recursive function/foreach

[kikidonc]

Hello,
here stands my troubles:

function display($a,$b)
{
global $source;
/
[...]
/
$last = sizeof($a) - 1;
foreach($a as $key => $value)
{
if($key == $last)
{display($source[$key],'yes');}
else
{display($source[$key],'no');}
}
}

I was expecting the 'display()' function to be called before it has gone out of the foreach statement but it doesn't actually...
does anybody have an idea that would lead me further?

Thanks a lot,
Fred.

The only reason why this would not call itself is if the $a is empty.

Note to state the obvious: the IF is highly illegal, a function must always have an escape. But I guess you did that IF ELSE thing for testing right?

$a is never empty.
The function is running well but not in the order I'd like it to be :-).

I don't get the second part of your mail: why is the 'if' statement illegal?

the function can escape, once $a is not an array anymore(it's in the [...] part). Then I don't do the foreach statement and the "cascade" of called functions exits one after the other.

"the function can escape, once $a is not an array anymore(it's in the [...] part). "

Ah well there's your problem then,
somewhere in the block that you did not post is a bug that makes $a into a non-array, which causes the loop to stop.
