>
</body>
</html>
PHP prevents E-mail injection
The best way to prevent e-mail injection is to validate the input. Add the input verifier to detect the email field in the form:
<html>
<head>
<meta charset="utf-8">
<title>Rookie tutorial(runoob.com)</title>
</head>
<body>
<?php
function spamcheck($field)
{
// Filter? Var() to filter e-mail
// Use filter? Sanitize? Email
$field=filter_var($field, FILTER_SANITIZE_EMAIL);
//Filter? Var() to filter e-mail
// Use filter? Validate? Email
if(filter_var($field, FILTER_VALIDATE_EMAIL))
{
return TRUE;
}
else
{
return FALSE;
}
}
if (isset($_REQUEST['email']))
{
//Send mail if mailbox parameters are received
// Judge whether the mailbox is legal
$mailcheck = spamcheck($_REQUEST['email']);
if ($mailcheck==FALSE)
{
echo "illegal input";
}
else
{
// Send mail
$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
{
// Show form if there is no mailbox parameter
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>
