Dmitry, this script should fail for all of those:
<?php
function doTitle($a = NULL, $b = NULL) {
print "doTitle: $a, $b\n";
}
function doHead() {
doTitle(func_num_args());
doTitle(func_get_arg(0));
doTitle(func_get_args());
}
doHead("1", "2");

Manual says:
"Note: Because this function depends on the current scope to determine
parameter details, it cannot be used as a function parameter. If you
must pass this value, assign the results to a variable, and pass the
variable."

Well, that's true then. But I'm not sure how important this bug is :)

Hi Derrick,
I don't consider to be bug, that it cannot be used as function
argument.
However I consider to be bug, that it CAN be used if you use it only
once.
This works:
doTitle(func_get_arg(0));
This works also:
doTitle(func_get_arg(1));
So it should not work at all, to be consistent.
Ondrej.

Description:
------------
func_get_arg() can be used as argument to function only once.
Reproduce code:
---------------
<?php
function doTitle($a = NULL, $b = NULL) {
print "doTitle: $a, $b\n";
}
function doHead() {
doTitle(func_get_arg(0));
doTitle(func_get_arg(1));
doTitle(func_get_arg(0), "3");
doTitle(func_get_arg(0), func_get_arg(1));
}
doHead("1", "2");
?>
Expected result:
----------------
doTitle: 1,
doTitle: 2,
doTitle: 1, 3
doTitle: 1, 2
Actual result:
--------------
doTitle: 1,
doTitle: 2,
doTitle: 1, 3
Fatal error: func_get_arg(): Can't be used as a function parameter in
/tmp/func_get_arg.php on line 11
