Marek, you're a star ;-)

I *hate* having to ask someone to do my work, "mastering regular
expressions' in going on my christmas wish list! hehe... 

thanks again...

PS: Justin, got it covered. Thanks..

  $handle = fopen("page.php", "r");

$buffer .= fgets($handle, 4096);
  }
  fclose($handle);
file_get_contents() could be helpful here, too...

The value could be any number. I am trying to get that number.
If you have that exact string and you want to extract just the number, 
then a simple regex to delete all non-numeric characters should 
suffice.

I have this so far, i was hoping someone might tell me how to get that
number:

  $handle = fopen("page.php", "r");
  while (!feof($handle)) {
$buffer .= fgets($handle, 4096);
  }
  fclose($handle);
  $result = stristr($buffer, 'NAME="c"');
  print ("Result:".$result);
?>
Ok, so I don't see ' VALUE="16">' in here anywhere -- I think you need 
to be a lot more descriptive about the source content and what exactly 
you want to extract, and provide a few examples, so that we can cover 
all your bases.

Regular Expressions are _probably_ what you need, but you REALLY need 
to provide a decent description and multiple examples of what you want, 
otherwise we're just wasting time.

Im not very good at regex, is there an function that would help me?
(couldnt see one...)
thx...
preg_match('/value\s*=\s*"([0-9]+)"/i', $buffer, $result);
print ("Result:".$result[1]);

Not sure what your goal is here but the easiest (and most efficient) way
to get the first character of a string is :

  $string = 'abcdef';

  print $string{0}; // prints a
  print $string{3}; // prints d

So in your case, maybe the following craziness is what you're wanting :

  ${$string{0}} = 'crazy';

  print $a; // prints crazy

Philip Olson

$GLOBALS[substr($string, 0, 1)]
or :

$tmp = substr($string, 0, 1);
