hi mate,

i am just start coding with my PHP, i have to know about populate (fetch) content from database anyway so you no need to worry about this section

today when i am trying to implement my new web task that my use can select any post category and i have to done with this task but there is one thing getting wrong

first of all, here is sample of my URL to get list of post based on category that my user clicked:

so this URL would fetch all content (post title, post author, post content, cat label, etc) but when i enter non exist cat id it will show show error like invalid argument supplied for foreach.

what should i do when my user want to get non exists cat_id without any php error instead show a 404 page error
