route_to() function not work if greater than 3 parameters.

[HieuPT7]

Hi
In file router.php

$routes->get('test/(:segment)/(:segment)', 'TestController::�index/$1/$2', ['as' => 'testRouter']);

In controller:
echo route_to('testRouter', 1, 2);
or use redirect()->route('testRouter', [1, 2]);

Expected result:
/test/1/2

Actual result:
/test/1/1

Thanks

The replacement is occurring because of the same pattern:

https://github.com/bcit-ci/CodeIgniter4/blob/74e95d35edf38b6d3244cf862186454a5df67fdb/system/Router/RouteCollection.php#L1132-L1135

Test:

$routes->get('test/(:any)/(:segment)', 'TestController::index/$1/$2', ['as' => 'testRouter']);

Maybe preg_replace helps.

[natanfelles]

This solves:

CodeIgniter4/system/Router/RouteCollection.php:1132

if (preg_match("|{$pattern}|", $params[$index]))
{
	$pos = strpos($from, $pattern);

	if ($pos !== false)
	{
		$from = substr_replace($from, $params[$index], $pos, strlen($pattern));
	}
}

Parameters ordering continues working in Controllers:

$routes->get('test/(:segment)/(:segment)/(:segment)', 'TestController::test/$2/$1/$3', ['as' => 'testRouter']);

http://localhost:8080/test/1/2/3

public function test($param1, $param2, $param3)
{
	var_dump($param1);
	var_dump($param2);
	var_dump($param3);
}
