PHP MySQL to MySQLi

Congrats on this A+ article that helped me on migrating old php code do version 7 tested in ubuntu 16.04 server/LAMP;

one more function that helped me i found at another site and would like to share: mysql_result can be solved like this:

//php7
function mysqli_result($res,$row=0,$col=0){
$numrows = mysqli_num_rows($res);
if ($numrows && $row <= ($numrows-1) && $row >=0){
mysqli_data_seek($res,$row);
$resrow = (is_numeric($col)) ? mysqli_fetch_row($res) : mysqli_fetch_assoc($res);
if (isset($resrow[$col])){
return $resrow[$col];
}
}
return false;
}
