RE: [PHP] how to get page count when uploading files
Oh, btw, I use PHP ftp function to upload the file, but there is no information in $_FILES to tell me the total page for Word or PDF file. Really appreciated your time and help! Thank you very much!

Each tld gets to do this however it wants. Mexico chose .com.mx and .gob.mx (the latter for government sites), for example, while the UK chose .co.uk and .me.uk (the latter for personal pages), etc. Since each one of these tlds is managed independently, it would be nearly impossible to construct a list of the possible second level domains for al the tlds. Sure, you might be able to get .mx and .uk info fairly easily, but what about .cc or .cx or .fj? And as soon as you do construct such a list, it will be out of date. If you are trying to verify a valid email address or a valid domain, there are better ways. -- Why can't you be in a good mood?

I am not sure if there exists any general list for what I originally looked for, but then again, then again, I am just realizing the specs I looked at in fact does not require it this specific after all. If there should be such a list somewhere I am still interested, but the link you gave me is good enough for what I needed it for. Again thank you!

[PHP] getting base domain and sub domains from url?
Hello all,
I am trying to extract base domains and sub domains from url's, and
expect there to exist something to do this already.
I used the parse_url($url) to get the host variable.
My thought is to use $domain_elements[]=array_reverse(explode('.',$url));
then simply check $domain_element[0] against some base of
international+country specific extensions, if they have sub-extensions
like "co.uk" then add
a third level to the domain list , and set this up as base domain. Any
levels beyond the registrable domain names would count as sub domains.
What I would like to know is if there are some lists of all these base
domains, or maybe some function already doing what I would like to do?
In advance, thanks!

We're appending certain fields to put together a total result. However, as mentioned, the amount of data collected is not anywhere near even 1MB, and in any event, all references to the result variable are unset (AFAIK) when I come up w/ the final 5.5MB number. > > It's entirely possible that PEAR::DB and/or DataObject are trying to > cache something to "help" you... > > You should be able to quickly hack a *BAD* page of code with minimal > error checking to do whatever queries PEAR::DB is doing for you. Yeah -- I was hoping to expand my understanding of PHP internals so I could avoid doing this, but based on more of your comments below I think I'm out of luck. I did note that DataObject was keeping a running cache of result sets (even ones that I was done with for some reason), so I added a destructor on my DataObject extending classes that cleans those up. That helps keep the running peak mem down, but is not part of the 5.5MB that I can't get rid of. > > > trigger_error(memory_get_usage()); > > $result = traverse_hierarchy(); > > At crucial points within the hierarchy, perhaps at nodes/leaves you > expect to be at specific milestones (halfway, 25%, 75%, ...) start > adding code that does crude things like: > > if ($node->name == 'This one node we think is halfway through') > trigger_error(memory_get_usage()); > > Log the numbers into a db with the node names and then later graph it > to see if the memory is getting chewed up in a straight line or if it > jumps at some point. > > If there's a big jump somewhere, you know where to look. > > If it's a straight line, then you can start doing the same thing line > by line to find where the RAM is going. Great idea -- I just completed a degree in computational physics, which included courses that involved dumping loads of data and graphing them using tools like gnuplot and OpenDx... you'd think I would have thought of this one myself (rolling my eyes). I _had_ thought of dumping the state at various, noted points throughout the process, but was hoping to avoid doing this kind of lengthy analysis. > > Did you close down the DB connection and kill the PEAR objects?... > > PHP's garbage collection has had... issues... in the past. All of my classes that extend DataObject inherit a common destructor that calls the DataObject::free() method, which, supposedly, frees result resources.

Outside a function, > it stays around. foreach, I think, correctly un-scopes the vars. This collection of statements is very illuminating. Part of my goal in posting this question was to find out more about how PHP internals work, esp. wrt GC. Sounds like there really isn't any hope of getting a solid set of rules that I can follow, and I have to allow for a little slop.

[PHP] how to get page count when uploading files
I really need help and after going through the help page, I don't know where I can post my question. When I upload a file (word or pdf), how can I know the page counts of that file immediately? Thank you, Jian
[PHP] Re: php and session issues continued...
How are you setting the location?
If the user starts at www.yoursite.com and you redirect to yoursite.com
after the first form then you'll lose the session since it's a different
domain.

Anyone recognise this issue. It is not IE-specific as it happens to me on

[PHP] Re: Please tell me I dont know regex
See http://uk.php.net/manual/en/function.eregi.php#57824
Basically you don't need to escape the dash, just place it somewhere
where it cannot be interpreted as indicating a range. It will then be
treated literally.
They do work the same using preg_match() which requires escaping.
