inserting data into columns and rows in php.

Hi! I'm trying make a page where you have a table with 3 columns. At different times the page might be empty or have hundreds of cells of informatin alla accessed from a dbase. here is the question: How can I tell php to insert a line of code into a page that starts another row in the table? basically I have something like this: <tr> <? //skipped the database connection part, this is the printing section, the problem printf("<td>column1</td>", $myrow["data"]); printf("<td>column2</td>", $myrow["data"]); printf("<td>column3</td>", $myrow["data"]); here 3 columns of data and after that php should insert </tr><tr> between the lines to start another row that is 3 columns long. printf("<td>column4</td>", $myrow["data"]); printf("<td>column5</td>", $myrow["data"]); printf("<td>column6</td>", $myrow["data"]); until there is no more data to be inserted into the table. I have trouble of creating the code needed so that php would insert </tr><tr> after every 3 rows of data from the database. Can anyone give a few pointer to the right direction. I hope I am making sense, if not, let me know and I'll try to clarify the problem a bit more. -- Maniac
