strangely, I had a similar sounding problem using:

if (ord($word{0}) >= 127) {
}

under PHP 5 the other day.

Description:
------------
Apache process hangs out when calling ord() with reproducible
arguments.



Reproduce code:
---------------
function isalpha( $char )
{
  return( (ord($char) >= ord("a") and ord($char) <= ord("z")) ||
  (ord($char) >= ord("A") and ord($char) <= ord("Z"))  );
}

echo is_alpha('|') ;

... PHP hangs ...


Expected result:
----------------
false

Actual result:
--------------
nothing ( php hangs calling ord() )


------------------------------------------------------------------------
