我发送附件邮件时出错警告：filesize（）

Question

Error:

Warning: filesize() [function.filesize]: stat failed for http://website.com/wp-content/uploads/2015/06/ddlg.jpg in /home4/moses/public_html/website.com/ipn-page-template .php on line 72

My Code:

$path = 'http://website.com/wp-content/uploads/2015/06/';
    $filename = 'unnamed.jpg';
    $mailto = 'email@domain.com';
    $subject = "Thank you for Than Near";

    $file = $path . $filename;
    $file_size = filesize($file);

Answer 1

Filesize can allow checking the size of remote items via fopen wrappers if given a URL (as you're doing), but like many such things it's not reliable. Make sure fopen wrappers are enabled, and that you can reach the item first before trying to use it.

If you're doing this during a page load, you're also asking for it to hang if the remote host does not respond, so you should really pre-fetch images and serve them from a local file store.

Writing your own email code is never a good idea; Use a library .
