範例
示例 #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);
}
?>
註釋
注意:
Boolean fields result in an int 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.
