Bob

Very basic routing class (about 103 lines) ...

tl;dr

Bob::get($pattern, $callback);

is short for

Bob::add('get', $pattern, $callback);

$method and $pattern can either be strings or arrays of strings. $callbacks are one or more functions or a class.

Bob::go($file);

Usage

Routes

Add a route:

Bob::get('/', function() {
	echo 'Hello World';
});

A little bit more:

Bob::get('/user/bob', function() {
	echo 'Hey, bob!';
});

Add a bunch of patterns:

Bob::get(['/', '/home'], function() {
	echo 'Hello World';
});

Use a function:

Bob::get('/user/:is_numeric', function($id) {
	echo 'Hello, '.$user[$id];
});

Use an own function:

Bob::get('/user/:is_user', function($user) {
	echo 'Hey, '.$user.'!';
});

function is_user($user) {
	return in_array($user, ['Justus', 'Peter', 'Bob']);
}

Negate:

Bob::get('/user/:is_user', function($user) {
	echo 'Hey, '.$user.'!';
});

Bob::get('/user/!is_user', function($user) {
	echo 'Can\'t find this user :(';
});

You can also use regex (in the same way you'd use a function):

Bob::$patterns = [
	'num' => '[0-9]+',
	'all' => '.*'
];

Bob::get('/:num', function($id) {
	echo $id;
});

Callbacks

Use multiple callbacks:

Bob::get('/user/:is_numeric', [function($id) {
	echo 'Hello, '.$user[$id];
}, count_login($id)]);

Multiple request methods:

Bob::add(['post', 'put'], '/user', function() {
	// Add a user! Or something else! I don't care!
});

A Class as Callback

Your can also use a class as callback. Just pass its name. Bob will try to execute $method on $callback, so something like this will work:

class SayHello {
	static function get($num) {
		for($i = 0; $i < $num; $i++)
			echo 'GET Hello!';
	}

	static function post($num) {
		for($i = 0; $i < $num; $i++)
			echo 'POST Hello!';
	}
}

Bob::add([], '/:is_numeric', 'SayHello');

Notice that you have to use Bob::add() with an empty array. In this case, you're not required to tell Bob the accepted HTTP methods, it'll just look inside the provided class.

Execute

With the use-an-own-function-example from above, the (second) final step could look like this:

Bob::go();

Or - if you'd like to work in a subdirectory - trim the request url:

Bob::go('/foo/bar.php');

http://localhost/foo/bar.php/user/1 => /user/1

If nothing was found

404:

Bob::summary(function($passed, $refused) {
	echo $passed.' routes passed, '.$refused.' were refused.';
});

This will only execute the callback, if no rule matched the request:

Bob::notfound(function($passed, $refused) {
	echo '404 :(';
});

You're done. Have a nice day.
