webman Quick Start Simple Example
Return String
Create Controller
Create the file app/controller/UserController.php as follows
<?php
namespace app\controller;
use support\Request;
class UserController
{
public function hello(Request $request)
{
$default_name = 'webman';
// Get the name parameter from the get request; if no name parameter is passed, return $default_name
$name = $request->get('name', $default_name);
// Return a string to the browser
return response('hello ' . $name);
}
}Access
Access http://127.0.0.1:8787/user/hello?name=tom in the browser
The browser will return hello tom
Return JSON
Modify the file app/controller/UserController.php as follows
<?php
namespace app\controller;
use support\Request;
class UserController
{
public function hello(Request $request)
{
$default_name = 'webman';
$name = $request->get('name', $default_name);
return json([
'code' => 0,
'msg' => 'ok',
'data' => $name
]);
}
}Access
Access http://127.0.0.1:8787/user/hello?name=tom in the browser
The browser will return {"code":0,"msg":"ok","data":"tom"}
Using the json helper function to return data will automatically add a Content-Type: application/json header.
Return XML
Similarly, using the helper function xml($xml) will return an xml response with a Content-Type: text/xml header.
The $xml parameter can be either an xml string or a SimpleXMLElement object.
Return JSONP
Similarly, using the helper function jsonp($data, $callback_name = 'callback') will return a jsonp response.
Return View
Modify the file app/controller/UserController.php as follows
<?php
namespace app\controller;
use support\Request;
class UserController
{
public function hello(Request $request)
{
$default_name = 'webman';
$name = $request->get('name', $default_name);
return view('user/hello', ['name' => $name]);
}
}Create the file app/view/user/hello.html as follows
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>webman</title>
</head>
<body>
hello <?=htmlspecialchars($name)?>
</body>
</html>Access http://127.0.0.1:8787/user/hello?name=tom in the browser, and it will return an HTML page with the content hello tom.
Note: Webman uses PHP's native syntax as the template by default. For other views, refer to View.
