Question

我的php文件是：

<?php
session_start();

    if (!class_exists('FacebookApiException')) {
    require_once('facebook.php' );
    }
        $facebook = new Facebook(array(
        'appId' => $appId,
        'secret' => $appSecret,
    ));
    $fbuser = $facebook->getUser();
 if ($fbuser) {
        try {
         $user_interest = $facebook->api('/me/movies');
        echo '<pre>';
        //print_r($user_interest);
        }
 catch (FacebookApiException $e) {
    echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
    $user = null;
  }}
?>

我想在php文件中使用$ user_interest和html代码中的其他var：我试着按照以下方式给出错误$ user_interest not defined。

<?php
session_start();
$appId = '619'; 
$appSecret = 'myverybeatuifuldaisygiveusmilk'; // Facebook App Secret
$return_url = 'http://yoursite.com/connect_script/';  //path to script folder
$fbPermissions = 'publish_stream,email'; //more permissions : https://developers.facebook.com/docs/authentication/permissions/
require_once('facebook.php' );
$facebook = new Facebook(array(
        'appId' => $appId,
        'secret' => $appSecret,
    ));
    $fbuser = $facebook->getUser();
     $user_interest = $facebook->api('/me/movies');
?>

Answer 1

尝试更改行

console.log($user_interest);

为：

console.log('<?php echo $user_interest; ?>');

Answer 2

您正在使用php上下文之外的变量$ user_interest。它应该放在php-Tags中，如此：

<?php echo $user_interest; ?>

在html页面中包含php文件的内容
