Some of what PHP considers to be a warning would be an error elsewhere.

Loose equality in comparisons is an absolutely moronic feature and
gives you code that appears to work right until certain input is
provided to it.

It's even more moronic that it's the default behaviour and you have
to work to get the strict equality you would see in other programming
languages.

Would this by any chance be the same people who just want to continue
throwing bits of code into an editor until what they are building
appears to start working ?

A beefed up version of code like this is included into the top of
