[PHP] domain.org/?page=pageName method
A general thing to do while coding a site is to include header.php at the top of the file (and footer.php at the end of file). Another method is to put these header and footer files together in index.php and including the desired page between them. We get the desired page from the query string: domain.org/?page=pageName $page = $_GET['pagename']; include $page.'.php'; Is there any important difference between these two methods? What can you say about the advanteges or disadvanteges of one to the other? Assume that including undesired pages is prohibited. I mean don't write about page=../../secretpage Thanks... __ Do you Yahoo!? Yahoo!

Re: [PHP] algorythm question
ok, now it's clear why i must use '|' instead of '+'. i still couldn't get what happens with bits but you don't have to explain more. i know that it's about bitwise operators, and how they handle numbers. no! ok! i just got it! thank you again. --- bob parker <[EMAIL PROTECTED]> wrote: > Couple of points: > You really do need to use the '!' operator to > combine the categories not '+' > eg if your user entered 2 twice you would get > $userLevels = 2 + 2; // wrong we just made our admin > a writer > but > $userLevels = 2 | 2; // ok is still admin because > $userLevels is still 2 > > These operators, | and & are called bit wise > operators to see how they > work look at the binary representations of the > numbers > say $userlevel = 15 then in binary > $userlevel is > $result = & 0001;// $result is 0001 binary or > decimal 1 > $result = & 0010;// $result is 0010 binary or > decimal 2 > $result = & 0100;// $result is 0101 binary or > decimal 4 > $result = & 1000;// $result is 1000 binary or > decimal 8 > the '&' operator only returns the bit or bits which > are both 1 in the > same column. > > The or operator returns the bits which are 1 in > ether column so > 2 | 2 which is 0010 | 0010 still returns 0010 which > is 2 > Hope this helps > bob __ Do you Yahoo!?

Re: [PHP] algorythm question
oh my god. here is an example.
$userLevels = array(
1 => 'Member',
2 => 'Admin',
4 => 'Writer',
8 => 'Expert');
$cat = 15;
for ($mask=1; $mask <= 64; $mask *= 2) {
if ( $mask & $cat ) {
print "Yes $mask is in $cat\n";
}
}
here i didn't have to 'or' the IDs but it works fine
and i didn't really understand how it works?
what does it mean "if 2 & 15, 2 can be found in
15"???!!! is that a miracle;)
thank you bob...

[PHP] algorythm question
consider there are categories and these have IDs like below: 1, 2, 4, 8, 16, 32, 64... if some data belongs to more than 1 category for exemple 4 and 32, its category ID will be 36, the sum of cat. IDs. i guess this is used widely in programming. so, how can i resolve the original IDs. i mean what kind of script can tell me what+what1+what2...whatN = 79? __ Do you Yahoo!?

[PHP] PHP and OOP
i want to build a site in fully OO style but that will significantly slow down execution time and i'm about to make a u turn to procedural PHP programming on my project. that article is responsible of changing my decision: http://zend.com/zend/art/mistake1.php#Heading13 besides it will be more modular, reusable, e.t.c... PHP is not a OO language but supports them so should classes bu used ONLY where needed, NOT where procedural programming can do fine? a forum topic for this subject is also at: http://www.zend.com/phorum/read.php?num=3&id=18612&loc=0&thread=18612 __ Do You Yahoo!?

Re: [PHP] include through HTTP
file.php does more than one jobs depending on
HTTP_GET_VARS. for example if "..?mod=show" or it is
empty it shows things, elseif "..?mod=update" it
updates... so i must send a variable to the included
file but i can't do it in the file that includes it.
The file that includes file.php is a template file
which holds the design of the site and each page is
included in to that template.
My English is not very good so if you can't see a
reason not to do it your way i will try to write a
more clear explanation.
Thank you!
Oh! that's an important point:
on index.php(the template file) it decides which file
to include with a switch.
//querystring: /index.php?page=a_page
switch $page
case "a_page":
$inc = "http://$myhost/a_page.php";;
case "another_page":
$inc =
"http://$myhost/a_page.php?mod=something";;
include($inc);

[PHP] include through HTTP
What i want to do is :
include("http://localhost/folder/file.php?foo=bar";);
but it doesn't work. As you may guess it looks for a
file called "file.php?foo=bar". "url_fopen" is set to
"on" in my php.ini file as told in the PHP manual.
I work on win98+apache+php4.1.1(or something like that
but at least 4.1...)
Do you know what's the problem?
