您好我有一个简单的数据库连接测试php文件(index.php)应该用include语句调用另一个页面(output.html.php),但它似乎不起作用。请帮忙。以下是两个文件的代码。谢谢。

index.php

<?php
try
{
        $pdo =  new PDO('mysql:host=localhost;dbname=ijdb', 'ijdbuser', 'mypassword');
        $pdo->setAttribute(PDO::ALTER_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $PDO->exec('SET NAMES "utf8");
}
catch (PDOException $e)
{
        $output = 'Unable to connect to the database server.';
        include = 'output.html.php';
        exit();
}

$output = 'Database connection established.';
include 'output.html.php';
?>

output.html.php

<!DOCTYPE html>
<html lang="en-us">
        <meta charset="UTF-8" >
        <title>DB Example</title>
        <head>
        </head>

        <body>

                <p>
                <?php echo $output; ?>
                </p>

        </body
</html>

我只是得到空白页。

    index.php:

    <?php
    try
    {

            $pdo =  new PDO('mysql:host=localhost;dbname=ijdb', 'ijdbuser', 'mypassword');
            $pdo->setAttribute(PDO::ALTER_ERRMODE, PDO::ERRMODE_EXCEPTION);
            $dbh->exec("SET CHARACTER SET utf8");//$PDO->exec('SET NAMES "utf8");

            header("location:output.html.php?msg=Database%20connection%20established");
    }
    catch (PDOException $e)
    {
                            header("location:output.html.php?msg=Unable%20to%20connect%20to%20the%20database%20server");

    }

?>

我理解如果你包含文件它重定向到那个空白的页面,因此没有按钮($输出)显示。如果你应用重定向方法,你移动到失败和成功所需的消息显示。

output.html.php: -

<!DOCTYPE html>
<html lang="en-us">
        <meta charset="UTF-8" >
        <title>DB Example</title>
        <head>
        </head>

        <body>

                <p>
                <?php if(isset($_GET['msg'])){echo $_GET['msg'];} ?>
                </p>

        </body
</html>

可能你在问题中错过了字符串的结尾并且已经解决了它。无论如何,这里有一点错误:index.php,首先尝试{}阻止:

...
$PDO->exec('SET NAMES "utf8");
... 

应该是:

$PDO->exec('SET NAMES "utf8"');

希望它对你有所帮助。正如您在答案和评论中看到的那样,在PHP开发环境中启用错误是解决此问题的最佳方法&#34;白屏死机&#34;错误。以下是关于最后一个主题的参考:http://www.php.net/manual/en/errorfunc.configuration.php#89648
