Well.. You can have both 4 and 5 installed on both Apache 1 and 2 if you want to.. Which Apache version to use doesn't really matter.. I use 1.3, and I have PHP 2, 3, 4 and 5 installed. PHP 4 as Apache module and the rest as CGI binaries.. Instructions in manual.. You can't force PHP5 to only accept PHP4 syntax, and that would be pointless since you could anyway use PHP4 in that case. You could have one folder using PHP5 and one using PHP4 if you want to, as long as you install one of them (or both) as CGI.. You can only have one of them as Apache module at a time.. Which one to have as module is the one you will likely use the most.. Doesn't matter all that much though.. Hope that helps.. -- // DvDmanDT MSN: dvdmandt¤hotmail.com Mail: dvdmandt¤telia.com "Bobo Wieland" <bobo.wieland@xxxxxxx> skrev i meddelandet news:000f01c4ad1f$d871e1f0$5cea1e0a@xxxxxxxxxxxxxxxxxx Hi all! I'm about to reinstall PHP/MySQL/Apache (+ MySQL Front) on my WinXP machine... It's been a while since I last installed this package and there have been some version changes... Should I go for the old Apache or Apache 2? And most important; can I have a dual install of php4 and php5 or is it possible to force php5 scripts to run in php4 compability mode? My webserver is just local and I use a webhotell for everything I do. They do not have php5 installed. And probably won't have it for quite a while. I donät want to make scripts that wont work bcause of their older version of php. At the same time I want to migrate to php5 so that I can learn it... How should I do? _bobo wieland -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
