How include in php works?

How include in php works?

I have file a.php and data folder in one folder. In data folder, I create
two files: b.php and c.php. Content of each file
a.php
<?php
$a = 1;
include('data/b.php');
?>
b.php
<?php
include('data/c.php');
?>
c.php
<?php
echo $a;
?>
When I run file a.php, result is 1. But I change content of file b.php to
include('c.php'); the result of file a.php is also 1, I think it it show
an error because file a.php and file c.php is not in one folder. Thank
you.

Setting a cookie based on query string for split testing

Setting a cookie based on query string for split testing

If a query string is detected, I want to update/set a cookie so a
particular dir is used for that browser session or until the query string
is explicitly set again. Visitor is not to see the dir, but instead will
just see http://mydomain.com/.
This is what I have so far but it doesn't work as expected. Pretty sure
I'm writing the logic wrong, but not sure where.
RewriteCond %{QUERY_STRING} splittest=(A|B)
RewriteRule splittest=(A|B) [CO=splittest:$1:%{HTTP_HOST}:0:/,L]
RewriteCond %{QUERY_STRING} splittest=A [OR]
RewriteCond %{HTTP_COOKIE} splittest=A
# Split test A
RewriteRule ^(.*)$ A/$1 [L]
# Split test B
RewriteRule ^(.*)$ B/$1 [L]

Questions about STL containers in C++

Questions about STL containers in C++

How often do std::multimap and std::unordered_multimap shuffle entries
around? I'm asking because my code passes around references to distinguish
between entries with the same hash, and I want to know when to run the
reference redirection function on them.
What happens if I do this:
std::multimap Table; //Tyype specification stuff left out
//Code that pus in two entries with the same key, call that key foo
int bar = Table[foo];
Is the result different if it's an unordered_multimap instead?
Back to passing references around to distinguish entries with the same
hash. Is there a safer way to do that?

URL rewrite not working in CodeIgniter hosted with dreamhost

URL rewrite not working in CodeIgniter hosted with dreamhost

So I've gone through dozens of forum posts and websites between dreamhost,
codeingiter etc. I have a file directory set up in codeigniter hosted on
dreamhost as follows: mysite.com > application|system|user_guide|.htaccess
the live site i can access is mysite.com/index.php/site/WhatIwantToKeep
my .htaccess file reads:
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?/$1 [L]
Currently if i go to mysite.com/site/WhatIwantToKeep it can't find it. If
i place any IfModule tags or options lines, it gives a server 500 error.
Ideally this code would rewrite it so that my urls would be reading:
mysite.com/WhatIwantToKeep
Thanks!

PHP - MySQL - How to check if value updated or not

PHP - MySQL - How to check if value updated or not

I have a php code to update / change value of already existing record like;
$con = mysql_connect("server","username","password");
if (!$con){
die('Could not connect: ' . mysql_error());
}
mysql_select_db("database", $con);
$query = mysql_query("UPDATE table SET field1='$newvalue1',
field2='$newvalue2' WHERE key = '$key'") or exit(mysql_error());
echo "true";
I want to echo "true" if data is updated and echo "false" if there is some
syntax error or if record don't exist or something else, where record
value remain unchanged. How can I do this?
Note: I know mysqli* and I prefer it over mysql*, but here for traditional
mysql*
Thanks in advance...:)
