Answer 1

You should really change the table structure and normalize your database. The best thing would be to create a new table to store the id_client and id_skill and remove the comma separated data from the 2nd table. However in your case you can try something as

select 
b.name_client, 
group_concat(a.name_skill) as skills 
from tableb b 
left join tablea a on find_in_set(a.id_skill,b.skill_client) > 0 
group by b.id_client ; 

Answer 2

Use explode(',', $myString);

$myArray = explode(',', $myString);

This get an array of Strings from a String.

if string is: "medical record, rontgen" then you get a array whit lenght two:

$myArray[0]= "medical record"

$myArray[1]= "rontgen"

Then your use json_encode($yourData) to convert vars u objects in json string.
