How can PHP beginners effectively troubleshoot issues with sending emails with attachments?

To troubleshoot issues with sending emails with attachments in PHP, beginners can check if the file path to the attachment is correct, verify that the attachment is not too large, and ensure that the email server settings are correct. Additionally, using PHP's built-in mail() function along with the MIME type for attachments can help resolve any problems. 

$to = 'recipient@example.com';
$subject = 'Test Email with Attachment';
$message = 'This is a test email with attachment.';
$attachment = 'path/to/attachment.pdf';

$filename = basename($attachment);
$file_content = file_get_contents($attachment);
$attachment_content = chunk_split(base64_encode($file_content));

$boundary = md5(time());
$headers = "From: sender@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: multipart/mixed; boundary=\"{$boundary}\"\r\n";

$body = "--{$boundary}\r\n";
$body .= "Content-Type: text/plain; charset=\"UTF-8\"\r\n";
$body .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$body .= $message . "\r\n";

$body .= "--{$boundary}\r\n";
$body .= "Content-Type: application/pdf; name=\"{$filename}\"\r\n";
$body .= "Content-Transfer-Encoding: base64\r\n";
$body .= "Content-Disposition: attachment; filename=\"{$filename}\"\r\n\r\n";
$body .= $attachment_content . "\r\n";

$body .= "--{$boundary}--";

mail($to, $subject, $body, $headers);
