If you're in a language that supports it, please don't use if (false) use if ($disallowAllUsers = false && $whateverTheRealConditionIs)

Never seen this, what language or buildsystem is this?

That specific language is PHP, but the tip is applicable in any language that supports inline assignment.

if (true === $wantToCauseErrorsForFun) {
    badOldFunction();
}

The assignment syntax is too close to comparison, which is what is more typical in that position. I would recommend

const bool _isFeatureEnabled = false;
if (_isFeatureEnabled &amp;&amp; ...)

if not a proper feature flag (or just remove the code).

It seems much worse to use a setter in an if statement.

Think of it as inline attribution/documentation.
