Simple Example
Return a String
Create a Controller
Create a new 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, and return $default_name if the 'name' parameter is not passed
$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 the Content-Type: text/xml
header.
The $xml
parameter can be an xml
string or a SimpleXMLElement
object.
Return JSONP
Similarly, using the helper function jsonp($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' => $name]);
}
}
Create a new file app/view/user/hello.html
as follows:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>webman</title>
</head>
<body>
hello <?=htmlspecialchars($name)?>
</body>
</html>
Access http://127.0.0.1:8787/user/hello?name=tom
in the browser
It will return an html page with the content hello tom
.
Note: By default, webman uses native PHP syntax as the template. If you want to use other views, see Views.
