mysql - php does not import variables from another file -


i'm working on cloud system login/register system , mysql, problem php not imports variables i'm including.

here config file:

<?php // connection details $servername = "localhost"; $username = "root"; $password = "password"; $dbname = "database";  ?>

and code include config file:

require("/classes/config.class.php");

when i'm trying echo variables defined in config gives error:

notice: undefined variable: servername in c:\xampp\htdocs\index.php on line 2

i'm using xampp on local computer has php version 5.5.30.

edit: first lines of php, comment

<?php  // include classes require("/classes/user.class.php");  require("/classes/password.class.php");  // include configuration require("/classes/config.class.php");  echo $servername; echo $username; echo $password; echo $dbname;

i write answer because can't type carriage returns in comments.

your code in index.php (as comment above):

<?php // include classes require("/classes/user.class.php"); require("/classes/password.class.php"); // include configuration require("/classes/config.class.php"); echo $servername; (...)

double slashes // comment sign, meaning following text in same line ignored.

i suggest (also better code clarity) edit in way:

<?php     // include classes      require("/classes/user.class.php");     require("/classes/password.class.php");     // include configuration      require("/classes/config.class.php");      echo $servername;     (...)

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
