Question

Originally, this simple array and a foreach statement works perfect, but I need to change from a php array to getting the information out of the database:

$serversArray = array(
    "domainname1.com",
    "domainname2.com:port",
    "domainname3.org",
    "000.000.000.000:port");

foreach($serversArray as $server)

.

ID    IP                Port
1     domainname1.com   
2     domainname2.com   12345
3     domainname3.org   
4     000.000.000.000   54321

What I need to figure out is how to get the IP and Port columns formatted into ip:port (with the colon in between), and then make the foreach statement recognize each one so it can process it with some other script, just like how it works already with the array. (I have also tried using sprintf in the foreach, but that broke the page.)

Answer 1

Do you want build the $serversArray from a DB query?

$serversArray = array();
$sql     = "SELECT ip, port FROM my_table";
$result = mysql_query($sql);
while ($row  = mysql_fetch_array($result))
{
    // if have port include it after : otherwise just include ip
    $serversArray[] = $row['port'] ? "{$row['ip']}:{$row['port']}" : $row['ip'];
}

Old fashion sql queries are just to show the procedure to build the array. At the present time we should use MySQL Functions (PDO_MYSQL)
