Does PHP have an equivalent to Python's all()

Question

Python has a nice all() (doc) method that returns true if all elements in an iterable are true, which is equivalent to:

def all(iterable):
    for element in iterable:
        if not element:
            return False
    return True

Is there a similarly nice way to do this in PHP?

Answer 1

There’s no such function, but you can achieve the same effect with:

count(array_keys($array, 'yes')) == count($array)

Answer 2

Closest to it may be array_filter, if no true element are found it will return empty array that evaluates to false.

On the second thought it’s more like pythons any(). To emulate all() you will need if(array_filter($array) == $array) or even if(array_filter($array) == $array && $array) to exclude empty array.

Answer 3

If all your values are boolean, this would be a simpler approach:

in_array(true,$array)
