Making it testable and $_Server independent?

[Yauheni1]

Changes:

1) Single exception to catch on execution(Invalid parameter just to
make sure that class is used right).
2) Class can be used in CLI mode.
3) Class is fully testable.


<?php
class glue
{
public function __construct($request, $method)
{
$this->_request = $request;
$this->_method = $method;
}

public function exec()
{
foreach ($this->_urls as $regex => $class) {
$regex = str_replace('/', '\/', $regex);
$regex = '^' . $regex . '\/?$';
if (!preg_match("/$regex/i", $this->_request, $matches)) {
continue;
}

if (class_exists($class)) {
$obj = new $class;
if (method_exists($obj, $this->_method)) {
return $obj->{$this->_method}($matches);;
}
}
}

throw new UnexpectedValueException("URL, $path, not found.");
}

public function stick($urls)
{
if (!is_array($urls)) {
throw new InvalidArgumentException('Urls should be passed
as an array.');
}

$this->_urls = $urls;
return $this;
}

protected $_urls = array();
protected $_method;
protected $_request;
}

$urls = array(
'/' => 'index',
);

class index {
function GET() {
echo "Hello, World!" . PHP_EOL;
}
}

$app = new glue(
'/', //$_SERVER['REQUEST_URI']
'GET' //strtolower($_SERVER['REQUEST_METHOD'])
);

$app->stick($urls)->exec();

Nice changes.

If you use BitBucket, you could fork the Glue repo and host this
version in your own repo.

Thanks,
