在PHP中发送带附件的电子邮件,而不将文件保存到Web服务器,可以使用PHP的内置函数mail()
和PHPMailer
库。以下是使用mail()
函数发送带附件的电子邮件的示例代码:
<?php
$to = "recipient@example.com";
$subject = "Test email with attachment";
$message = "This is a test email with attachment.";
$headers = "From: sender@example.com";
// Define the attachment
$file_name = "example.pdf";
$file_path = "/path/to/example.pdf";
$file_type = "application/pdf";
$file_contents = file_get_contents($file_path);
$attachment = chunk_split(base64_encode($file_contents));
// Set the headers for the attachment
$headers .= "\nMIME-Version: 1.0";
$headers .= "\nContent-Type: multipart/mixed; boundary=\"boundary\"";
$headers .= "\nContent-Disposition: inline";
$headers .= "\n--boundary";
$headers .= "\nContent-Type: text/plain; charset=ISO-8859-1";
$headers .= "\nContent-Transfer-Encoding: 7bit";
$headers .= "\n\n" . $message;
$headers .= "\n\n--boundary";
$headers .= "\nContent-Type: " . $file_type . "; name=\"" . $file_name . "\"";
$headers .= "\nContent-Disposition: attachment; filename=\"" . $file_name . "\"";
$headers .= "\nContent-Transfer-Encoding: base64";
$headers .= "\nX-Attachment-Id: " . rand(1000, 99999);
$headers .= "\n\n" . $attachment;
$headers .= "\n--boundary--";
// Send the email
if (mail($to, $subject, "", $headers)) {
echo "Email sent successfully!";
} else {
echo "Error sending email.";
}
?>
在这个示例中,我们首先定义了收件人、主题、正文和发件人头信息。然后,我们定义了要附加的文件,并将其内容转换为Base64编码。接下来,我们设置了附件的头信息,并将其添加到现有的头信息中。最后,我们使用mail()
函数发送电子邮件。
另一种方法是使用PHPMailer
库,它提供了更多的功能和更好的错误处理。以下是使用PHPMailer
库发送带附件的电子邮件的示例代码:
<?php
require 'PHPMailer/PHPMailer.php';
require 'PHPMailer/SMTP.php';
require 'PHPMailer/Exception.php';
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;
$mail = new PHPMailer(true);
try {
// Server settings
$mail->SMTPDebug = SMTP::DEBUG_SERVER;
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'username';
$mail->Password = 'password';
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = 587;
// Recipients
$mail->setFrom('sender@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
// Attachment
$mail->addAttachment('/path/to/example.pdf', 'example.pdf');
// Content
$mail->isHTML(true);
$mail->Subject = 'Test email with attachment';
$mail->Body = 'This is a test email with attachment.';
// Send the email
$mail->send();
echo 'Email sent successfully!';
} catch (Exception $e) {
echo "Error sending email: {$mail->ErrorInfo}";
}
?>
在这个示例中,我们首先引入了PHPMailer
库,并创建了一个新的PHPMailer
对象。然后,我们设置了SMTP服务器的设置,收件人,发件人,附件和电子邮件内容。最后,我们使用send()
方法发送电子邮件。
总之,使用mail()
函数或PHPMailer
库,您可以在PHP中发送带附件的电子邮件,而不需要将文件保存到Web服务器。
