The description block gives a fairly precise explanation for how version numbers are compared: after a couple character replacements, numeric parts are compared as numbers and non-numeric parts (eg, "alpha" and "rc") are compared according to a hierarchy. >hmm, you can strtolower before compare, I'd prefer this to be a doc problem.. The operator parameter says "This parameter is case-sensitive, so values should be lowercase". Maybe move that somewhere more obvious, like the description or a note? ------------------------------------------------------------------------ [2012-07-17 14:53:13] laruence@php.net hmm, you can strtolower before compare, I'd prefer this to be a doc problem.. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
