email - 将电子邮件传送到解析器脚本时获取 "Error in argument 1, char 3: option not found"

Question

当我尝试发送符合条件的电子邮件以将电子邮件传输到我的 PHP 脚本时，出现错误。错误是:

pipe to |/home/**********/**********/script.php
  generated by f1c8f287-02ea81a3-11a218b30839@**********.com

The following text was generated during the delivery attempt:

我不想让这个问题不必要地冗长......

为了以防万一，这是我完整的 script.php 代码:

#!/usr/bin/php -q
<?php

// config
$dbHost = "********";
$dbUser = "********";
$dbPass = "********";
$dbName = "********";

//$conn = mysqli_connect($dbHost, $dbUser, $dbPass, $dbName) or die(mysqli_error($conn));
$notify= 'admin@*********.com'; // an email address required in case of errors

function mailRead($iKlimit = "") 
    { 
        // Purpose: 
        //   Reads piped mail from STDIN 
        // 
        // Arguments: 
        //   $iKlimit (integer, optional): specifies after how many kilobytes reading of mail should stop 
        //   Defaults to 1024k if no value is specified 
        //     A value of -1 will cause reading to continue until the entire message has been read 
        // 
        // Return value: 
        //   A string containing the entire email, headers, body and all. 
         
        // Variable perparation         
            // Set default limit of 1024k if no limit has been specified

        }

            while (!feof($fp)) { 
                $sEmail .= fread($fp, 1024); 
            }                     
        } else { 
            while (!feof($fp) && $i_limit < $iKlimit) { 
                $sEmail .= fread($fp, 1024); 
                $i_limit++; 
            }         
        } 
         
        // Close connection to STDIN 
        fclose($fp);

$from = "";
$subject = "";
$headers = "";
$message = "";
$splittingheaders = true;

for ($i=0; $i < count($lines); $i++) {
    if ($splittingheaders) {
        // this is a header
        $headers .= $lines[$i]."\n";

        // look out for special headers
        if (preg_match("/^Subject: (.*)/", $lines[$i], $matches)) {
            $subject = $matches[1];
        }

        if (preg_match("/^To: (.*)/", $lines[$i], $matches)) {
            $to = $matches[1];
        }
    } else {
        // not a header, but message
        $message .= $lines[$i]."\n";
    }

        $splittingheaders = false;

if ($conn = mysqli_connect($dbHost,$dbUser,$dbPass)) {

  if (mysqli_affected_rows() == 0)
    mail($notify,'Email Logger Error',"There was an error inserting into the email logger database.\n\n".mysqli_error());
} else {
  mail($notify,'Email Logger Error',"There was an error connecting the email logger database.\n\n".mysqli_error());
}
?>

我遵守了这些规则并且它们在检查中:

1. 文件权限(及其目录)设置为 0755

2. 通过 cPanel 上传。该文件应该是 ascii 格式而不是二进制格式(我不知道如何检查)

3. 在 php 标签和 hashbang 之前/之后没有空格/换行符

我查看并尝试了这些问题的答案，这些问题很相似，但没有解决我遇到的错误:

此问题的解决方案是确保为 Unix 保存脚本的行尾。如果您使用的是 Windows，请检查文本编辑器用于保存行尾的默认设置。相关问题证明在处理这个问题时很有用，How do configure sublime to always convert to unix line endings on save?

对于 Sublime Text 3，我只是更改了行尾格式(菜单 > View > 行尾 > Unix)并保存了文件。电子邮件解析器现在可以正常工作。

这个出色的解决方案归功于 Triplee。对于 future 的读者，如果您是 Windows 用户，一般故障排除论坛会提到无关的回车符，但不会提及将文本格式化为 Unix 行结尾的任何内容。
