This function is equivalent to
<?
isset($array[$key]);
?>
The only difference seems to be in the warning messages:
if you use an incorrect $key (= not a string or a number), isset would give you a "Illegal
offset type" warning (in fact it is the passed expression that would generate it) and
array_key_exists would say
"array_key_exists(): The first argument should be either a string or an integer"...
