Add a "case default" clause to this "switch" statement.
Open

        switch ($event['type']) {
Severity: Critical
Found in src/Http/Controllers/Services/Traits/UserHandler.php by sonar-php

The requirement for a final case default clause is defensive programming. The clause should either take appropriate action, or contain a suitable comment as to why no action is taken. Even when the switch covers all current values of an enum, a default case should still be used because there is no guarantee that the enum won't be extended.

Noncompliant Code Example

switch ($param) {  //missing default clause
  case 0:
    do_something();
    break;
  case 1:
    do_something_else();
    break;
}

switch ($param) {
  default: // default clause should be the last one
    error();
    break;
  case 0:
    do_something();
    break;
  case 1:
    do_something_else();
    break;
}

Compliant Solution

switch ($param) {
  case 0:
    do_something();
    break;
  case 1:
    do_something_else();
    break;
  default:
    error();
    break;
}

Remove this unused "$userEvents" private field.
Open

    private $userEvents = [
Severity: Major
Found in src/Http/Controllers/Services/Traits/UserHandler.php by sonar-php

If a private field is declared but not used in the program, it can be considered dead code and should therefore be removed. This will improve maintainability because developers will not wonder what the variable is used for.

Noncompliant Code Example

class MyClass {
  private $foo = 4;                       //foo is unused

  public function compute($a) {
    return $a * 4;
  }
}

Compliant Solution

class MyClass {

  public function compute($a) {
    return $a * 4;
  }
}
