-- PLEASE UPGRADE TO v5.20 !**
|

|

> When fetching data in Associative mode (i.e. when `$ADODB_FETCH_MODE` is

Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
PHP's database access functions are not standardized. This creates a
|
||
|
|
need for a database class library to hide the differences between the
|
||
|
|
different databases (encapsulate the differences) so we can easily
|
||
|
|
switch databases.
|
||
|
|
|
||
|
|
The library currently supports MySQL, Interbase, Sybase, PostgreSQL, Oracle,
|
||
|
|
Microsoft SQL server, Foxpro ODBC, Access ODBC, Informix, DB2,
|
||
|
|
Sybase SQL Anywhere, generic ODBC and Microsoft's ADO.
|
||
|
|
|
||
|
|
We hope more people will contribute drivers to support other databases.
|
||
|
|
|
||
|
|
|
||
|
|
Installation
|
||
|
|
============
|
||
|
|
|
||
|
|
Unpack all the files into a directory accessible by your web server.
|
||
|
|
|
||
|
|
To test, try modifying some of the tutorial examples.
|
||
|
|
Make sure you customize the connection settings correctly.
|
||
|
|
|
||
|
|
You can debug using:
|
||
|
|
|
||
|
|
``` php
|
||
|
|
<?php
|
||
|
|
include('adodb/adodb.inc.php');
|
||
|
|
|
||
|
|
$db = ADONewConnection($driver); # eg. 'mysql' or 'oci8'
|
||
|
|
$db->debug = true;
|
||
|
|
$db->Connect($server, $user, $password, $database);
|
||
|
|
$rs = $db->Execute('select * from some_small_table');
|
||
|
|
print "<pre>";
|
||
|
|
print_r($rs->GetRows());
|
||
|
|
print "</pre>";
|
||
|
|
```
|
||
|
|
|
||
|
|
|

Documentation and Examples
|
||
|
|
==========================
|
||
|
|
|
||
|
|
Refer to the [ADOdb website](http://adodb.org/) for library documentation and examples. The documentation can also be [downloaded for offline viewing](https://sourceforge.net/projects/adodb/files/Documentation/).
|
||
|
|
|
||
|
|
- [Main documentation](http://adodb.org/dokuwiki/doku.php?id=v5:userguide:userguide_index): Query, update and insert records using a portable API.
|
||
|
|
- [Data dictionary](http://adodb.org/dokuwiki/doku.php?id=v5:dictionary:dictionary_index) describes how to create database tables and indexes in a portable manner.
|
||
|
|
- [Database performance monitoring](http://adodb.org/dokuwiki/doku.php?id=v5:performance:performance_index) allows you to perform health checks, tune and monitor your database.
|
||
|
|
- [Database-backed sessions](http://adodb.org/dokuwiki/doku.php?id=v5:session:session_index).
|
||
|
|
|
||
|
|
There is also a [tutorial](http://adodb.org/dokuwiki/doku.php?id=v5:userguide:mysql_tutorial) that contrasts ADOdb code with PHP native MySQL code.

Files
|
||
|
|
=====
|
||
|
|
|
||
|
|
- `adodb.inc.php` is the library's main file. You only need to include this file.
|
||
|
|
- `adodb-*.inc.php` are the database specific driver code.
|
||
|
|
- `adodb-session.php` is the PHP4 session handling code.
|
||
|
|
- `test.php` contains a list of test commands to exercise the class library.
|
||
|
|
- `testdatabases.inc.php` contains the list of databases to apply the tests on.
|
||
|
|
- `Benchmark.php` is a simple benchmark to test the throughput of a SELECT
|
||
|
|
statement for databases described in testdatabases.inc.php. The benchmark
|
||
|
|
tables are created in test.php.
