php - Best practices for URL with space and special characters -

-

i'm modifying small web application. web application allow users enter / specify category themselves. noticed in database, there's plenty of category contain spaces , special characters, example cakes & cupcakes.

on front-end, database shows user defined categories in form of url links , user can click on them further see what's in category.

the front-end category links encoded using rawurlencode function , looks this.

./show.php?category=<?php echo rawurlencode($e['category']); ?>

and on back-end, function get url , decode before it's being sent database querying.

$category = rawurldecode(htmlspecialchars_decode($category));

it works fine seems 'last-minute' , 'unsophisticated'.

as such i'm wondering, best practice in php url special characters , spaces?

thank in advance.

i prefer use "slug" method. "slugify" strings , use slug in url.

you'll need add column database slug, can represent user input fields in url , make them readable. "function-to-slugify-strings-in-php" slug looked "function slugify strings in php".
