警告: filesize() [< C:\wamp\www\Graph\php\php.txt的href='function.filesize'>function.filesize</a>]：统计失败

Question

我正在编写一个代码，用于发送带有附件的邮件。但是我得到了这个关于文件大小的错误，并且还得到了以下错误：

Warning: fopen(C:\wamp\www\Graph\php\php.txt) [<a href='function.fopen'>function.fopen</a>]: failed to open stream:

Warning: fread() expects parameter 1 to be resource,

Warning: fclose() expects parameter 1 to be resource

我是初学者，请试着解决我的问题。下面是我的代码：

<?php
       mail_attachment('php.txt', 'C:\\wamp\\www\\Graph\\php\\', 'saurabh.d.sharma@ericsson.com',
                           'saurabh.d.sharma@ericsson.com', 'Saurabh Sharma D', 'saurabh.d.sharma@ericsson.com',
                           'Hello Mail Send With PHP', 'Please find the attached');
                          // mail_attachment($filename, $path, $mailto, $from_mail, $from_name, $replyto, $subject, $message);
function mail_attachment($filename, $path, $mailto, $from_mail, $from_name, $replyto, $subject, $message) {
    ini_set('sendmail_from', 'saurabh.d.sharma@ericsson.com');
    ini_set( 'SMTP', "smtp.internal.ericsson.com" );
    $file = $path.$filename;
    $file_size = filesize($file);
    $handle = fopen($file, "r");
    $content = fread($handle, $file_size);
    fclose($handle);
    $content = chunk_split(base64_encode($content));
    $uid = md5(uniqid(time()));
    $name = basename($file);
    $header = "From: ".$from_name." <".$from_mail.">\r\n";
    $header .= "Reply-To: ".$replyto."\r\n";
    $header .= "MIME-Version: 1.0\r\n";
    $header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
    $header .= "This is a multi-part message in MIME format.\r\n";
    $header .= "--".$uid."\r\n";
    $header .= "Content-type:text/plain; charset=iso-8859-1\r\n";
    $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
    $header .= $message."\r\n\r\n";
    $header .= "--".$uid."\r\n";
    $header .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"; // use different content types here
    $header .= "Content-Transfer-Encoding: base64\r\n";
    $header .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n";
    $header .= $content."\r\n\r\n";
    $header .= "--".$uid."--";
    if (mail($mailto, $subject, "", $header)) {
        echo "mail send ... OK"; // or use booleans here
    } else {
        echo "mail send ... ERROR!";
    }
}
?>

Answer 1

您的脚本无法找到(或读取)文件C:\wamp\www\Graph\php\php.txt

Answer 2

您应该检查指定的文件是否可以打开：

$file = $path.$filename;
if ($handle = fopen($file, "r")) {
  $file_size = filesize($file);
  $content = fread($handle, $file_size);
  fclose($handle);
}
else {
  die("Error reading file: " . $file);
}
