Before 5.3 call_uer_func_array() could convert copied values in the array to
references, something like
<?php
$v = 42;
$a = array($v);
func f(&$param) { $param = 0; }
call_user_func_array('f', $a);
echo $v; // prints 0
?>
"worked", while obviously being wrong. This was fixed.
Anyways, both call_user_func() and call_user_func_array() have their place, one
for doing dynamic stuff, secondly for compatibility, no need to get rid of
those. Adding syntactical sugar for calling things is a different question, but
a key element of the PHP language design is to have verbosity, so that even
people who don't know all constructs have a chance to search for it. We're
getting rid of this slowly (i.e. due to things like $a = [ ] ) but we houldn't
loose this idea completely.
