[RESOLVED] Pre-decrementing operators (Zend Cert)

[crmpicco]

Hi again,

Personally, I can't see how any of the answers below are suitable - but i'm obviously wrong. Can anyone advise?

Q: What is the output of the following?

<?php
function 1dotEach($n)
{
  if ($n > 0)
  {
    1dotEach(--$n);
    echo ".";
  }else 
  {
    return $n;
  }
}
1dotEach(4);
?>

Grazie,
Picco

Function names cannot begin with a number - parse error.
