When it comes to databases or variables I want in several pages I make a separate page for them:

vars.php
[php]<?php

$var1 = "DB Name";
$var2 = "Hello";
$var3 = "39fmdi5l2ksd";
$var4 = "password";

?>[/php]

And then on each page I include the file:

page1.php
[php]<?php
include("vars.php");
...
echo $var1;
...
?>[/php]

page2.php
[php]<?php
include("vars.php");
...
echo $var4;
...
?>[/php]

Your other choice is to make variables GLOBAL.
Let me know if you still need help. :wink:

really i am trying global var from some time but it's dosen't work with me i don't know why !!!
anyway thankx for your help i will try that way hope it will work

and about global i will look for that link u put it thankx agein

Guest · **Points:**

In order for Global variables to work your server has to have them enabled. The easiest way to check is to run a phpinfo(); script:

phpinfo.php
[php]<?php
phpinfo();
?>[/php]

Then scroll down and see if you're PHP install has Globals turned on...

Many servers have them turned off because they can pose a threat to your site. A hacker can pass a page a variable that contains bad code. That is way I keep my variables in a page and just include them. :wink:
