Question

我有一个网页，页面分为3个内容

PHP库/类（PHP包含文件）＆＃34;内部图书馆＆＃34; function FooFunction(){}

<html>

Header Bar (PHP Include File)
   Inside "Header Bar"  `<li>$Foo -> FooFunction();</li>`
Header (PHP Include File)
...Rest of Webpage...
Footer (PHP Include File)

</html>

由于某种原因，我的页面停止在执行或调用Foo函数的Header Bar处加载。该函数应该像HTML一样回显HTML：

if($User->getUsersName()){
    echo '<a href="#">'.$User->getUsersName().'</a>';
} else{
    echo '<a href="/login.php?return_url=&ref=net_bar&amp;method=network">log in</a>';
}

在这里编辑更详细的代码：

的index.php

<?php require("engine/network_system.php");
    $Network=new Network();
    $Network->setSession();

    if($Network->isSessionSet()){
        $User= new NetworkUser($_SESSION['network_id']);
    }
?>
<!DOCTYPE html>
<html lang="en">
    <head>
        <title>Sample</title
    </head>
    <body>
        <div id="pageWrapper" class="wrapper">
        <?php 
            require("includes/normalize.php");
            require("includes/network-bar.php");
              require("includes/header.php");
        ?>
</body>
</html>

类（在包含文件网络系统中）

<?php

    require("database-classes.php");

    class Network {

        function __construct(){

            $Database= new Database;
            $Database->getConnection();
            $Database->startConnection();
            $this->endConnection=$Database->endConnection();
        }

        function isSessionSet(){

            if(!isset($_SESSION['network_id'])){

                return false;
            }
            return true;
        }

        function setSession(){
            if(!isset($_SESSION)){
                session_start();
            }
        }
    }

    class NetworkUser {

        function __construct($networkId){

            $this->networkId=$networkId;    
        }


        // Getters
        function getNetworkId(){

            return $this->networkId;
        }

        function getUsersName(){

            $queryName=mysql_query("SELECT network_profile.first_name, network_profile.last_name
            FROM network_users, network_profile
            WHERE network_users.network_id=network_profile.network_id
            AND network_users.network_id='$this->networkId'
            LIMIT 1");

            if(mysql_num_rows($queryName)==1){

                $nameInfo=mysql_fetch_array($queryName);
                $firstName=$nameInfo['first_name'];
                $lastName=$nameInfo['last_name'];
                $usersName=$firstName.' '.$lastName;

                return $usersName;
            } else {

                return false;
            }
        }

        function getDisplayName(){
        }

        private $networkId, $firstName, $lastName;

    }
?>

数据库类

<?php

    class Database {
        public function __construct(){

            Private Info That DOES WORK


        }

        //Connections
        public function getConnection(){

            if($this->dbconnect_settings == NULL)
                return mysql_connect($this->dbhost, $this->dbusername, $this->dbpassword);
            else
                return $this->dbconnect_settings;
        }

        public function startConnection(){

            if(!$this->getConnection()){
                die('Could not connect to database'.mysql_error());
            }
            else{
                mysql_select_db($this->dbdatabase, $this->getConnection());
            }
        }

        public function endConnection(){
            if(!($this->getConnection())){
                echo -1;
            }
            else{

                mysql_close($this->getConnection());

            }
        }


        private $dbusername, $dbpassword, $dbhost, $dbdatabase, $dbconnect_settings=NULL;
    }

/*  $test= new Database();

    $test->startConnection();
    $test->endConnection();*/
?>

PHP脚本和页面不会继续加载
