## Why is this an issue?

There is no good reason to create a new object to not do anything with it. Most of the time, this is due to a missing piece of code and so could lead to an unexpected behavior in production.

If it was done on purpose because the constructor has side-effects, then that side-effect code should be moved into a separate method and called directly.

### Noncompliant code example

    if ($x < 0) {
      new foo;  // Noncompliant
    }

### Compliant solution

    $var = NULL;
    if ($x < 0) {
      $var = new foo;
    }
