今天小编跟大家分享一下tp5的简单的增删改查和一个数据输出；废话不多，上代码
控制器方法代码
index.php
<?php
namespace app\index\controller;
use think\Controller;

use think\Log;
header("Content-type:text/html;charset=UTF-8");
class Index extends Controller
{
//渲染首页输出信息
public function index()
{
if(request()->isPost()){
$a=input('search');
$result = db('work')->where('sex',$a)->select();
}else{
$result = db('work')->select();
}
return $this->fetch('index',array('a'=>$result));
}
//添加信息
public function insert()
{
return view('insert');
}
public function insertdo()
{
$data = input('post.');
$sql = db('work')->insert($data);
if($sql){
$this->success('新增成功', 'Index/index');
}else{
return $this->error('添加失败！');
}
}
//修改信息
public function updete()
{
$info = Db::table('work')->where('id',input('id'))->find();
return $this->fetch('updete',array('info'=>$info));
}
public function updetedo()
{
$data['num'] = input('num');
$data['name'] = input('name');
$data['sex'] = input('sex');
$data['phone'] = input('phone');
$data['que'] = input('que');
$res = Db::table('work')->where('id',input('post.id'))->update($data);
if($res){
$this->success('更新成功','index');
}else{
$this->error('更新失败！');
}
}
//删除信息
public function deletes()
{
$res = Db::table('work')->where('id',input('id'))->delete();
if($res){
$this->success('删除成功！','index');
}else{
$this->error('删除失败！');
}
}
//搜索信息导出
public function indexdo()
{
$a=input("fed");
$b=explode(',',$a);
$va = [];
if(count($b) > 1){
foreach($b as $v){
$where['id'] = $v;
$va[] = db('work')->where($where)->find();
}
}else{
$va = db('work')->select();
}
//var_dump($va);exit;
$strTable ='<table border="1">';

小编建议：PHP初学者的话，要不想一下，先按自己的想法过一遍，试一下，是否行的通，要多试，多想！！！！
