Security is not a feature in programming languages. Security depends
on how the code is written.


Strictly speaking, you are correct.

However, I would argue that design decisions within the programming
language can help with how secure that code is by default.

I guess you are more talking about robustness than about security.

A language like Ada prevents various array index out of bounds
and wild pointers problems resulting in garbage data being
read, data being overwritten or crashes.

But PHP has none of those problems !

(the dynamically typed characteristics of PHP then creates
new types of potential programming bugs, but they are difficult
to compare with C)

ISTR that ADA is also strongly typed. It is not easy to store an int into a float. It can be done but you have to first explain to the compiler yes, I really, really, mean that. If a function takes two arguments, you had better supply exactly two. And so on.

It makes most of the most common screwups extremely difficult. You can still write bad code in Ada but you really have to work at it. I have seen exactly one shop that used it! I did a little little work for them
fourteen or fifteen years ago; installing some software
