聊天室技术(六)-- 表情和动作_PHP

表情和动作极大的丰富了聊天的乐趣,一般的聊天室主要通过2种方法发送
(1) 按钮菜单的方法
通过在一个固定的下拉菜单里面进行选择,找到自己满意的表情,然后选中,按发送按钮发出
(2) 通过手工输入代号
比如网易的以手工输入 //hello 代表欢迎的一段动作,以 //bye 代表再见的一段动作表情

 

我们这里介绍菜单的具体实现方法,手工输入的不用介绍了吧! 哈哈!除非你记不住那些...

1 下拉菜单选择表情动作的实现
为了扩充方便,我们制作了表情动作的数据文件,这样在以后扩充时将会非常方便.

表情动作文件的格式如下($split代表分割符):

//1234$split“1234567,我的朋友在哪里1234!!!!!”
//?$split很疑惑的看着对象...
//??$split抓呀抓,把头皮都抓破了,也没有想出个所以然来。
//???$split怎么回事?这到底是怎么回事

前面的//1234代表表情动作代码,分隔符后面的代表显示的表情动作注意其中的 对象 两个字将会在显示时替换成为发言对象的名字

这段代码用于把菜单选择的对应的表情动作代码写到发送栏里面
<script> <br>function changemote($newemote) <br>{ <br>document.inputform.msg.value = $newemote <br>} <br></script>

这段代码生成动态下来菜单


这样就完成了从菜单选动作表情的过程


2 表情动作在发言处理程序里的处理过程

messagesend.php

//读入表情动作文件
$emote3 = file($emotefilename);
$emote3number = count($emote3);
for($kk=0;$kk<$emote3number;$kk++)
{

//分割每个表情动作
$emote=split($split,chop($emote3[$kk]),99);

//如果发言内容等于表情动作
if($message == $emote[0])
{

//替换表情动作里面的 对象 为实际的聊天对象名字
$emote[1]=ereg_replace("对象","$talkto",$emote[1]);

//发言内容改为动作表情的内容
$message = "$name>".$emote[1];
break;
}
}
?>

这样我们就实现了表情和动作,如果做一个自动添加动作表情的程序功能,更会增加聊天的娱乐性!

What are Weak References in PHP and when are they useful?What are Weak References in PHP and when are they useful?Apr 12, 2025 am 12:13 AM

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP vs. Python: Understanding the DifferencesPHP vs. Python: Understanding the DifferencesApr 11, 2025 am 12:15 AM

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP: Is It Dying or Simply Adapting?PHP: Is It Dying or Simply Adapting?Apr 11, 2025 am 12:13 AM

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The Future of PHP: Adaptations and InnovationsThe Future of PHP: Adaptations and InnovationsApr 11, 2025 am 12:01 AM

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

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),
