高手指点PHP星期几获取方法
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。
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>
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>
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>
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> <li class=""><span>A - "AM" 或是 "PM" </span></li> <li class="alt"><span>d - 几日,二位数字,若不足二位则前面补零; 如: "01" 至 "31" </span></li> <li class=""><span>D - 星期几,三个英文字母; 如: "Fri" </span></li> <li class="alt"><span>F - 月份,英文全名; 如: "January" </span></li> <li class=""><span>h - 12 小时制的小时; 如: "01" 至 "12" </span></li> <li class="alt"><span>H - 24 小时制的小时; 如: "00" 至 "23" </span></li> <li class=""><span>g - 12 小时制的小时,不足二位不补零; 如: "1" 至 12" </span></li> <li class="alt"><span>G - 24 小时制的小时,不足二位不补零; 如: "0" 至 "23" </span></li> <li class=""><span>i - 分钟; 如: "00" 至 "59" </span></li> <li class="alt"><span>j - 几日,二位数字,若不足二位不补零; 如: "1" 至 "31" </span></li> <li class=""><span>l - 星期几,英文全名; 如: "Friday" </span></li> <li class="alt"><span>m - 月份,二位数字,若不足二位则在前面补零; 如: "01" 至 "12" </span></li> <li class=""><span>n - 月份,二位数字,若不足二位则不补零; 如: "1" 至 "12" </span></li> <li class="alt"><span>M - 月份,三个英文字母; 如: "Jan" </span></li> <li class=""><span>s - 秒; 如: "00" 至 "59" </span></li> <li class="alt"><span>S - 字尾加英文序数,二个英文字母; 如: "th","nd" </span></li> <li class=""><span>t - 指定月份的天数; 如: "28" 至 "31" </span></li> <li class="alt"><span>U - 总秒数 </span></li> <li class=""><span>w - 数字型的星期几,如: "0" (星期日) 至 "6" (星期六) </span></li> <li class="alt"><span>Y - 年,四位数字; 如: "1999" </span></li> <li class=""><span>y - 年,二位数字; 如: "99" </span></li> <li class="alt"><span>z - 一年中的第几天; 如: "0" 至 "365" </span></li> </ol>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
