split help.. i think?

[magnus]

I have a variable, $threadinfo[foousers], which containts a list of users separated by spaces. (ie. $threadinfo[foousers] = "foo1 foo2 foo3").

I'm trying to add code to newreply.php that will check the current user against that list, and if a positive match is found it will return foo();

I've tried using the illegal username code, but I just can't seem to tweak it right.

Any help would be appreciated.

Wouldnt this be a job for good old Array??

You can only return something if you areb within a function and IIRC there are none in newreply.php anyway this should do what you want:

PHP Code:

if (in_array($bbuserinfo['username'], explode(' ', $threadinfo['foousers']))) {
    foo();
    exit;
}

Whats the Explode part about?? (Sorry just never seen that before)

[NTLDR]

Explodes all the values using ' ' (space) as the seperator into an array, for example:

PHP Code:

$test = 'a b c d';
$array = explode(' ', $test);


$array = array('a', 'b', 'c'); 


The top, essentially gives you the bottom result

Woops, forgot about this.. actually, I have it all working using:

PHP Code:

    if (!empty($threadinfo['foousers']))
    {
        $usernames = preg_split('/( )+/', trim(strtolower($threadinfo['foousers'])), -1, PREG_SPLIT_NO_EMPTY);
        foreach ($usernames AS $val)
        {
            if (strpos(strtolower($bbuserinfo['username']), strtolower($val)) !== false)
            {
                foo();
            }
        }
    } 


This is just modified code from vB's Illegalname check.
