php - 我不知道为什么这段代码不断出现 t_string 错误

Question

我认为我做的一切都是正确的，但我在代码中不断收到 t_string 错误。我会显示什么行。如果有人能解决这个问题，我将非常感激。我确实对引号进行了研究，我认为数据库中的数据可能与错误有关，因为它包含 @ 符号和句点。

错误在第 76 行，即 if(empty($row['email']))

整个代码是

ini_set("include_path", ".:/public_html/phpmailer"); //Used for simplicity
include("mysql_connect.php"); //The database name, login, etc..
set_error_handler("customError"); //I created a custom error

$login = 'username@domain.com';
$password = 'password';
$server = '{imap.gmail.com:993/ssl/novalidate-cert}';
$connection = imap_open($server, $login, $password);

$mailboxinfo = imap_mailboxmsginfo($connection);
$messageCount = $mailboxinfo->Nmsgs; //Number of emails in the inbox
for ($MID = 1; $MID <= $messageCount; $MID++)
  {
  $EmailHeaders = imap_headerinfo($connection, $MID); //Save all of the header information
  $Body = imap_qprint(imap_fetchbody($connection, $MID, 1)); //The body of the email to be forwarded
  $MessageSentToAllArray = $EmailHeaders->to; //Grab the “TO” header
  $MessageSentToAllObject = $MessageSentToAllArray[0];
  $MessageSentToMailbox = $MessageSentToAllObject->mailbox; //Everything before the “@” of the recipient
  $MessageSentToHost = $MessageSentToAllObject->host; //Everything after the “@” of the recipient
  $MessageSentFromAllArray = $EmailHeaders->from; //Grab the “FROM” header
  $MessageSentFromAllObject = $MessageSentFromAllArray[0];
  $MessageSentFromMailbox = $MessageSentFromAllObject->mailbox; //Everything before the “@” of the sender
  $MessageSentFromHost = $MessageSentFromAllObject->host; //Everything after the “@” of the sender
  $MessageSentFromName = $MessageSentFromAllObject->personal; //The name of the person who sent the email
  $toArray = searchRecipient($MessageSentToMailbox); //Find the correct person to send the email to
  if($toArray == FALSE) //If the alias they entered doesn’t exist…

    $mail->SetFrom($from_email_address, "Domain.Com");
    $address = "$MessageSentFromMailbox@$MessageSentFromHost"; //Who we’re sending the email to
    $mail->AddAddress($address, $MessageSentFromName);
    $mail->Subject = 'WAHM Link Request'; //Subject of the email
    $mail->Body = $the_body;
    if(!$mail->Send()) //If the mail fails, send to customError
      {
      customError(1, $mail->ErrorInfo, "anon-email.php", "sending the email");
      }
    }
  else //If the candidate address exists, forward on the email
    {
    $mail = new PHPMailer(); // defaults to using php “mail()”
    $mail -> ContentType = ‘text/plain’; //Plain E-mail
    $mail -> IsHTML(FALSE); //No HTML
    $the_body = wordwrap($Body, 70); //Wordwrap for proper email formatting
    $from_email_address = "$MessageSentFromMailbox@$MessageSentFromHost";
    $mail->AddReplyTo($from_email_address, $MessageSentFromName);
    $mail->SetFrom($from_email_address, $MessageSentFromName);

  /* Mark the email for deletion after processing */

我花了很长时间才弄清楚这个问题，尤其是因为 stackoverflow 似乎已经为您解决了这个问题。在空白 block 中间有许多 0xA0 字符随机散布在您的源代码中(我的编辑器计数为 33)。 PHP 解析器显然不太喜欢这些并抛出错误。

我刚刚在我的编辑器中执行了查找/替换操作，将它们全部转换为空格 (0x20)，现在可以解析了。

似乎我第一次编辑你的问题时把它给大家破坏了，因为 SO 纠正了问题，我现在不能通过复制当前显示的代码来重复它，尽管回滚到原始版本- 对不起大家。

如果您将上述代码复制并粘贴回您的编辑器，问题就会消失。 StackOverflow 已积极解决该问题。
