Unexpected equal sign in php when creating PDO object

本文关键字：意外对象 PDO php 创建 | 更新日期: 2023-09-27

config.php

<?php
    try{
        connection = new PDO("mysql:dbname=9lessons;host=localhsot", "root", "");
    }catch(PDOException $error){
        echo $error->getMessage();
    }
?>

main.php

<?php
    include ('config.php');
    foreach ($connection->query('SELECT * FROM message LIMIT 9') as $row)
    {
        $msg = $row['msg'];
        $mes_id=$row['mes_id'];
        $up=$row['up'];
        $down=$row['down'];
 ?>
<div class="main">
<div class="box1">
<div class="up">
<a href=""class="vote" id="<?php echo $mes_id?>" name="up">
<?php echo $up; ?></a></div>
<div class="down">
<a href="" class="vote" id="<?php echo $mes_id; ?>" name="down">
<?php echo $down; ?></a></div>
</div>
<div class="box2"><?php echo $msg; ?></div>
</div>
<?php } ?>

当我运行上面的代码时，我得到了如下错误消息：

Parse error: syntax error, unexpected '=' in C:'xampp'htdocs'config.php on line 3

变量以$:开头

$connection = new PDO("mysql:dbname=9lessons;host=localhsot", "root", "");

任何时候你有一个Parse error: syntax error, unexpected-找到意想不到的东西，慢慢地回溯寻找语法错误。
