Greetings,
I had some problems with broser caching behaviors and php name space
collision. I do lot of googling and try to figure what happened and I failed
to figure. So I need help,
Here Details
1-) Browser Cache Beahviors
You know the back button problem. I search the net and found some header
modifications to fix this problems.
Like this
ini_set('session.cache_limiter', 'private');
that's not a header, it's a php.ini setting. Just not-picking though,
don't have an answer to this as I've personally never had problems with
caching (then again, I also rarely use sessions)
And this will lead the some caching issues. Time to time browser may forgot or
misbehave with javascripts.
Is there any suggestion for this.
When visitor hit back button and previous page has retun data from post
variables.
1-) Re posting without any message
2-) No content cache
2-) The another problem was developing aproach.
Currently I'm working on large CMS thingy. My project be able to include php
files anytime anywhere and unlimited amount.
So time to time variable names will collide and it was so hard to detect.
Prefix your variables if they're important. You probably couldn't care
less if variables like $i, $j, $k, etc. are overwritten, but variables
holding important content for you should be "secured" by either storing
them in a specific place you know to be safe, or by prefixing them. eg:
$myApp_foo, $myAll_bar, etc. If anyone makes an include for you, they
will be very unlikely to use such names there too. The other way, which
I personally prefer is to put everything important and non-local (ie.
isn't confined to that one file it's run in) in special purpose arrays:
$SETTINGS[various names], $SELF[names], $MYAPP_SAFE[names]
Is there any suggestion to avoid these kind of collisions.
Thanks
Sancar
