I need help with a PHP function im writing. My code:
function get_config() {
$db = dbServer::getInstance();
$mysqli = $db->getConnection();
$sql_query = 'SELECT * FROM server_config';
$result = $mysqli->query($sql_query);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$serverStatus = $row['server_status'];
$serverTitle = $row['server_title'];
}
}
}
Now, If I'd want to call the function and only echo let's say, $serverTitle, how should I do that? I.e:
get_config($serverStatus)?
Best regards

hello, i am guessing that the the query returns only 1 row in that case it's vary easy. if it's more than 1 row then you would have to treat the result as an array else you are overwriting the values in each iteration.
Return the value if it is only one OR create an array and return that array from the function.I think it should be only one value.
