> I used PHP for five years professionally, I consider myself as well positioned as many to have an informed opinion about PHP weaknesses and strengths.

Yeah, that doesn't mean anything. In fact, to be frank, when I read that, I fill in the underlying context:

"I used PHP for fives years professionally, and the code was horrible. Granted, it was code I wrote because PHP let me write code that way..."

or

"I used PHP for fives years professionally, almost a decade ago..."

> I remember we had even built a code checker that was forbiding the use of many php functions and syntax, and had a set of wrappers around basic functionalities like string functions or date functions.

Yeah, that didn't do much to change my mind.
