php - 语法错误，意外 'Â Â Â Â ' (T_STRING)

Question

为什么我的 PHP 邮件代码总是给出:

syntax error, unexpected 'Â Â Â Â ' (T_STRING) in C:\xampp\htdocs\GSP\members.php on line 4

<?php
if(!isset($_POST['email'])) {
     
    $email_to = 'kennydharmawan@gmail.com'; //this is line 4
    $email_subject = "GSP Rent Order";
     
     
    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }
     
    // validation expected data exists
    if(!isset($_POST['name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['unit']) ||

为什么一直报这个错误？

Answer 1

您的问题是 PHP 文件保存了特殊的空白字符——即不是标准空格，而是一些其他字符呈现为空格(甚至根本不显示)，但 PHP 无法解析。

删除第 3 行和第 4 行的所有空白字符，重新键入它们并保存文件。 (这是所有的空白，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，您仍然收到错误，但在不同的行，那么您也需要对该行重复该过程。
