关于PHP模板Smarty的初级使用方法以及心得分享
本篇文章是对PHP模板Smarty的初级使用方法以及心得进行了详细的分析介绍,需要的朋友参考下
至于怎么配置,这里就不用多说了,网上一大堆。
1.基本上要用到的最主要的方法就是assign和display方法。
2.基本上在页面上要用到的知识就是if和foreach和section这三个。
3.基本上最难的就是foreach和section。
4.初学的时候老是循环不出自己想要的数据。因为感觉还是跟php啊java啊这些的foreach和for都有些差别的。很难抓住他的活动路径,很难调试他的数据。
5.所以这里,我把一点点经念放出来:
如果数据是这样:
复制代码 代码如下:
array(0=>array('id'=>'1111','content'=>'2222'));那么foreach循环
{{foreach from=$exam item=item key=k}}
{{$item.content}}
{{/foreach}}
就可以了,但是如果是array('id'=>'1111','content'=>'2222')这样,就不可以这样循环了,需要这样:
复制代码 代码如下:
{{foreach from=$exam item=item key=k}}
{{if $k eq 'content'}}
{{$item}}
{{/if}}
{{/foreach}}
这里如果不了解eq是什么意思,可以网上搜下,下面我把这个给稍微罗列下:
eq相等,
ne、neq不相等,
gt大于,
lt小于,
gte、ge大于等于,美国空间,
lte、le 小于等于,
not非, mod求模。
is [not] div by是否能被某数整除,香港服务器,
is [not]even是否为偶数,
$a is [not] even by $b即($a / $b) % 2 == 0,
is [not] odd是否为奇
6.在smarty的模板里面如果要使用php代码,这样:
{{php}}$a = "gayayang"; echo $a;{{/php}}
这样就可以在模板里面使用php代码了。
7.在smarty里面引用文件:
可以用上面的办法:{{php}}include "config.php";{{/php}}
或者专业一点:{{include file="config.php"}}
两个方法都可以实现。下面的比较专业点,推荐。
8.有个这样的方法:$smarty->fetch("mytemplate.html");
fetch和display都是渲染模板用的.fetch可以将渲染后的整个模板以字符串的形式赋值给一个变量,可以用作生成静态页用
现在知道这个怎么用了吧,他可以返回文件的内容给一个变量,那这个就非常有用咯。呵呵
使用fetch函数,你可以将要输出的html赋值给一个变量,可以对里面的数据进行一些输出,再将他输出。
smarty中的display方法,实际上调用的就是fetch,只不过是直接将他显示出来而已,而fetch默认是不显示,香港服务器租用,返回给一个变量的。
基本上也就这么些了,以后有补充了再来写吧。呵呵

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,
