Hi Daniel,
Could you please tell us what version of PHP and OS you're using.
The following code fragment runs as expected on my PHP 5.3.2/Windows/XP/32bit:
<?php
header('Content-Type: text/plain');
class A
{
private function method_a( $argument )
{
echo('private method_a(\'' . $argument . '\') ...' . PHP_EOL );
}
public function __call( $method, $arguments )
{
if( method_exists( $this, $method ) && is_callable( array( $this, $method ) ) )
{
call_user_func_array( array( $this, $method ), $arguments );
}
else
{
echo('method \'' . $method . '\' either does not exist, or is not
callable ...' . PHP_EOL );
}
}
}
$a = new A();
$a->method_a('argument');
$a->method_b('argument');
?>
Results in:
private method_a('argument') called ...
method 'method_b' either does not exist, or is not callable ...
Perhaps if you provided some code we could spot the problem.
I would guess there's something fishy in your __call() method.
Best of luck,
Lawrance

__call() is receiving $method.
Do you alter $method in any way?
If not, calling call_user_func(array($this, $method), $args) will
simply call the non-existent function.
