Linux 全局安装 composer 将目录切换到/usr/local/bin/目录
cd /usr/local/bin/
在 bin 目录中下载 composer
curl -sS https://getcomposer.org/installer | php
通过 composer.phar -v 查看 composer
修改为中国镜像
composer.phar config -g repo.packagist composer https:packagist.phpcomposer.com
最后我把composer.phar复制了一份，重命名为composer
以后可以直接用composer
MVC架构模式 实现简易模板引擎： composer.json {
自动加载
可以在composer.json的autoload字段找那个添加自己的autoloader
"autoload": {
psr-4: {
AppControllers": Controllers/,AppModelsModels/ToolsTools/
}
}
}
Models/Users.php <?php
model层数据库操作演示
namespace AppModels;
class Users
{
数据存入数据库演示
public function store()
{
echo 'store into database';
}
查询数据库演示
function getUsername()
{
查询数据库
return test-data;
}
}
Controllers/UserController.php <? AppControllers;
use ToolsTpl;
use AppModelsUsers;
UserController extends Tpl
{
function create()
{
echo User create function getUser()
{
通过Model查询数据
$userModel = new Users;
$username = $userModel->getUsername();
将$username显示在对应的一个HTML文件当中，并且显示出来
表现层 user/user.html
将变量发送给模板（html文件）
$this->assign(usernameage',20);
显示模板
$this->display(user/user.html);
}
}
Views/user/user.html <!DOCTYPE html>
<html lang=en">
<head>
<meta charset=UTF-8">
<title>Title</title>
</head>
<body>
<h2>
{$username}
</h2>
<h3>
{$age}
</h3>
</body>
</html>
Tools/Tpl.php <? 分配变量
将变量发送给模板
Tools;
Tpl
{
protected $assign_vars = [];
function assign($tpl_var_name,$val)
{
$this->assign_vars[$tpl_var_name] = $val;
}
function display($tpl_name)
{
Views/user/$tpl_name
$className = get_called_class(); AppControllersUserController
$dirName = strtolower(substr(substr($className,1)">16),1)">0,-10)); user
$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[""]; ?> 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 服务端开发部分演示
<?/**
* Created by PhpStorm.
*/
session_start();
require './libs/Smarty.class.php';
$smarty = Smarty();
简单配置 初始化设置
$smarty->setTemplateDir('./Views');
$smarty->setCompileDir('./runtime/Compile'$smarty->setConfigDir('./Config'$smarty->addPluginsDir('./Plugins'$smarty->setCacheDir('./runtime/Cache');
$smarty->caching = 1;开启缓存
$smarty->setCacheLifetime(60*60*24$smarty->left_delimiter = '{';
$smarty->right_delimiter = '}';
缓存机制
if (!$smarty->isCached('extends.html',1)">$_SERVER['REQUEST_URI'])) {
数据库查询
$data = [[]];
使用
$smarty->assign([
'username' => 'test-data','age' => 20
]);
数组
$smarty->assign('arr1',[1,2,3]);
$smarty->assign('arr2',['id' => 1,'username' => 'zhangsan','age' => 30$smarty->assign('users', [
['id' => 1,'age' => 30],1)">
['id' => 2,'username' => 'lisi','age' => 40]
]);
$smarty->assign('hobby_ids',1)">$smarty->assign('hobby_output',['看书','敲代码','看视频'$smarty->assign('options',1)"> [
1 => '看书',2 => '敲代码',3 => '看视频' 注册function
$smarty->registerPlugin('function','font',1)">function ($attributes) {
$text = $attributes['text'];
$color = $attributes['color'] ?? 'black';
return '<span style="color: ' . $color . '">' . $text . '</span>';
});
注册变量修饰器
$smarty->registerPlugin('modifier','link',1)">$text,1)">$href,1)">$isCapitalize = false$return = '<a href="' . $href . '">' . $text . '</a>'if ($isCapitalize) {
return ucwords($return);
}
;
});
注册块状函数
$smarty->registerPlugin('block',1)">$attributes,1)">$text$href = $attributes['href'];
if (!is_null()) {
return '<a href="' . ;
}
});
对象
$smarty->assign('obj',1)">$smarty);
$smarty->assign('text','This is a paragraph!'$smarty->display('smarty.html');
$smarty->display('loop.html'$smarty->display('single_tag_func.html'$smarty->display('modifier.html'$smarty->display('block_func.html'$smarty->display('plugins.html'$data);
}
$smarty->clearCache('extends.html',1)">]);
clearAllCache();
$smarty->display('extends.html',1)">$_SERVER['REQUEST_URI']);
