This section provides information about constants defined in the PHPlot class. As these are PHP constants, they are accessed without a leading $ and cannot be expanded inside string values.
The version
constant contains the PHPlot code version as
a string, for example "5.4.0"
.
(This was added in PHPlot-5.4.0.)
The version_id
constant contains the PHPlot code version as
an integer, using the conventional formula 10000*major_version +
100*minor_version + patch_version.
This was added in PHPlot-6.0.0 (with value 60000) to make it
possible for the test suite to check for a minimum version.
This version of the manual was produced for the
