Smarty basic syntax and three major variables of php

Smarty templates are mainly based on variables. Here are the three major variables of Smarty and some common usages

First, create the files to be used in the root directory, which are basically the same as last time. configs is the configuration folder

1. Variables allocated from PHP

Use $smarty->assign()

$smarty->display()

First write the initialization php code, which is the same as conn.inc.php in the previous article

<!--?php
    include "init.inc.php";
    //assign方法
    $smarty--->assign("title","11111111");
    $smarty->assign("content","2222222222");
    //分配一个关联数组,用的较少
    $smarty->assign(array("author"=>"何栘烽","time"=>date("Y-m-d H:i:s")));

    //注册函数
    $smarty->registerPlugin("function","myfun","test");  //注册插件，将test函数注册成myfun
    function test($args){
    	//args=array("size"=>7, "color"="yellow", "num"=>5, "connect"=>"3333333")
    	//循环遍历出
    	$str="";
    	for($i=0; $i<$args["num"]; $i++){
    		$str.=&#39;&#39;.$args["content"].&#39;
&#39;;
    	}
    	return $str;
    }
    //数组
    $smarty->assign("contacts",array("0575-1241243","kefeng.hyf@gmail.com", array("243214124", "45345")));
    //对象
    class Person{
    	public $name="kefeng";
    	function say(){
    		return $this->name."hhhhhhhh";
    	}
    }
    $smarty->assign("p",new Person());
    $smarty->display("demo.html");  //显示的模板

2. Read variables from the configuration file

Here you need to create a configs folder with the configuration file test.conf

test.conf:

bodycolor=#3e3e3e
bodybgcolor=yellow
border=10
align=center
width=800
bgcolor=gray

[index]
one=11111

[list]
two=22222

[content]
three=33333

Open session in demo.php

<!--?php include="" smarty-=""-->display("demo.html");  //显示的模板
<!--?php-->

Note: Load the configuration file: fa7a8c7840fbe9fb22722ebfeb11f235
Read:d29b9b54978ae4fe8cba6f3ef3d715e3
The second parameter is used to load the zone file: 4a6d016a925740c885c519d22d3901b5fa7a8c7840fbe9fb22722ebfeb11f235d29b9b54978ae4fe8cba6f3ef3d715e3d48d77c1a98479a300a419ed66d1dc18

demo.html: Here write some header files and loading code
