Hi,
There is no equivalent of “strict mode” in PHP. Do not confuse it with “strict_types”, which
has nothing in common except the word “strict” in its name..
Strict mode in JS was introduced to disable design mistakes that couldn’t be removed due to very
strong (almost inflexible) BC contraints. In PHP, we have deprecations followed by removals in next
major version.
(And some people, including me, will argue: while JS strict mode disables design mistakes, PHP
strict_types mode *is* a design mistake.)
