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.
The following table shows PHP versions and the corresponding
mysqlnd version contained within.
Table 7.8 The bundled mysqlnd version per PHP release
| PHP Version | MySQL Native Driver version |
|---|---|
| 5.3.0 | 5.0.5 |
| 5.3.1 | 5.0.5 |
| 5.3.2 | 5.0.7 |
| 5.3.3 | 5.0.7 |
| 5.3.4 | 5.0.7 |
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:
Table 7.9 MYSQLND_VERSION_ID calculation table
| 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.
