How To Query Tables and Loop through the Returning Rows? - PHP Script Tips - Working with MySQL Database

The best way to query tables and loop through the returning rows is to run the SELECT statement with the catch the mysql_query() function, catch the returning object as a result set, and loop through the result with the mysql_fetch_assoc() function in a while loop as shown in the following sample PHP script:

<?php
  include "mysql_connection.php";

  $sql = "SELECT id, url, time FROM fyi_links";
  $rs = mysql_query($sql, $con);
  while ($row = mysql_fetch_assoc($rs)) {
    print($row['id'].", ".$row['url'].", ".$row['time']."\n");
  }
  mysql_free_result($rs);

  mysql_close($con); 
?>

Using mysql_fetch_assoc() is better than other fetch functions, because it allows you to access field values by field names. If you run this script, you will see all rows from the fyi_links table are printed on the screen:
