20416,Install plugins version checking not correct,Workshopshed,,"The version checking does not seem to be treating the numbers in the same way a person would, when I view the ""details"" the screen says:

Newer Version (1.63) Installed
FYI
Version: 1.7

Surely 1.7 is newer than 1.63.

Looking in the code I see that install_plugin_install_status is the function that manages this which is in wp-admin\includes\plugin-install.php

That in turn uses ""version_compare"" to check the versions. Experimenting with that function which is a php function it would seem that:


{{{
version_compare('1.7','1.63', '<')    = true
version_compare('1.7','1.6', '<')     = false
version_compare('1.70','1.60', '<')   = false
version_compare('1.70','1.63', '<')   = false
}}}


So a work around for this is to ensure that people use a standarised numbering convention. This behaviour has been there since 3.0.0.
