splitting a string based on a pattern

Hi,
What I want is to split a string based on the following pattern

starts with '@{'
any number of characters can follow but when it finds a closing curly
bracket it should end. So the following expressions should match

@{x}
@{x_1_23}
@{y|hello|good|}

So lets say

$s =  '@{x}+@{y12}=@{ans}fwf{sdfe@{d}wer32r3';


so this should be split in

+
=
fwf{sdfe
wer32r3

I've tried the following code but it doesnt work

<?php

$s = '@{x}+@{y}=@{ans}fwf{sdfe@{d}wer32r3';

$regex = '(@{).+}';  /* doesn't work */

$arr = split($regex,$s);

foreach ( $arr as $a)
echo '<br>' . $a;

?>

Also is there a way to store the patterns that have matched?  @{x},  @{y12}
etc

Thanks

You are looking for:
preg_match_all

Thanks! However, what would the regular expression be in this case?

Code

<?php

$table = "@{x}+@{y12}=@{ans}fwf{sdfe@{d}wer32r3";

preg_match_all("|@{(.*)}|U",$table,$rows);

//Loop through the table
foreach ($rows[0] as $row){

//Returned all the contents
echo $row."<br>\n";

}
?>

With thanks to John Dunlop from comp.lang.php without whose help I would not
know this

<?php

$s =  '@{x}+@{y12}=@{ans}fwf{sdfe@{d}wer32r3';


print_r(preg_split('/@\\{[^}]+\\}/',$s));
