    Database Abstraction with PEAR - DB_Result::fetchRow


    (Page 7 of 7 )

    mixed fetchRow ([integer $fetchmode [, integer $rownum]])

    OK, we have seen everything we need to do except actually get the data. This function will grab a single row from a result set. It will return either a row of data, NULL if there are no more rows, or an error object. The neat thing about this fetchRow function is that you specify the row number you want it to grab. This comes in handy when you are dealing with a DBMS that doesn't support LIMIT or a similar function.

    There are three fetch modes you can specify with this function:DB_FETCHMODE_ORDERED - this is the default fetch mode and will return an array with numerical keys.DB_FETCHMODE_ASSOC - this mode returns an array with column names as the keys.DB_FETCHMODE_OBJECT - this mode will return an object with column names as the properties.

    Typical usage for this function:

    <?php
    $row 
    $result->fetchrow(DB_FETCHMODE_ASSOC);
    ?>
