十六、造船和防御(FleetBuildingPage.php与DefensesBuildingPage.php页面)
先说造船厂页面,其实这个页面中并没有真正的造船,只是把要造的船和数量保存到数据库中;产生船舰的代码在另外一个函数里面。下面我们开始分析这个页面,并且也按照前面的思路,先讲解构造页面的代码。
首先判断本星球是否已有造船厂,没有当然要提示。
下面使用循环语句,构造出每种船舰的建造页面,这段代码我觉得不需要再详细讲解了。
接下来是要显示正在制造的船舰列表,要脚本动态显示,实际上是假像;即使显示有船舰造好了,如果不是刷新,数据库里面并不会有。注意这里有两个重要的字段:b_hangar_id保存着要造的船列表;b_hangar保存着上次更新后剩下的时间,单位是秒。
使用函数ElementBuildListBox(),构造出一个正在造船的脚本,函数代码大家自己看,不难,只要理解了前面我说的两个字段就可以了。
最后输出造船厂页面。
现在我们又回到前面,玩家输入要制造的船舰的数量,进入这段代码。
1.取得要制造的船舰代码和数量
2.判断制造的数量是否超过允许的最大值,超过则取最大值
3.如果制造数量不为零,判断是否允许制造
4.然后取得当前资源能制造的最大值
5.设置资源消耗和时间消耗
6.最后更新星球数据,包括减少资源和建造船舰的字段b_hangar_id,贴出代码如下:
if ($Count >= 1) { $CurrentPlanet['metal'] -= $Ressource['metal']; $CurrentPlanet['crystal'] -= $Ressource['crystal']; $CurrentPlanet['deuterium'] -= $Ressource['deuterium']; $CurrentPlanet['b_hangar_id'].= "". $Element .",". $Count .";"; }
造船厂页面完成了,下面我们来看防御页面。这个页面基本逻辑和造船厂一样,这里就不写了。不同的是多一些逻辑限制,罗列出来如下:
1.在构造防御单位页面的时候,代码407和408是大小防御护盾,要注意只能有一个
2.在玩家输入数量后的制造代码里面,代码502和503是拦截导弹和星际导弹,要注意两个导弹的数量关系和正在制造列表里面的导弹数量
3.同样使用字段b_hangar_id保存
造船和防御页面简单的讲解完了,最重要的制造代码在另外一个函数里面,下一章节分析。

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
