php代碼顯示，而不是運行

我使用php 5.2.4與wampserver。一切都很順利。幾天後我做了幾件作品。沒有問題。php代碼顯示，而不是運行

但是我面臨着一個奇怪的問題。我爲頁面編寫的腳本顯示而不是渲染的網頁。我的頁面在這裏給出：

<?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); 
} 
?>

當我從phpmyadmin運行它，它顯示0在頁面的左上角。我檢查了short_tag，重新啓動服務器兩次。但沒有結果。我能做什麼？

什麼是您的頁面的文件名？ – 2012-04-11 07:55:54

等等..你是什麼意思「當我從phpmyadmin運行這個」？你正在phpmyadmin中運行這些代碼？ – 2012-04-11 07:55:57

你的add_handler指令是什麼樣的？ – 2012-04-11 07:56:05

你很混淆字符串串聯如何與JavaScript一起工作。我的意思是這條線：

echo $email_from + $email_to + $email_message;

與

echo $email_from . $email_to . $email_message;

謝謝，那是我的錯誤，但這並沒有幫助恢復主要問題。 – 2012-04-11 08:38:46

做一個phpinfo.php的文件和下面的代碼添加到它：

phpinfo();

如果你仍然能看到代碼，重新安裝wampserver，確保Apache服務器正在運行。

忘了提及，運行phpinfo.php文件後，你上傳到你的根文件夾 – John 2012-04-11 08:11:59

我做到了。但仍然相同。該頁面顯示相同的腳本。 :( – 2012-04-11 08:36:33

然後可能是你的wamp服務器配置不正確，請嘗試重新安裝並確保Apache服務正在運行，你的代碼沒問題， – John 2012-04-11 08:41:30

支票空格

也替換它 - 從你的PHP文件的末尾刪除>，這也可能導致輸出錯誤

？
