Afro

A PHP class for handling URL requests, similar to Ruby's Sinatra gem.

Working with Afro

Afro includes five procedural functions which allow you to handle requests with:

• get
• post
• put
• delete
• ajax

All of them take the same parameters but will only activate on the given request types.

Handling a simple GET request with no parameters.

get('/', function($Afro) {
    echo "HELLO";
});

Handling a GET request for getting a users name.

get('/hello/(.*?)', function($Afro) {
	echo 'Hello ' . $Afro->param(2) . ', I hope today is full of Unicorns.'
});

Handling a GET request for getting a users name in different formats.

One of the beautiful things about Afro is that you can use the same request handler, but output different data depending on the format the request is called as.

Let's take the example above and use add a JSON output.

get('/hello/(.*?)', function($Afro) {
	$Afro->format('json', function($Afro) {
        echo json_encode(array('name', $Afro->param(2)));
    });

    if(!$Afro->format)
		echo 'Hello ' . $Afro->param(2) . ', I hope today is full of Unicorns.'
});

Now, if the request ends is http://localhost/afro/hello/jbrooksuk.json the output will be returned as a valid JSON string.

## Handling a simple POST request with a username.

post('/connect/(.*?)', function($Afro) {
    if(!$Afro->format)
    	// Insert the user into a database? The format will always be the same in whichever function you use.
});

Payload

Afro is also aware of requests which aren't handled by one of the five router functions. If you're request is in the format of ?hello=James&day=Sunday for example, then Afro will create an array of this in the payload array for you.

This can be accessed with $Afro->payload just in case you need it.

Exposing Afro

You can expose any part of Afro by taking a look at the instance created by the class on the $Afro variable. Calling var_dump($Afro->getInstance()) will display the current pages requested data along with several other useful elements.

• URI the entire URI being requested.
• params an array of params, accessible with the $Instance->param($index) function.
• method a string representation of the requested method used.
• format if a format such as .json or .csv is appended to the end of the URI this will be populated.
• paramCount the amount of parameters being requested in the params array above.
• payload as explained in the section above.
