我正在使用Laravel 5.每当我输入
php artisan tinker
我得到预期的输出前面有一个字母c：
cPsy Shell v0.5.2 (PHP 5.6.10-1+deb.sury.org~trusty+1 — cli) by Justin Hileman
当我输入php artisan
我得到的第一行是：
cLaravel Framework version 5.1.16 (LTS)
不知何故，这封信显示在我的所有观点上，所以搞乱了我的项目。当我点击“查看页面来源”时，我在“<!DOCTYPE html>”之前看到字母“c”，但我无法在任何文件中找到它。

尝试这个技巧：
输入您选择的控制器方法此代码：
django.contrib.admin.util如果一切顺利，PHP将无法发送标头，并在错误消息中写入文件和输出（“c”）开始的行。
注意：如果您正在使用输出缓冲，则无法使用此功能。

您可能会在任何始终包含的源文件的开头意外输入“c”（如果不是artisan本身：
c<?php
现在，您可以使用原始未修改的文件替换Laravel源，也可以搜索上面的字符串，例如：
rgrep "c<?php" .
在相关说明中：使用像Git这样的版本控制系统，您将不会遇到这些问题。

我建议打开<?php

并检查是否存在某种index.php或echo "c";。根据你的问题和评论，你的所有观点都有这样的字母似乎是索引文件或主要布局文件是问题所在。 （我倾向于print "c";文件，因为您在doctype之前看到了这封信。）
