Hi,

One option is to pass the variable over in the url. Your link in index.php that directs to detail.php would look similar to this:
a href="detail.php?var=$var"

Then on detail.php; use GET to grab the variable.

$var=$_GET['var'];

If you're going to send anything funky in the variable such as special characters use $var=urlencode($var); first to get it browser-friendly.

Then $var=urldecode($var); after your GET statement on detail.php to restore it back to its original form.

I can see TWO options.

Using session. $_SESSION['varname'] = Jonny
These varaibles will follow a user, and remain until he CLOSE his browser down.

2.
As mentioned using THE URL to put in variables in link
and get them with $_GET['varname'].

<?php // index.php

$name = "Jonny";
$age = "15";
$city = "London";

// link
echo '<a href="details.php'
.'?var1=' .$name
.'&var2=' .$age
.'&var3=' .$city
. '">goto details</a>';

?>

<?php // details.php

$name = $_GET[ 'var1' ];
$age = $_GET[ 'var2' ];
$city = $_GET[ 'var3' ];

?>
Hello world<br>
<?php
echo "$name is $age years old, and comes from $city.";

?>

I'm not totally clear from your message, but are you getting these variables from a form?

in order to pass variables through pages without using includes?

i would use sessions.

for a session on any page:

<?php
session_start();
$_SESSION['var1'] = 'num1';
$_SESSION['var2'] = 'num2';
?>

and as long as you start the session, they will stay there. start with session_start();
