I am considering to move frome Microsoft languages to PHP (just for web dev) which has quite an interesting syntax, a perlish look (but a wider programmer base) and it allows me to reuse the web without reinventing it. I have some concerns too. I would be more than happy to gather some wisdom from stackoverflow community, (challenge to my opinions warmly welcome). Here are my doubts.
Efficiency. Cgi are slow, what I am supposed to use? Fastcgi? Or what else?
Efficiency + stability. Is PHP on windows really stable and a good choice in terms of performances?
Database. I use very often MSSQL (I regret, i like it). Could I widely and efficiently interface PHP with MSSQL (using smartly stored pro, for example).
XSLT + XML performance. I work quite a lot with XML and XSLT and I really find the MS xml parser a great software component. Are parser used in PHP fast, reliable and efficient (I am interested mainly in DOM, not SAX)?
Objects. Is the PHP object programming model valid end efficient?
6 Regex. How efficient is PHP processing regexp?
Many thanks for your advices.
