Perfect way for generating random string...

Looks practical enough to me.
You didn’t say uniquely random 😂

@IllSlapU yep, the whole codebase is a garbage, mostly we can't even understand the previous devs' logic - but sometimes we find some even worse snippets, like this.

@irene Same here, I don't get it.

As long as the "rand" functions works well enough it should produce a new random string from given characters every time

@irene, @Froot well yes, at least it works but it's not too pretty and a bit slow for a solution - problem is, there are too many slow and not pretty code in this project, making it unstable and incredibly slow - and a big pain to fix anything

@irene, @Froot also, as now I see, it could simply fail if called.
strlen returns the string's length, rand's max is inclusive in PHP, so it could reference to an undefined index

It depends on what you want to use it for.

@irene I'm on it. :)

snake_case and camelCase at once

@harrizsb I didn't see it, but it doesn't surprise me xD

Im not a php pro but isnt there a "str_random" function in the php standard library?

I don't see the issue. It works doesn't it?

@FetzenNET not in PHP nativity., unless you use OpenSSL’s random_bytes

Possibly, some frameworks have a function to do this which would probably work in a similar way.

@DuckyMcDuckFace nope, it also fails as I said above ;)
