Since mysql connect has been deprecated  connect and query instead with mysqli    mysqli   new mysqli  hostname   username   password   database name     sqlSelect  SELECT your fieldname FROM your table    result    mysqli - gt  query   sqlSelect     And then  if you have more than one option list with the same values on the same page  put the values in an array   while   row   mysqli fetch array  result          rows      row      And then you can loop the array multiple times on the same page   foreach   rows as  row        print   lt option value       row  your fieldname        gt      row  your fieldname       lt  option gt

No need to do this    while   row   mysqli fetch array  result          rows      row      You can directly do this   while   row   mysqli fetch array  result             echo   lt option value       row  value        gt      row  value       lt  option gt

You will need to make sure that if you re using a test environment like WAMP set your username as root  Here is an example which connects to a MySQL database  issues your query  and outputs  lt option gt  tags for a  lt select gt  box from each row in the table    lt  php  mysql connect  hostname    username    password    mysql select db  database-name      sql    SELECT PcID FROM PC    result   mysql query  sql    echo   lt select name  PcID  gt    while   row   mysql fetch array  result         echo   lt option value       row  PcID        gt      row  PcID       lt  option gt      echo   lt  select gt       gt
