PHP致命錯誤：函數名必須是錯誤

Question

一個字符串我有這樣的錯誤在我的錯誤日誌：

PHP Fatal error: Function name must be a string in /home2/x7w7i0o6/public_html/admin/mail.php on line 41 

這是從線41代碼：

if ($input->p['receiverlist'] == "single") { 
    $userid = getuserid($input->pc['username']); 

    if ($userid == 0) { 
     $serveranswer(0, "Username <strong>" . $input->pc['username'] . "</strong> was not found"); 
    } 

是什麼問題因爲郵件不工作。謝謝

不要把$放在函數名前面（除非你想要）。

$serveranswer(0, "Username <strong>" . $input->pc['username'] . "</strong> was not found"); 

應該是：

serveranswer(0, "Username <strong>" . $input->pc['username'] . "</strong> was not found");
