Question

当我尝试从localhost（localhost / PrimaAppAndroid / register.php）打开文件register.php时，页面仍为白色，如果我尝试查看源文件，则为空。如果我从register.php离开php部分，即使我没有在html中更改扩展名php也能正常工作。

我看到了similar question，我在AddType application/x-httpd-php .php文件的末尾添加了apache2.conf，但没有任何变化。怎么解决这个问题？

这里的消息来源： register.php

<?php 
/*
Our "config.inc.php" file connects to database every time we include or require
it within a php script.  Since we want this script to add a new user to our db,
we will be talking with our database, and therefore,
let's require the connection to happen:
*/
    require("config.inc.php");
?>

<h1>Register</h1> 
<form action="register.php" method="post"> 
    Username:<br /> 
    <input type="text" name="username" value="" /> 
    <br /><br /> 
    Password:<br /> 
    <input type="password" name="password" value="" /> 
    <br /><br /> 
    <input type="submit" value="Register New User" /> 
</form>

的config.inc.php：

<?php 

    // These variables define the connection information for your MySQL database 
    $username = "root"
    $password = "root"
    $host = "localhost"
    $dbname = "cinemapreverificasql"

    // Tis is the way we saw in class
    $conn = mysql_connect($host, $username, $password) or die("Errore nella connessione MySQL");
    mysql_select_db($dbname, $conn) or ide("Database inesistente");
?>

Answer 1

config.inc.php变量中没有分号？

Answer 2

错误的另一个可能来源：

mysql_select_db($dbname, $conn) or ide("Database inesistente");

应该是

mysql_select_db($dbname, $conn) or die("Database inesistente");

Answer 3

Ciao Giacomotb，如果您正确发布代码，则config.inc.php文件中会出现拼写错误。

mysql_select_db($dbname, $conn) or ide("Database inesistente");

正如您在最后看到的那样，您使用了die函数，但是您编写了ide，只需修复它就可以了

另外你忘记了php变量末尾的分号。

$username = "root"
    $password = "root"
    $host = "localhost"
    $dbname = "cinemapreverificasql"

必须是

$username = "root";
    $password = "root";
    $host = "localhost";
    $dbname = "cinemapreverificasql";

Answer 4

我注意到你的代码有错误，因为（;）在你宣布的varaiables结束时遗漏了。

<?php 

    // These variables define the connection information for your MySQL database 
    $username = "root";
    $password = "root";
    $host = "localhost";
    $dbname = "cinemapreverificasql";

    // Tis is the way we saw in class
    $conn = mysql_connect($host, $username, $password) or die("Errore nella connessione MySQL");
    mysql_select_db($dbname, $conn) or ide("Database inesistente");
?>

另一件事是尝试将您的文件重命名为config.inc.php并将名称重新命名为config_inc.php

无法打开php文件，源文件似乎是空的
