Recursive PHP?

[Jørn Dahl-Stamnes]

Do PHP support recursive calling, like this:

function some_func ($some_arg)
{
$count = 0;
// some code
while (<some condition>)
{
if (<some condition>)
{
$count += some_func ($some_arg);
} else {
++$count;
}
}
return $count;
}

Did you not think to just try it out?

Yes, I did and it did not seem to work. I asked becasue maybe there was some
hack etc that I needed to do before it worked...

A newer version of my local version of the document. It say that it should
be possible, but this seems not to work on my server (PHP 4.3.9). Do I need
a newer version of PHP?

Ah well, you didn't say that! If you're not specific, you usually get a
condescending answer on Usenet.

What doesn't work? Did you get any error messages, etc.?

No, recursive functions have always worked.

For a more helpful reply, post more information.

After I saw the example in the document above, I tested it and found out
that it did work.
So after looking into my code again, I found a small error that resulted in
an incorrect return argument, which in the first place looked like it did
not work.

Thanks.
