php代码显示，而不是运行

问题描述：

我使用php 5.2.4与wampserver。一切都很顺利。几天后我做了几件作品。没有问题。php代码显示，而不是运行

但是我面临着一个奇怪的问题。我为页面编写的脚本显示而不是渲染的网页。我的页面在这里给出：

<?php 
if(isset($_POST['email'])) { 

    // EDIT THE 2 LINES BELOW AS REQUIRED 
    $email_to = "[email protected]"; 
    $email_subject = "Your email subject line"; 


    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($_POST['first_name']) || 
     !isset($_POST['last_name']) || 
     !isset($_POST['email']) || 
     !isset($_POST['telephone']) || 
     !isset($_POST['comments'])) { 
     died('We are sorry, but there appears to be a problem with the form you submitted.');  
    } 

    $first_name = $_POST['first_name']; // required 
    $last_name = $_POST['last_name']; // required 
    $email_from = $_POST['email']; // required 
    $telephone = $_POST['telephone']; // not required 
    $comments = $_POST['comments']; // required 

    $error_message = ""; 
    $email_exp = '/^[A-Za-z0-9._%-][email protected][A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/'; 
    if(!preg_match($email_exp,$email_from)) { 
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />'; 
    } 
    $string_exp = "/^[A-Za-z .'-]+$/"; 
    if(!preg_match($string_exp,$first_name)) { 
    $error_message .= 'The First Name you entered does not appear to be valid.<br />'; 
    } 
    if(!preg_match($string_exp,$last_name)) { 
    $error_message .= 'The Last Name you entered does not appear to be valid.<br />'; 
    } 
    if(strlen($comments) < 2) { 
    $error_message .= 'The Comments you entered do not appear to be valid.<br />'; 
    } 
    if(strlen($error_message) > 0) { 
    died($error_message); 
    } 
    $email_message = "Form details below.\n\n"; 

    function clean_string($string) { 
     $bad = array("content-type","bcc:","to:","cc:","href"); 
     return str_replace($bad,"",$string); 
    } 

    $email_message .= "First Name: ".clean_string($first_name)."\n"; 
    $email_message .= "Last Name: ".clean_string($last_name)."\n"; 
    $email_message .= "Email: ".clean_string($email_from)."\n"; 
    $email_message .= "Telephone: ".clean_string($telephone)."\n"; 
    $email_message .= "Comments: ".clean_string($comments)."\n"; 

    echo "<br>"; 
    echo $email_from + $email_to + $email_message; 
     echo "<br>"; 

// create email headers 
$headers = 'From: '.$email_from."\r\n". 
'Reply-To: '.$email_from."\r\n". 
'X-Mailer: PHP/' . phpversion(); 
@mail($email_to, $email_subject, $email_message, $headers); 
} 
?>

当我从phpmyadmin运行它，它显示0在页面的左上角。我检查了short_tag，重新启动服务器两次。但没有结果。我能做什么？

什么是您的页面的文件名？ – 2012-04-11 07:55:54

等等..你是什么意思“当我从phpmyadmin运行这个”？你正在phpmyadmin中运行这些代码？ – 2012-04-11 07:55:57

你的add_handler指令是什么样的？ – 2012-04-11 07:56:05

你很混淆字符串串联如何与JavaScript一起工作。我的意思是这条线：

echo $email_from + $email_to + $email_message;

与

echo $email_from . $email_to . $email_message;

谢谢，那是我的错误，但这并没有帮助恢复主要问题。 – 2012-04-11 08:38:46

做一个phpinfo.php的文件和下面的代码添加到它：

phpinfo();

如果你仍然能看到代码，重新安装wampserver，确保Apache服务器正在运行。

忘了提及，运行phpinfo.php文件后，你上传到你的根文件夹 – John 2012-04-11 08:11:59

我做到了。但仍然相同。该页面显示相同的脚本。 :( – 2012-04-11 08:36:33

然后可能是你的wamp服务器配置不正确，请尝试重新安装并确保Apache服务正在运行，你的代码没问题， – John 2012-04-11 08:41:30

支票空格

也替换它 - 从你的PHP文件的末尾删除>，这也可能导致输出错误
