Hmm.... your pattern looks incorrect, since you're really only matching the
string "{}".  What you're saying is "Split all the segments of the subject
string that are separated by '{}'".

Also, preg_split returns an array, so you can't expect echo() to output it
correctly.  Use print_r for outputting the contents of arrays (or any variable,
for that matter.)

I've posted this function a thousand times, because I use it for EVERY script I
write, even the toy scripts I write to answer questions in this forum.

function printr($var, $desc = '')
{
  echo "<PRE>";
  if($desc != '')
  {
     echo "$desc:\n";
  }
  print_r($var);
  echo "</PRE>\n";
}


Back to your script.  I think you'd be better off with preg_match or
preg_match_all, since you seem to want items that are contained within a
pattern, not separated by one.

$pattern = "/{([^}]+)}+/";

This pattern searches for one or more instances of {...} in a string.  Breaking
down the pattern, you see that I look for an open curly brace, then one or more
characters that are _not_ the closing curly brace, then the closing curly
brace.  I parenthesize the text found within the curly brace.


Here's a short test script and it's output:


---------------------------------------------
<?php
function printr($var, $desc = '')
{
  echo "<PRE>";
  if($desc != '')
  {
     echo "$desc:\n";
  }
  print_r($var);
  echo "</PRE>\n";
}


$pattern = "/{([^}]+)}/";

$games = '{gta3}{madden 2003}{vice city}';

if(preg_match_all($pattern, $games, $fgames))
{
    printr($pattern, '$pattern is');
    printr($fgames, '$fgames is');
}

?>
---------------------------------------------

Output:
---------------------------------------------
$pattern is:
/{([^}]+)}/

$fgames is:
Array
(
    [0] => Array
        (
            [0] => {gta3}
            [1] => {madden 2003}
            [2] => {vice city}
        )

    [1] => Array
        (
            [0] => gta3
            [1] => madden 2003
            [2] => vice city
        )

)
---------------------------------------------



Take care,
