dbase_replace_record()

(PHP 5 < 5.3.0, dbase 5, dbase 7)

Replaces a record in a database

说明

dbase_replace_record(resource $dbase_identifier,array $record,int $record_number): bool

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

参数

$dbase_identifier

The database link identifier, returned by dbase_open() or dbase_create().

$record

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 nameddeleted.

$record_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。

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.
