范例
Example #1 Updating a record in the database
<?php // open in read-write mode $db = dbase_open('/tmp/test.dbf', 2); if ($db) { // gets the old row $row = dbase_get_record_with_names($db, 1); // remove the 'deleted' entry unset($row['deleted']); // Update the date field with the current timestamp $row['date'] = date('Ymd'); // convert the row to an indexed array $row = array_values($row); // Replace the record dbase_replace_record($db, $row, 1); dbase_close($db); } ?>
注释
Note:Boolean fields result in an integer element value(0or1)when retrieved via dbase_get_record() or dbase_get_record_with_names(). If they are written back, this results in the value becoming0, so care has to be taken to properly adjust the values.
