In Symfony 4, you can retrieve a query string using the Request object, which is available through the controller's method arguments.


Here's an example:

1
2
3
4
5
6
7
use SymfonyComponentHttpFoundationRequest;

public function myControllerAction(Request $request)
{
    $queryString = $request->getQueryString();
    // do something with $queryString
}


In the example above, the $request object is passed as an argument to the controller's action method. The $request->getQueryString() method is then used to retrieve the query string from the request.


If you want to retrieve a specific query parameter from the query string, you can use the $request->query->get('parameter_name') method:

1
2
3
4
5
6
7
use SymfonyComponentHttpFoundationRequest;

public function myControllerAction(Request $request)
{
    $parameterValue = $request->query->get('parameter_name');
    // do something with $parameterValue
}


In this example, the $request->query->get('parameter_name') method is used to retrieve the value of a query parameter with the name 'parameter_name'. If the parameter is not present in the query string, the method will return null.

To get a query string in Symfony 4, you can make use of the Request object in your controller method. Here's an example:

1
2
3
4
5
6
7
use SymfonyComponentHttpFoundationRequest;

public function myControllerAction(Request $request)
{
    $queryString = $request->getQueryString();
    // do something with $queryString
}


In this example, the $request object is injected into the controller method as an argument. You can then use the $request->getQueryString() method to retrieve the query string from the request.


If you want to retrieve a specific query parameter from the query string, you can use the $request->query->get('parameter_name') method. Here's an example:

1
2

7
use SymfonyComponentHttpFoundationRequest;

public function myControllerAction(Request $request)
{
    $parameterValue = $request->query->get('parameter_name');
    // do something with $parameterValue
}


In this example, the $request->query->get('parameter_name') method is used to retrieve the value of a query parameter with the name 'parameter_name'. If the parameter is not present in the query string, the method will return null.
