RE: PHP, Zend, & mod_perl

[Laran Coates]

I haven't used php4/zend yet.

Are there any significant reasons to not use it yet, or is it basically
stable for most things?

Very good to hear your points on php3 vs. mod_perl though.  That helps a
lot.

Thanks.

Graeme,

I appreciate your thoughts and incentives, but you're going
off-topic here. there's a biased tone to your emails, so please
stop. a person asked for an objective comparison between 3
products, none of which is Roxen. i respectfully ask you to
stop the pedantic critizism and biased opinions. this is not
an apachec vs. roxen discussion. thanks.

Now, on to the subject...

I use both PHP and mod_perl heavily here are my observations:

PHP pros:
1) ease of use / small learning curve
2) very fast for small script
3) low resource footprint
4) easy to create / manipulate content with embedded code
5) MySQL support out of the box! (among many others)

mod_perl pros:
1) very fast for any sized scripts
2) vast library of options / extensions
3) DBI (need to say more?)
4) extends Apache functionality
5) small learning curve if you already know perl CGI's
   (no need to learn something new)
6) very fast

PHP cons:
1) slow with medium-large sized scripts
2) "make your own stuff" limited plugin options
3) datatype support is limited (ie., primitive arrays)
4) persistent transactions not supported (unless you get PHPLib)
   (well, you can always plug in mysql to do 'em, but sometimes
    this is not practical).

mod_perl cons:
1) huge memory footprint (get lots of ram)
2) screw up a module script and your server is toast.
3) if you dont know perl, you'll have a not-so-fun ride here.
   (although some people will argue perl is an easy language to
    learn, compared to php it's Haiku).

on PHP4 (Zend) ...

I've played with it and it does show great improvement. I guess
it's too early to comment, since it's still in the beta stage.
from what i've checked, it does solve all PHP-cons except #2,
but that one only time will fix.

i am sure i left a few pros/cons somewhere, please feel free
to aggregate to the list.
