加载PHP页面，还可以在chrome浏览器中显示原始代码 - PHP pages load, but also show the raw code with them in chrome browser

我是PHP新手，我遇到了一点问题。

我的.php文件，我在Netbeans 7.3中编码，当我通过IDE的编译器运行它们时工作良好。但是当我在Google Chrome浏览器中运行这些网页时，同样的网页显示了原始代码和。

下面是一个示例代码-

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title> Add Your Highscore! </title>
    </head>
    <body>
        <h2> Guitar Wars - Add you highscore!</h2>
        <?php
        //echo "successful!!";

        if(isset($_POST['submit'])){
        $name=$_POST['name'];
        $score=$_POST['score'];
        $screenshot=$_FILES['screenshot']['name'];
        $screenshot_type=$_FILES['screenshot']['type'];
        $screenshot_size=$_FILES['screenshot']['size'];
        $output=false;
        if(!empty($name)&&!!empty($score)&&!empty($screenshot))
       {  
            if ((($screenshot_type == 'image/gif') || ($screenshot_type == 'image/jpeg') || ($screenshot_type == 'image/pjpeg') || ($screenshot_type == 'image/png'))
        && ($screenshot_size > 0) && ($screenshot_size <= GW_MAXFILESIZE)) {
        if ($_FILES['screenshot']['error'] == 0) {
          // Move the file to the target upload folder
          $target = 'images' . $screenshot;
          if (move_uploaded_file($_FILES['screenshot']['tmp_name'], $target)) 
            // Connect to the database
         {
            $db=  mysqli_connect('localhost','root', 'akash123','gwdb') 
                  or die('Error in connecting to the database');
        //echo "</br> successful connection";
        $query= "insert into guitar wars values(0,NOW(),$name, $score, $screenshot ";
        //echo "</br> successful query";
        $result= mysqli_query($db,$query) ;
       mysqli_close($db,$query);
       echo "</br> Successful!";
       $name='';
       $score='';
       $screenshot='';
        mysqli_close($db);
        }
        else
        {echo "There was a problem uploading the image";
        }
        }  
        else
        {echo "There was a problem uploading the image";
        $output=true;
        }
        }

        else{echo '<p class="error">The screen shot must be a GIF, JPEG, or PNG image file no greater than ' . (GW_MAXFILESIZE / 1024) . ' KB in size.</p>';
        $output=true;
        }}
        else{echo "* Enter all the information to add your highscore";
        $output=true;
        }
        }
        else
        { 
            $output=true;
            $name='';
            $score='';
        }
            if ($output){ 
            ?>
<form enctype="multipart/form-data" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <input type="hidden" name="MAX_FILE_SIZE" value="65536"/>
<label for="name">Full Name:</label>
<input type="text" id="name"  name="name" value="<?php echo $name ; ?>" /></br>
<label for="score">Your Highscore :</label>
<input type="text" id="score"  name="score" value="<?php echo $score ; ?>" /></br>
<label for="screenshot"> Screenshot of your Highscore: </label>
<input type="file" id="screenshot" name="screenshot" /></br>
<input type="submit" name="submit" value="Add"/>
</form>
    <?php
        }

        ?>
    </body>

Internet Explorer是绝望的，因为它试图下载。php文件。

这个结果的原因是什么?

你不能在浏览器中"打开" PHP文件，你必须"运行"它。Netbeans将运行文件(注意它们不会像Java那样编译)

如果您在本地机器上进行测试，则需要安装运行PHP的apache(例如xampp)。

如果您使用的是xampp:

打开xampp文件夹中的htdocs文件夹。

为你的webapp创建一个新文件夹

把你的PHP文件放到那个文件夹。

在你的浏览器中，导航到你的php页面(在地址栏中，输入运行xampp的机器的IP地址，或者localhost，或者你配置的其他地址，例如mylocalhostip/mywebapp/myphpfile.php)。

那么它应该可以正常工作

您的web服务器可能没有将文件传递给PHP解释器。检查你的web服务器配置
