【解決方法】PHP の行末エラー

こんにちはチーム

私は中括弧の終わりをどこで省略できるかを見つけようとしています。私ははっきりと見えないようで、私のIDEを使用しています。 この問題の解決にご協力ください

私が試したこと：

<?php
function multi_attach_mail($to, $subject, $message, $senderEmail, $senderName, $received_email_send = array()){
  
  // Sender info
$from = $senderName. '<.$senderEmail.>';
$headers = 'From: $from';

// Boundary
$semi_rand = md5(time());
$mime_boundary = '==Multipart_Boundary_x{$semi_rand}x';

// Headers for attachment
$headers .= '\nMIME-Version: 1.0\n' .
"Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\"";

// Multipart boundary
$message = "–{$mime_boundary}\n" . "Content-Type: text/html; charset=\"UTF-8\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n";

// Preparing attachment
if(!empty($received_email_send)){
for($i=0;$i<count($received_email_send);$i++){
if(is_file($received_email_send[$i])){
$file_name = basename($received_email_send[$i]);
$file_size = filesize($received_email_send[$i]);
}
}
}
$message .= "–{$mime_boundary}\n";
$fp = @fopen($received_email_send[$i], "rb");
$data = @fread($fp, $file_size);
@fclose($fp);
$data = chunk_split(base64_encode($data));
"Content-Disposition: attachment; filename=\"".$file_name."\"\n" .
"Content-Length: ".$file_size."\n" .
"Content-Type: application/octet-stream; name=\"".$file_name."\"\n" .
"Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
}
}
}

$message .= "–{$mime_boundary}\n";
$returnpath = "-f" . $senderEmail;

// Send email
$mail = mail($to, $subject, $message, $headers, $returnpath);
// Return true if email sent, otherwise return false
if($mail){
return true;
}else{
return false;

}
?>
