PHP function to get url from route - php

Question

I have this class:
class Route
{
protected $routes = [
"view_article" => "view/{articleUrl}",
"edit_article" => "edit/{articleId}"
];
}
How can I make a function that returns the url replacing content inside brackets?
For example if I use this code:
$route->getUrl('view_article', 'first-article');
It should return: view/first-article

Answer 1

Then you should make a function that return your variable?
class Route {
function getUrl($find, $replace) {
$entry = isset($this->routes[$find]) ? $this->routes[$find]: false;
if($entry) {
return str_replace(sprintf('{%s}', $find), $replace, $entry);
} else {
return return false;
}
}
}
something like that.

Answer 2

function getUrl($key, $value){
$value = preg_replace('/[\[{\(].*[\]}\)]/U' , $value, $this->routes[$key]);
return $value;
}

Answer 3

A couple of solutions here:
getUrl below will accept the route name as the first parameter, then replace any placeholders with the subsequent variables. Not the best solution - you may have too many or too few variables. When using IDEs, there will be no parameter hinting.
class Route
{
protected $routes = [
"view_article" => "view/{articleUrl}",
"edit_article" => "edit/{articleId}",
"view_page" => "view/{articleId}/{pageName}"
];
public function getUrl() {
$arg_list = func_get_args();
$route = $this->routes[$arg_list[0]];
unset($arg_list[0]);
foreach($arg_list as $arg) {
$route = preg_replace('/{[^\}]+}/', $arg, $route, 1);
}
return $route;
}
}
$route = new Route();
var_dump($route->getUrl('view_page', '17', 'hello_world')); //'view/17/hello_world'
An alternative approach is to use an array of arguments and str_replace the key=>value pairs:
class Route
{
protected $routes = [
"view_article" => "view/{articleUrl}",
"edit_article" => "edit/{articleId}",
"view_page" => "view/{articleId}/{pageName}"
];
public function getUrl($routeName, $args) {
$route = $this->routes[$routeName];
foreach($args as $key => $value) {
$route = str_replace(sprintf('{%s}', $key), $value, $route);
}
return $route;
}
}
$route = new Route();
var_dump($route->getUrl('view_page', ['articleId' => 17, 'pageName' => 'hello_world'])); //'view/17/hello_world'
In both cases, be sure to include additional checks (route exists, all the variables have been replaced, etc).
