PHP Mysql to MySQLi conversion

[Sameer Sachdeva]

I have an existing code built in WAMP PHP 5x version, but unable to convert it to XAMPP PHP7 mysqli.

This piece of code is to populate a dropdown with a unique ID that will be used to submit to next page or post method. I want replacement syntax of mysql with mysqli for this loop. I am assigning unique ID to dropdown (Var_tech_id), which will be passed on to the next page / post method. How can I convert this mysql_result to mysqli_ equivalent code? Please suggest.

while ($array = mysql_fetch_array($result))
{
$var_tech_id = mysql_result($con, $result,$i, 0);
$var_tech_name = mysql_result($con, $result,$i, 1);
print "<OPTION value=$var_tech_id>$var_tech_name</OPTION>";
$i++;
}
Please take a note that I tried couple of things mentioned in other forums, but it did not work for me
