Documentation suggestion

I have noticed that the online documentation lists the supported php versions for the particular feature you are currently reviewing. It also lists all the functions to the left. Both of these documentation features are good, but there can be a problem with users with a particular version of PHP in mind. Take for example somebody looking at image functions. The function "imagecopyresampled" works only with php >= 4.06 while "getimagesize" works with both php 3,4. If somebody were looking for php 3 specific functions, they would have a hell of a time looking at the documentation because the list of functions to the left would keep showing php 3,4, 5 functions when they are only interested in php 3. I think there ought to be a mechanism put in place to remove references to documentation which is incompatible with the version of php being looked at; php 3 users should be able to look up php 3 documentation. Php 4 users should be able to see everything that works for php 4. When php 5 comes out, have php 5 specific documentation available. I do like having the info on what versions of php support a particular feature. For instance the listing of "getimagesize" as being compatible with php 3 and 4 is useful if I were to regress to php 3 (for some strange reason). I would think that you could have a drop down menu next to the text field for users searching the documentation which would have version numbers available. For the documentation page, you could simply add links for each version. In both cases, you could also have an "all versions" option which would display the documentation for php without filtering features to match a specific version number. I think it would make an already great language easier to work with if the documentation would be viewable in a version specific context. -Jason Rogers Human Factors Research and Technology Division Human Information Processing Research Branch NASA Ames Research Center http://human-factors.arc.nasa.gov/ihh http://pbagroup.arc.nasa.gov/
