Hi

We have an application developed with PHP4 should it run quite happily against PHP5?

Thanks in advance

Hard to say without detailed info, though chances are it will work fine.... why not just test it on a dev machine and find out?

thanks for that :)

I have tried it on the system and I don't get past the index.php page LOL :)

however it works fine within phpED debug environment so I must have set something up wrong.

thanks for your help anyway.

cheers

The differences between PHP4 and PHP5 are summarised at http://www.zend.com/php5/zend-engine2.php - if these don't apply then the chances are good that it's some sort of difference in configuration between the two servers - if the application assumes the server is configured in a certain way when it isn't.... Compare the results of phpinfo() on the two servers as an aid to comparison.
