是什么导致意外的T_CONSTANT_ENCAPSED_STRING错误? [英] What causes unexpected T_CONSTANT_ENCAPSED_STRING error?

问题描述

我有一个简单的PHP脚本，不断抛出此奇怪的错误消息:

I have a simple PHP script that keeps throwing this bizarre error message:

解析错误:语法错误，/script.php中出现意外的'"string"(T_CONSTANT_ENCAPSED_STRING)

Parse error: syntax error, unexpected '"string' (T_CONSTANT_ENCAPSED_STRING) in /script.php

 <?php
    error_reporting(-1);
    require_once "PHPMailer/PHPMailerAutoload.php";

    $api_key = "string"; // this line causes the error
    $payload = file_get_contents("php://input");

    $new_booking = json_decode($payload, true);
    $schedule_id = "123456";
    $schedule_link = "http://example.com";
    $passwd = "passwd";

    // email config
    $admin = [
        "name" => "Joe White", 
        "user" => "[e-mail]", 
        "passwd" => "passwd"
    ];

    $max_time = 3; // hours
    $max_dist = 200; // miles

    /*
    Code goes on, but is commented out and therefore not included here
    */
    ?>

我看到有人在另一个SO问题中提到问题可能是CRLF行尾而不是CF，但是我不确定.

I saw somebody mention in another SO question that the issue might be CRLF line endings instead of CF, but I'm not sure.

推荐答案

好吧，我最终自己找到了解决方案，该错误是由于某些损坏的空格/换行符引起的，并且由于我不想遍历整个文件，我使用了那些工具:

Well, I ended up finding a solution myself, the error was due to some corrupt whitespace/linefeed characters, and since I didn't want to go through the entire file, I used those tools:

这可以验证代码: http://phpcodechecker.com

这可以再次美化代码: http://www.cleancss.com/php-beautify/

And this to beautify the code again: http://www.cleancss.com/php-beautify/

确保在此过程之前删除所有单行注释.
