random1 Posted February 20, 2008 Share Posted February 20, 2008 Hey all, Is there any way of having backwards compatabilty between PHP5 and version 4? Maybe some function code? I have created a web app that uses PHP5 but I want it to be able to be run on PHP4 too. Quote Link to comment Share on other sites More sharing options...
PFMaBiSmAd Posted February 20, 2008 Share Posted February 20, 2008 The end of life of php4 has already gone past. Except for security patches, no new versions of php4 will be released. Everyone and every hosting company should have already upgraded or should have a short term schedule in place for upgrading to the latest version of php5. Don't waste time making your code php4 compatible. If you want, make sure it is php6 ready (some depreciated and insecure features have been eliminated http://derickrethans.nl/files/meeting-notes.html#cleanup-of-functionality ) Quote Link to comment Share on other sites More sharing options...
