Hi,
Why is func_num_args not working on closures?
Example code (tested on PHP 5.3.8):
<?php
class Test
{
public function testClosure($oClosure)
{
echo '<pre>';
print_r(func_num_args($oClosure));
echo '<pre>';
}
}
$c = new Test();
$c->testClosure(function($arg1, $arg2){
});
That returns 1 (the num of args in which function the closure is
(testClosure), but not the number of args from the closure itself.
Now Reflection can be used to get the number of args but that is overkill!
Also when you would do print_r(func_get_args($oClosure)); you do get
"something" back including the arguments but no way (that i know) to use
them!
Just something that i wonder...
I would have expected num args to return the args of the function you
provide it..
Kind regards,
Mark
