linux 全局安装 compor
将目录切换到/usr/local/bin/目录 cd /usr/local/bin/在 bin 目录中下载 compor curl -ss /d/file/titlepic/installer | php通过 compor.phar -v 查看 compor修改为中国镜像 compor.phar config -g repo.packagist compor https://packagist.phpcompor.com最后我把compor.phar复制了一份，重命名为compor以后可以直接用compor
mvc架构模式
控制器（controller）- 负责转发请求，对请求进行处理
视图（view） – 界面设计人员进行图形界面设计
模型（model） – 程序员编写程序应有的功能（实现算法等等）、数据库专家进行数据管理和数据库设计(可以实现具体的功能)
实现简易模板引擎：
compor.json
{ // 自动加载 // 可以在compor.json的autoload字段找那个添加自己的autoloader "autoload": { "psr-4": { "app\\controllers\\": "controllers/", "app\\models\\": "models/", "tools\\": "tools/" } } }models/urs.php
<?php // model层数据库操作演示 namespace app\models; class urs { // 数据存入数据库演示 public function store() { echo 'store into databa'; } // 查询数据库演示 public function geturname() { // 查询数据库 return 'test-data'; } }controllers/urcontroller.php
<?php namespace app\controllers; u tools\tpl; u app\models\urs; class urcontroller extends tpl { public function create() { echo 'ur create'; } public function getur() { // 通过model查询数据 $urmodel = new urs; $urname = $urmodel->geturname(); // 将$urname显示在对应的一个html文件当中，并且显示出来 // 表现层 ur/ur.html // 将变量发送给模板（html文件） $this->assign('urname', $urname); $this->assign('age', 20); // 显示模板 $this->display('ur/ur.html'); } }views/ur/ur.html
发誓英文 <!doctype html> <html lang="en"> <head> <meta chart="utf-8"> <title>title</title> </head> <body> <h2> {$urname} </h2> <h3> {$age} </h3> </body> </html>tools/tpl.php
<?php // 分配变量 // 将变量发送给模板 namespace tools; class tpl { protected $assign_vars = []; public function assign($tpl_var_name, $val) { $this->assign_vars[$tpl_var_name] = $val; } public function display($tpl_name) { // views/ur/$tpl_name $classname = get_called_class(); // app\controllers\urcontroller $dirname = strtolower(substr(substr($classname, 16), 0, -10)); // ur $dir = dirname(__dir__) . '/views/' . $dirname . '/' . $tpl_name; // file_get_contents $content = file_get_contents($dir); // preg_replace foreach ($this->assign_vars as $tpl_var_name => $val) { $content = preg_replace('/\{$' . $tpl_var_name . '\}/', '<?php echo $this->assign_vars["' . $tpl_var_name . '"]; ?>', $content); } // compile $compile = dirname(__dir__) . '/runtime/compile/' . md5($tpl_name) . '.php'; file_put_contents($compile, $content); // include include $compile; } }smarty模板引擎的使用

1、使用registerplugin( )方法扩充插件格式
2、在smarty模板的libs/plugins/目录下创建函数插件文件
block.link.php
function smarty_block_link($attributes, $text){ $href = $attributes['href']; if (!is_null($text)) { return '<a href="' . $href . '">' . $text . '</a>'; }}function.font.php
function smarty_function_元旦节手抄报 简单font($attributes){ $text = $attributes['text']; $color = $attributes['color'] ?? 'black'; return '<span style="color: ' . $color . '">' . $text . '</span>';}modifier.link.php
function smarty_modifier_link($text, $href, $iscapitalize = fal){ $return = '<a href="' . $href . '">' . $text . '</a>'; if ($iscapitalize) { return ucwords($return); } return $return;}模板继承的使用
extends.html
!-- 使用{extends}函数实现模板继承合并子模板和父模板的{block}标签内容 -->{extends file="layout.html"}{block name="title"} article {$smarty.block.parent}{/block}{block name="content"} article list {$smarty.get.page} {*nocache*} {time()} {*/nocache*} {time()|date_format:'%h:%m:%s' nocache}{/block}layout.html

开启缓存
$smarty -> caching = 1|2|0;
$smarty -> tcachedir(“./cache”);
$smarty->tcachelifetime(300); // 5分钟，以秒为单位，-1永不过期
$smarty -> display(‘index.tpl’);
$smarty -> display(‘index.tpl’, $_rver[‘request_uri’]);
相关函数
iscached()
clearcache()
clearallcache()
