如何阅读和发送资源？

我需要生成并发送日志数据到csv格式的邮件。这里是我的代码：如何阅读和发送资源？

public function sendMail(){ 
    $csv = $this->createCSV(); 
    $subject = $this->getMessage('subject'); 
    $message = $this->getMessage('message'); 
    $headers = $this->generateHeaders($csv, $message); 

    mail('[email protected]', $subject, $message, $headers); 
} 

private function createCSV(){ 
    $data = $this->getAVG(); 

    $csv = fopen('php://temp', 'w+'); 

    // long statistics generation 

    fclose($csv); 

    return $csv; 
} 

private function generateHeaders($file, $message){ 
    $boundary = md5(uniqid(time())); 

    $headers = 'MIME-Version: 1.0'."\r\n"; 
    $headers .= 'Content-Type: multipart/mixed; boundary="'.$boundary."\"\r\n"; 
    $headers .= 'From: [email protected]'.$_SERVER['SERVER_NAME']."\r\n"; 

    $headers .= '--'.$boundary."\r\n"; 

    $headers .= "Content-Type: text/html; charset=utf-8\r\n"; 
    $headers .= "Content-Transfer-Encoding: base64\r\n"; 
    $headers .= "\r\n"; 
    $headers .= chunk_split(base64_encode($message)); 

    $headers .= '--'.$boundary."\r\n"; 

    $headers .= "Content-Type: text/csv; name=\"ServersLogs.csv\"\r\n"; 
    $headers .= "Content-Transfer-Encoding: base64\r\n"; 
    $headers .= "Content-Disposition: attachment; filename=\"ServersLogs.csv\"\r\n"; 
    $headers .= "\r\n"; 
    $headers .= chunk_split(base64_encode(readfile($file))); 

    $headers .= "\r\n--".$boundary."--\r\n"; 

    return $headers; 
}

的问题是，我不能保存文件的服务器上，所以我用php://，之后却无法读取文件...

你有没有试过将文件保存在'/ tmp'上？你应该有权限在那里。 – fedorqui 2013-02-20 09:49:26
