smarty模板引擎之内建函数用法_PHP
本文实例讲述了smarty内建函数的使用方法。分享给大家供大家参考。具体如下:
in-build(内建),在smarty模板中,提供了很多内建的函数库,具体使用可以参考smarty中文手册chm版本。
1.foreach函数
操作数组如下:
//索引数组 $res=array('上海','北京','深圳'); $smarty->assign("arr",$res); //关联数组 $res2=array('city1'=>'北京','city2'=>'广州','city3'=>'湖南'); $smarty->assign("arr2",$res2); //索引二维数组 $res3 = array( array('潇晓','常山','吴蓓'),array('珊珊','常明') ); $smarty->assign("arr3",$res3); //关联二维数组 $res4 = array( array('id'=>'001','name'=>'张三','email'=>'zhangsan@1163.com'), array('url'=>'http://www.baidu.com','age'=>'28') ); $smarty->assign("arr4",$res4); //关联二维数组2 $res5=array( 'emp1'=>array('id'=>'001','name'=>'张三','email'=>'zhangsan@1163.com'), 'emp2'=>array('url'=>'http://www.baidu.com','age'=>'28') ); $smarty->assign("arr5",$res5);
遍历数组:
其中from、item、key是固定写法,key可以根据需求加
一维数组
索引数组:
<br/> <{foreach from=$arr item=temp}> <{$temp}> <t/> <{/foreach}> <br/>关联数组:<br/> <{foreach from=$arr2 item=temp key=k}> <{$k}>=<{$temp}><t/> <{/foreach}> <br/>
备注:from、item、key是固定的
二维数组
<br/>二维索引数组:<br/> <{foreach from=$arr3 item=temp key=k}> <{*这里的temp是一个数组*}> <{foreach from=$temp item=val}> <{$val}> <{/foreach}> <{/foreach}> <br/>二维关联数组格式1:<br/> <{foreach from=$arr4 item=temp}> <{*外层的键不需要,所以不添加key*}> <{foreach from=$temp item=val key=k}> <{*内层的键需要,添加key*}> <{$k}>=<{$val}> <{/foreach}> <{/foreach}> <br/>二维关联数组格式2:<br/> <{foreach from=$arr5 item=temp key=k}> <{$k}>: <{foreach from=$temp item=val key=k2}> <{$k2}>=<{$val }> <{/foreach}> <br/> <{/foreach}>
2.if...else...
<{if $age>10 }> 年龄大于10,年龄为:<{$age}> <{else}> 年龄小于10,年龄为:<{$age}> <{/if}>
3.if...elseif...elseif...else...
已知数据源如下:
$res4 = array( array('id'=>'001','age'=>'4'), array('id'=>'002','age'=>'16'), array('id'=>'003','age'=>'20'), array('id'=>'004','age'=>'80') );
模板中引用如下:
<{foreach from=$arr4 item=temp }> <{if $temp.age < 5}> <{$temp.id}>,你是小孩 <{elseif $temp.age >=5 and $temp.age <= 18}> <{$temp.id}>,你是年轻人 <{elseif $temp.age > 18 and $temp.age <= 50}> <{$temp.id}>,你是成年人 <{else}> <{$temp.id}>,年龄<span style="font-family:Consolas;">比较大了</span> <{/if}> <{/foreach}
希望本文所述对大家的php程序设计有所帮助。

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,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
