学习了PHP很长时间了,这里和大家一起分享一下小经验。PHP是一种用于创建动态WEB页面的服务端脚本语言。如同ASP和ColdFusion,用户可以混合使用PHP和HTML编写WEB页面,当访问者浏览到该页面时,服务端会首先对页面中的PHP命令进行处理,然后把处理后的结果连同HTML内容一起传送到访问端的浏览器。

但是与ASP或 ColdFusion不同,PHP是一种源代码开放程序,拥有很好的跨平台兼容性。用户可以在Windows NT系统以及许多版本的Unix系统上运行PHP,而且可以将PHP作为Apache服务器的内置模块或CGI程序运行。除了能够精确的控制WEB页面的显示内容之外,用户还可以通过使用PHP发送HTTP报头。用户可以通过PHP设置cookies,管理用户身份识别,并对用户浏览页面进行重定向。PHP具有非常强大的数据库支持功能,能够访问几乎目前所有较为流行的数据库系统。此外,PHP可以与多个外接库集成,为用户提供更多的实用功能,如生成PDF文件等。

用户可以直接在WEB页面中输入PHP命令代码,因而不需要任何特殊的开发环境。在WEB页面中,所有PHP代码都被放置在“”中。此外,用户还可以选择使用诸如等的形式。PHP引擎会自动识别并处理页面中所有位于PHP定界符之间的代码。PHP脚本语言的语法结构与C语言和Perl语言的语法风格非常相似。用户在使用变量前不需要对变量进行声明。使用PHP创建数组的过程也非常简单。PHP还具有基本的面向对象组件功能,可以极大的方便用户有效组织和封装自己编写的代码。今天为大家介绍一个PHP星期几获取的方法,希望对大家有帮助。

PHP星期几获取代码:
<ol class="dp-xml">
<li class="alt"><span><span>date("l");  </span></span></li>
<li class=""><span>//data就可以获取英文的星期比如Sunday  </span></li>
<li class="alt"><span>date("w");  </span></li>
<li class=""><span>//这个可以获取数字星期比如123,注意0是星期日 </span></li>
</ol>
Copy after login

获取中文星期可以这样

<ol class="dp-xml">
<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">weekarray</font></span><span>=array("日","一","二","三","四","五","六");  </span></span></li>
<li class=""><span>echo "星期".$weekarray[date("w")]; </span></li>
</ol>
Copy after login

获取指定日期是:

<ol class="dp-xml">
<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">weekarray</font></span><span>=array("日","一","二","三","四","五","六");  </span></span></li>
<li class=""><span>echo "星期".$weekarray[date("w","2011-11-11")]; </span></li>
</ol>
Copy after login

因为date函数非常强大,他完全可以胜任一切这样的工作我附个手册里的表吧

<ol class="dp-xml">
<li class="alt"><span><span>a - "am" 或是 "pm"   </span></span></li>
