The plugins version number can be obtained using
MYSQLND_UH_VERSION
or
MYSQLND_UH_VERSION_ID
.
MYSQLND_UH_VERSION
is the string representation of the numerical version number
MYSQLND_UH_VERSION_ID
, which is an integer such as 10000.
Developers can calculate the version number as follows.
Version (part) | Example |
---|---|
Major*10000 | 1*10000 = 10000 |
Minor*100 | 0*100 = 0 |
Patch | 0 = 0 |
MYSQLND_UH_VERSION_ID | 10000 |
