regex - php preg replace include slash(/)

one text

Solution:

Add / to the list of chars you want to keep

<?php
$jurnalName = "TL 110/90-12 K93-N02 AHM+";
$name = htmlspecialchars(htmlentities($jurnalName));
$name = preg_replace('/[^A-Za-z0-9|\-\s\+\/]/', '', $name);

var_dump($name);

(I also changed the space for \s and scaped the plus +, its optional here but I think its a good practice for characters that have spetial meaning inside regex
