Description:
------------
The manual page for array_key_exists does not state in any form that array_key_exists DOES NOT WORK on multidimensional arrays. 

http://php.net/array_key_exists

Test script:
---------------
$array = ("horse","tree","card");
$array['guard']['dog'] = "wOOF";
if (array_key_exists("dog",$array)){
    print "found!";
}
else {
    print "Dog not found!";
}

// Never finds array key dog. Only searches first level of array.

Well, PHP doesn't have multidimensional arrays; it's just that an
array value can be an array. However, that doesn't mean that a key
that exists in such an inner array belongs to the outer array.
Therefore the documentation is not in error, in my opinion.

While that may be so, I am asking that the documentation clarifies this point.

Okay, I guess a respective note can't hurt, and there are other
parts of the manual mentioning multidimensional arrays, so:

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
