There is an absolutely phenomenal static analyser for PHP called enhanced inspections EA (free version and commercial very) that will flag == when === should be more appropriate (among many other things). For people not using Intellij (or wanting a tool that can be used as part of commit/deploy setup there is phan which is well executed). I've mocked PHP for a long time (been using it for various day jobs for over a decade) but they've made massive strides in the last 2-3 years to the extent where used properly it's approach 'not a bad' language status.
