【thinkphp5框架的目录结构，以及使用框架model 、controler、view的使用，以及错误调试和日志记录】
thinkphp5 在php5.5版本以上”no input file specified“问题解决：
public/.htaccess文件中的
rewriterule ^(.*)$ index.php/$1 [qsa,pt,l]
在默认情况下会导致no input file specified.
修改成
rewriterule ^(.*)$ index.php [l,e=path_info:$1]
问题解决
配置文件的使用
application/index.controller/demo.php
<?php
namespace app\index\controller;
use think\config;
class demo extends base{
// 配置文件的使用
public function config() {
// 默认一页显示15条
$config = config::get("paginate");
dump($config);//15
$config = config("paginate.type");
dump(config("?paginate"));//boolean true
$config = config("paginate.type");
dump(config("?paginate111"));//boolean false
dump(config::has("paginate"));//boolean true
dump(config("cyy"));
// array (size=1)
// cyy' => int 1
dump(config("redis.host"));//string '127.0.0.1'
}
}
application/extra/redis.php
<?php
// 配置文件的使用
return [
"host" => "127.0.0.1",
];
application/index/config/php
<?php
// 配置文件的使用
return [
"cyy" => [
'cyy' => 1,
]
];
路由的使用
自定义路由
application/index/controller/video.php
<?php
namespace app\index\controller;
class video extends controller {
// 自定义路由
public function getvideo() {
$id = input("param.id");
// http://phptest.com/index/video/getvideo?id=2
// => 域名/video/2
dump($id);
}
}
application/route.php

use think\route;
// 自定义路由 域名/video/2
// route::rule("video/:id", "index/video/getvideo");
//route::get("video/:id", "index/video/getvideo");// 定义get请求路由
//route::post("video/:id", "index/video/getvideo");// 定义post请求路由
// 组合写法
route::get([
'video/:id' => ["index/video/getvideo", [], ['id' => '\d+']],
]);
控制器的使用
application/index/controller/demo.php
<?php
namespace app\index\controller;
use think\config;
use think\request;
class demo extends base{
/**
* 初始化
* @auth cyy
* @return [type] [description]
*/
public function _initialize() {
dump("这是initialize");
}
public function test() {
// 数组转json格式返回
return json(["as" => 1, "cyy" => "test"]);
}
public function hello() {
var_dump(input("param."));
return "index-index-hello";
}
// 控制器-跳转
public function abc() {
$id = input("param.id", 0, "intval");
if($id == 1) {
$this->success("操作成功", "admin/index/index");
}elseif($id == 2) {
$this->error("操作失败");
}
}
// 控制器-重定向
public function ef() {
$this->redirect("hello", ["id" => 1, "ms" => 123]);
//redirect("https://baidu.com");
}
// 控制器-请求
public function requestdata() {
$request = request::instance();
//访问http://phptest.com/index/demo/requestdata?ids=2
dump(request()->ispost());//boolean false
dump(input("?get.ids"));//boolean true
dump(request()->has("ids", "get"));//boolean true
}
}
application/index/controller/base.php
<?php
namespace app\index\controller;
use think\controller;
class base extends controller {
/**
* 空操作
* @auth singwa
* @param [type] $name [description]
* @return [type] [description]
*/
// 控制器-空操作
public function _empty($name) {
// todo
return $name;
}
}
