Obtaining the mysqlnd plugin API
The mysqlnd plugin API is simply part of the MySQL
Native Driver PHP extension, ext/mysqlnd.
Development started on the mysqlnd plugin API in
December 2009. It is developed as part of the PHP source repository,
and as such is available to the public either via Git, or through
source snapshot downloads.
Plugin developers can determine the mysqlnd
version through accessing MYSQLND_VERSION, which
is a string of the format mysqlnd 5.0.7-dev - 091210 -
$Revision: 300535
, or through
MYSQLND_VERSION_ID, which is an integer such as
50007. Developers can calculate the version number as follows:
| Version (part) | Example |
|---|---|
| Major*10000 | 5*10000 = 50000 |
| Minor*100 | 0*100 = 0 |
| Patch | 7 = 7 |
| MYSQLND_VERSION_ID | 50007 |
During development, developers should refer to the
mysqlnd version number for compatibility and
version tests, as several iterations of mysqlnd
could occur during the lifetime of a PHP development branch with a
single PHP version number.
