It seems like $ixr_client is not always an object, but can also be of type boolean. Maybe add an additional type check?

If a variable is not always an object, we recommend to add an additional type check to ensure your method call is safe:

function someFunction(A $objectMaybe = null)
{
    if ($objectMaybe instanceof A) {
        $objectMaybe->doSomething();
    }

Documentation introduced by
$user_id is of type integer, but the function expects a boolean.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

Both the $myVar assignment in line 1 and the $higher assignment in line 2 are dead. The first because $myVar is never used and the second because $higher is always overwritten for every possible time line.
