the DOM extension is php5 only! it replaces DOMXML. again the SOAP extension (very nice it is too) is php5 only.

I am I found DOM to be easier to use than SimpleXML (but that was due to the fact that it was impossible to inspect the structure/content of SimpleXML objects using var_dump(), print_r(), etc - I believe this has since been fixed satisfactorily) > sure there are many other packages that are only supported on PHP 5 and are > quite useful. indeed! ... http://php.net/manual/en/ref.datetime.php http://php.net/manual/en/ref.stream.php (exists in php4.3+ but improved/extended in php5) http://php.net/manual/en/migration5.functions.php http://php.net/manual/en/ref.mysqli.php (for connecting to mysql4.1+) > > I presume that is a good enough reason :). Forget about OOP and exceptions. while I agree that exceptions don't really offer anything that couldn't be done with 'std' error handling - it does offer an alternative which some people might prefer ... having the choice is nice in and of itself. I wouldn't recommend forgetting OOP - the OO functionality in php5 is an improvement in terms of proper ctors, PPP, 'overloading', and that objects are always by reference (and not by value as in php4) - allround I would suggest php5's OO model is a big step forward even though it entails that you will have to be a bit more strict with regard to how you write you OO code. http://php.net/manual/en/language.oop5.php obviously choosing OO over procedural style, or vice versa is a question of taste (I use both depending on the needs, time of month, my mood :-) > > Regards > Nauman Akbar > Concise Solutions > > -----Original Message----- > From: Niels [mailto:[EMAIL PROTECTED] > Sent: Tuesday, December 19, 2006 11:05 PM > To: php-general@lists.php.net > Subject: [PHP] Are PHP5 features worth it? > > Hi list, > > I'm writing a PHP program and I've got a number of concerns.
