May be we should have something like

So array_filter?
I'll use it or like for deleting, but the point of this thread is
"intuitive function for deleting element(s)"
array_delete($array, $value|callable)
would be nicer for users, perhaps.
You are basically asking to alias array_filter with "array_delete".
That is
a very slippery slope. I think array_filter is very a very obvious choice
to remove something from an array. The "filter" function/method is common
in functional languages (and functional frameworks like Underscore).
These are things developers just need to learn as part of development.
Really, this is entire thread should be on stack overflow, not internals.
You seem a little arrogant. Arguably, a lot of array functions are
unnecessary. But PHP is not supposed to be an extremely minimal
language. Convenience functions are a good thing.
We have array_pad for instance: completely unnecessary, you can do it
manually with other array functions. Array_fill_keys and array_fill,
too. array_flip is also unnecessary. Heck, who needs sorting, you can do
that manually too.
array_delete would be a more convenient, and more readable way to remove
a value from an array. Yes, you can already remove array items, that's
not the point. The point is this way is simpler and more convenient.
So you just want a convenient and readable way and you realise yourself,
that it is really simple to implement. So: Why don't you just implement
it yourself?
function array_delete($array, $value) {
// Your code here
}
What I don't understand is, why should every function goes directly into
the core, if you can achieve exactly the same without core changes?

Also, as someone else mentioned, PHP's universal collection datatype is
a great thing. It is an associative array, it is a list, it is a tuple,
it is a set, it can be used in many ways, it's incredibly versatile.
Adding array_delete would allow you to use it like a set more easily.
Just my 2½¢ :)
