为什么总是不停地说这个错误？

Answer 1

你的问题是PHP文件已经保存了异国情调的空白字符 - 也就是说不是标准空格，而是一些其他字符被渲染为空格（甚至根本不显示），但是PHP不能解析。

删除第3行和第4行的所有空白字符，重新输入并保存文件。 （即全部为空格，包括换行符和单词之间的空格）

这应该可以解决问题。

如果执行此操作后仍然出现错误，但在另一行上，则需要重复该行的过程。

我看到你的代码中的一些错误：

尝试更换：

$email_to = 'kennydharmawan@gmail.com'; 

有了：

$email_to = "kennydharmawan@gmail.com"; 

而在这行：

echo "Thank you for contacting us. We will be in touch with you very soon." 

你失踪一个“;”，所以修复它：

echo "Thank you for contacting us. We will be in touch with you very soon."; 

PS：尝试用双引号（ '' 与 “”）替换所有单引号我所有字符串瓦尔）
