        Why is this an issue?

        When the line immediately after a conditional has neither curly braces nor indentation, the intent of the code is unclear and perhaps not what is executed. Additionally, such code is confusing to maintainers.

        if ($x > 0)  // Noncompliant
        doTheThing();
        doTheOtherThing(); // Was the intent to call this function unconditionally?
        

        It becomes even more confusing and bug-prone if lines get commented out.

        if ($x > 0)  // Noncompliant
        //    doTheThing();
        doTheOtherThing(); // Was the intent to call this function conditionally?
        

        Indentation alone or together with curly braces makes the intent clear.

        if ($x > 0)
            doTheThing();
        doTheOtherThing(); // Clear intent to call this function unconditionally
        
        // or
        
        if ($x > 0) {
            doTheThing();
        }
        doTheOtherThing(); // Clear intent to call this function unconditionally
        

        This rule raises an issue if the line controlled by a conditional has the same indentation as the conditional and is not enclosed in curly braces.
