Xampp - can't read PHP, MySQLi at the browser - Fatal error with PEAR

Question

I don't know what exactly happens because I have a page ready to handle-up a login system but it's only programmed in html and css yet. Why?

Because when I try to program something in php like this to start making the login system works;

Document called Connections

<?php
$con = mysqli_connect("localhost", "root", "84df86a16c3bf8fb94dd3824b9144604", "thunderorbit");
?>

My register document with all the html

<?php
require '/ThunderOrbit/Loginscreen/Connections.php';
?>

all the html (I won't paste it or it will ocupy the whole page xD but it works before I write nothing in PHP or using mySQLi with PHP)

The error log;

Warning: require(/ThunderOrbit/Loginscreen/Connections.php): failed to open stream: No such file or directory in C:\xampp\htdocs\ThunderOrbit\Loginscreen\Loginscreen-Index.php on line 4

Fatal error: require(): Failed opening required '/ThunderOrbit/Loginscreen/Connections.php' (include_path='C:\xampp\php\PEAR') in C:\xampp\htdocs\ThunderOrbit\Loginscreen\Loginscreen-Index.php on line 4

Attention to (include_path='C:\xampp\php\PEAR') please I don't understand what to do, help!!

Answer 1

The solution was here:

Change

<?php

require '/ThunderOrbit/Loginscreen/Loginscreen-Connections/Loginscreen-Connections.php';

?>

To

<?php

require '/Loginscreen-Connections/Loginscreen-Connections.php';

?>

Because PHP isn't the same as HTML or CSS, regarding links.

Answer 2

If the file you are requiring is in the same directory just name the file.

require('Connections.php');

Answer 3

Make sure PHP has access to that file.

Answer 4

Maybe PHP Windows and Linux compatibility path, change \ to PATH_SEPARATOR or DIRECTORY_SEPARATOR constants. Reference about PATH_SEPARATOR
