you are concatenating an array (which will be cast to a string)
to a string - this won't do what you want.
also putting '$row[user_id]' in double quotes is pointless,
remember that if you don't put it in double quotes then you
have to quote the array 'key' like so (or suffer an E_NOTICE):

<? echo $row['user_id']; ?>

so to build up an (indexed) array (as opposed to associative):

<?php

$uidToAdmin = array();
while ($row = mysql_fetch_array($result)) {
// put user ID's into an array;
$uidToAdmin[] = $row['user_id'];
}

// DEBUG:
// I'll assume you will run this via your browser
// therefore a <pre> tag is used to make the output
// readable
echo '<pre>';
var_dump( $uidToAdmin );
echo '</pre>';

?>

I would suggest you take (another?) look at the
documentation on arrays, php arrays are really very very
cool - knowing how to use them properly is a
powerful weapon in your php arsenal. :-)

have fun
