[serbanghita]

[ioempire]

Thanks
Now I get this error:

[16-Jan-2024 09:49:03 UTC] PHP Fatal error: Uncaught Error: Class "Detection\Cache\Cache" not found in /home/friudeni/public_html/Mobile-Detect/src/MobileDetect.php:1032
Stack trace:

thrown in /home/friudeni/public_html/Mobile-Detect/src/MobileDetect.php on line 1032

In line 30 I have:
$detect = new MobileDetect();

I Use php version 8.0

@ioempire it's because you're not using composer autoload like in this example https://github.com/serbanghita/Mobile-Detect/blob/4.8.x/scripts/example.php

you will have to manually include all dependent files from https://github.com/serbanghita/Mobile-Detect/tree/4.8.x/src

[ioempire]

But what is this line:
require_once DIR . '/../vendor/autoload.php';
vendor and autoload.php is not in the Mobile-Detect directory

[ioempire]

Now my code look like this:
$mobil=0;

include($_SERVER['DOCUMENT_ROOT']."/Mobile-Detect/src/Cache/CacheException.php");
include($_SERVER['DOCUMENT_ROOT']."/Mobile-Detect/src/Cache/Cache.php");
include($_SERVER['DOCUMENT_ROOT']."/Mobile-Detect/src/Cache/CacheItem.php");
include($_SERVER['DOCUMENT_ROOT']."/Mobile-Detect/src/Exception/MobileDetectException.php");
require($_SERVER['DOCUMENT_ROOT']."/Mobile-Detect/src/MobileDetect.php");

use Detection\MobileDetect;
$detect = new MobileDetect();
$detect->setUserAgent();
if( $detect->isMobile() && !$detect->isTablet() )
$mobil =1;

And I get this error:
[16-Jan-2024 10:56:06 UTC] PHP Fatal error: Uncaught Error: Interface "Psr\SimpleCache\CacheInterface" not found in /home/friudeni/public_html/Mobile-Detect/src/Cache/Cache.php:7

@ioempire 4.8 is meant to be used with composer with composer require mobiledetect/mobiledetectlib, in the above case you're missing a dependency.

I'm sorry for misguiding you, I didn't realised that 4.8 is fully dependent on composer autoload (which is kinda like what modern PHP env looks like).

Just start from scratch use the code from 2.8 branch
https://github.com/serbanghita/Mobile-Detect/tree/2.8.x then you don't need to include anything, see https://github.com/serbanghita/Mobile-Detect/blob/2.8.x/examples/test.php - it's the same detection, but the code is compatible with classic way of manually including the class.

[serbanghita]

In summary:

4.8 - use composer and example https://github.com/serbanghita/Mobile-Detect/blob/4.8.x/scripts/example.php
2.8.x - you can use classic include - https://github.com/serbanghita/Mobile-Detect/blob/2.8.x/examples/test.php
