I am trying to pass a function as an argument to another function, and

function1(5, 100, function0($arg0, $arg1, $arg2));
<?
function func0($arg0, $arg1, $arg2) { /* do stuff */ }
function func1($arg1, $callback, $callbackArgs = /*order!*/array())
{
func3();
func4();
if (is_callable($callback)) {
$retval = call_user_func_array($callback, $callbackArgs);
}
}
func1(5, 'func0', array($arg0, $arg1, $arg2));
?>
the 'func0' in :
func1(5, 'func0', array($arg0, $arg1, $arg2));
could be something like:
array('ClassName', 'MethodName')
array($YourObject, 'MethodName')
In the above example, I am running function1(), which includes
function0 as an argument.
I am trying to pass "function0($arg0, $arg1, $arg2)" as an argument to
function1, which will then execute the passed function, including its
passed arguments.
I have had mild success by splitting "function0($arg0, $arg1, $arg2)"
into 2 parts of "function0" and "$arg0, $arg1, $arg2", and then
passing both parts as an argument, such as $arg5 & $arg6, and then
doing this:
function function1($arg3, $arg4, $arg5) {
$args_array = explode(", ",$arg6);
$arg5($args_array[0],$args_array[1],$args_array[2]);
}
However, this causes all of my arguments in the array to be evaluated
as strings and not resources, which they may be.
Also, I don't really like this method, and would prefer a much
"cleaner" way of doing things.
