How To Query Tables and Loop through the Returning Rows
How To Query Tables and Loop through the Returning Rows? - MySQL FAQs - Managing Tables and Running Queries with PHP Scripts
✍: FYIcenter.com
The best way to query tables and loop through the returning rows is to run the SELECT statement with 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"; $res = mysql_query($sql, $con); while ($row = mysql_fetch_assoc($res)) { print($row['id'].",".$row['url'].",".$row['time']."\n"); } mysql_free_result($res); mysql_close($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:
101, dev.fyicenter.com, 2006-07-01 22:29:02 102, dba.fyicenter.com, 2006-07-01 22:29:02 1101, dev.fyicenter.com, 2006-07-01 22:29:02 1102, dba.fyicenter.com, 2006-07-01 22:29:02
Don't forget to call mysql_free_result($res). It is important to free up result set objects as soon as you are done with them.
