recurcive call problem

[Anon]

hi there!

I have this function which prints an array recurcively...

function printToFlash($print_array){
if (is_array($print_array)) {
while(list($key, $val) = each($print_array)){
if(is_array($val)) {
printToFlash($val);
}else{
print $key."=".$val."&";
}
}
}

}

my question is:
how do I check to see if the loop is done

The outer 'if is_array' is unnecessary, unless you're trying
to protect the function against accidentally being called
with a non-array parameter.

But the function as written should work fine. You detect
the end of the loop within the 'while...each' loop: when
you get to the end of the array you simply don't make
another recursive call to printToFlash() so you're done!

When I test it this way:

  $inner = array( 'a','b','c');
  $data = array('one','two','three',$inner);

  printToFlash($data);

I get these results (printToFlash modified to say print "$key=$val<br>"😉:

&nbsp;&nbsp;0=one
&nbsp;&nbsp;1=two
&nbsp;&nbsp;2=three
&nbsp;&nbsp;0=a
&nbsp;&nbsp;1=b
&nbsp;&nbsp;2=c

yes, but if i wantet to do something in the same function just after the last print, how would i know that that "print" was the last and not just a part of the loop...?
