Something like this will work:
eregi("^id \{([a-z]*),([a-z]+),([a-z]+)\} \[(.+)\]$", $str, $regs);
$regs will be an array containing:
[0] => "id {name,title,nick} [http://www.php.net]";
[1] => "name"
[2] => "title"
[3] => "nick"
[4] => "http://www.php.net";
If course this isn't very foolproof or generic. For instance, this regex
assumes that you have exactly three comma-delimited substrings between
those curly braces and anything goes in the brackets. (It could be a URL,
but it could also be anything else.)
This is assuming there are three items between those curly braces, however.
To handle multiple configurations within the curly braces, you'd probably,
as the boundaries would cause items in the array to be overwritten during
matching. Something like this may work half-decent...
if (eregi("(id) \{(.*)\} \[(.*)\]$", $str, $regs))
{
$p[0] = $regs[1];
$p[1] = explode(",", $regs[2]);
$p[2] = $regs[3];
}
$p should now look like the following:
[0] => "id"
[1][0] => "name"
[1][1] => "title"
[1][2] => "nick" )
[2] => "http://www.php.net";
That should do it. Of course, the regex again isn't foolproof, as you could
have crazy stuff for a URL, and it doesn't bother to check if there's
anything after a comma in the curly braces, but will handle any number of
items between the braces, and it's enough to get you started.
