Re: 'Pure' php vs 'mixed' (html + php)

I fell for this some time ago - but the trick is that 1. You don't do for ($i=0; $i<99999999999; $i++) { echo "Line $i<br>\n"; } in real life - you do stuff, call object methods, run queries, whatever, and in between those you have both html and php - and the remote machine waits for you to do all the "extra" stuff and _then_ waits for you to switch in and out of php for several times. I'm thinking about switching in and out of php in a "really-mixed" context - such as having blocks of html inside if() and while() blocks, stuff like that where you get to parse quite a number of php tags. 2. Your server doesn't only serve one client at a time - I'm surprised that you're starting with commercial sites and this piece of information isn't *always* present in your mind. However, as I said in my original mail, "there's an urban legend saying that [...] I don't know if that's true". So... I don't know if it actually slows things down or not.

I don't mind about this.. I'm starting with comercial pages now and before that I noted that any script you run at the server, you will only see this latency if the output is buffered or you have a ultra-fast machine with a super-powerfull navigator that can renderize the page before it's fully sent to the browser.. Try doing something like for ($i=0; $i<99999999999; $i++) { echo "Line $i<br>\n"; } Run the script in one machine and the browser at another.. you'll see that the client machine has the cpu burned much more then the server.. You can see this when you're trying to open that big-flat-forums all-in-one-page.. you'll get sometime 1. to receive that, 2. to renderize.. Note that you can only see the renderizing time if you're on a fast connection.. What I do take care is about excessive database searchs.. that can slow down the things since I'll probably will not have a reserved server..
