dbase_replace_recordReplaces 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.

注意:

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

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
  
$row dbase_get_record_with_names($db1);
  
  
// 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($db$row1);
  
dbase_close($db);
}

?>

注释

注意:

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.

Make sure you opened the database for WRITE!
dbase_open( "yourfile.dbf", 2)
