Call a PHP variable to another PHP file

Question

I'm trying to pass a variable from a dbh.inc.php to index.php using include_once, But it gives me an error in $con at index.php that it is not defined

dbh.inc.php:

<?php

$dbServername = "localhost";
$dbUsername = "root";
$dbPassword = "";
$dbName = "loginsystem";

$con = mysqli_connect($dbServername, $dbUsername, $dbPassword, $dbName);

indux.php:

<?php
include_once 'includes/dbh.inc.php';
?>
<!DOCTYPE html>
<html lang="">
<head>
    <title></title>
</head>
<body>
<?php
$sql = 'SELECT * FROM users;';
$result = mysqli_query($con, $sql);
$resultCheck = mysqli_num_rows($result);

if($resultCheck > 0)
{
    while ($row = mysqli_fetch_assoc($result))
    {
        echo $row['user_uid'] . "<br>";
    }
}
?>
</body>
</html>

Maybe the path for the include is wrong because there is nothing wrong with your code — FarrisFahad

If you put them in the same file it works?! If so then you are probably calling the file with the wrong path... if it doesn't it means that $con wasn't created because you didn't succeed in loggin in to you db. — Shlomtzion

Usually you can access variables from one file to another by including file like:

vars.php

<?php

$color = 'green';
$fruit = 'apple';

?>

test.php

<?php

echo "A $color $fruit"; // A

include 'vars.php';

echo "A $color $fruit"; // A green apple

?>

First of all check it by turning on the error reporting for that particular file and you will get error if the included path was not correct.

you can add it as follow:

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Thanks
