dbase_replace_record — Replaces a record in a database

说明

dbase_replace_record ( resource $database , array $data , int $number ) : bool

Replaces the given record in the database with the given data.

参数

database

The database resource, returned by dbase_open() or dbase_create().

data

An indexed array of data. The number of items must be equal to the number of fields in the database, otherwise dbase_replace_record() will fail.

Note:

If you're using dbase_get_record() return value for this parameter, remember to reset the key named deleted.

number

An integer which spans from 1 to the number of records in the database (as returned by dbase_numrecords()).

返回值

成功时返回 true， 或者在失败时返回 false。

更新日志

版本	说明
dbase 7.0.0	database is now a resource instead of an int.

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 int element value (0 or 1) when retrieved via dbase_get_record() or dbase_get_record_with_names(). If they are written back, this results in the value becoming 0, so care has to be taken to properly adjust the values.
