14 NOTE: This driver requires the Advantage PHP client libraries, which
15  can be downloaded for free via:
16  http://devzone.advantagedatabase.com/dz/content.aspx?key=20
17 
18 DELPHI FOR PHP USERS:
19  The following steps can be taken to utilize this driver from the
20  CodeGear Delphi for PHP product:
21  1 - See note above, download and install the Advantage PHP client.
22  2 - Copy the following files to the Delphi for PHP\X.X\php\ext directory:
23  ace32.dll
24  axcws32.dll
25  adsloc32.dll
26  php_advantage.dll (rename the existing php_advantage.dll.5.x.x file)
27  3 - Add the following line to the Delphi for PHP\X.X\php\php.ini.template file:
28  extension=php_advantage.dll
29  4 - To use: enter "ads" as the DriverName on a connection component, and set
30  a Host property similar to "DataDirectory=c:\". See the Advantage PHP
31  help file topic for ads_connect for details on connection path options
32  and formatting.
33  5 - (optional) - Modify the Delphi for PHP\X.X\vcl\packages\database.packages.php
34  file and add ads to the list of strings returned when registering the
35  Database object's DriverName property.
