Do PHP developers need to know C?

Question

PHP

Hello!
Recently, at an interview for a junior php position, I was asked how php arrays are arranged under the hood, that is, a question about knowing hash tables in the C language.
Here are a few questions:
1. Does a php developer need to know c? If yes, at what level?
2. Does a junior php developer need to know c? If yes, at what level?
In case you think it is necessary - throw a couple of links to good literature on the topic.
Thank you.

Answer 1

Not necessary. Learn how design patterns and frameworks work better. Try to understand why and why this is done. And, those who require knowledge of C when applying for a juna php-shnik, went to hell.

Answer 2

"how php arrays are arranged under the hood, i.e. a question about knowledge of hash tables in the C language."
Knowing how arrays are arranged in php under the hood and knowing hash tables in C are completely different things.
The first is to superficially understand the structure, how they are stored, what the data structures for storing arrays consist of.
The second is a non-php task at all.

Answer 3

Now, in general, no one really needs to know purely C. Even controllers can already be written on a lot of things besides Sei.
Everything else, closer to everyday tasks, is sawn on "forks" - C #, C ++, etc.
In general, PHP has a similar syntax and I would say PHP is a very simplified C.

Answer 4

By the way, here is an article about the internal implementation of arrays in php https

needs.
I think that php june does not need to know C, apparently these are just pens of this employer.

Answer 5

My opinion
Does a php developer need C to solve everyday tasks at work - no
Is it possible to get a job (especially as a junior) without knowledge of C - yes, and very rarely there are questions for interviews in C
Will knowledge of C php be superfluous for a programmer - no.
Reasons:
- It's easier to switch to other languages
​​- You will understand programs more deeply, and this can help you solve specific problems and broaden your horizons in general.
