how to set array element/sort array in php

Question

Hello All i want to sort the array in the way that

ASC order of user id

there is array like $user

i want to sort on the base

id $user['role'] =1;

then that element will set at the top of the array

Answer 1

Look in the PHP manual at asort, sort, and ksort. I'm not exactly sure what you're asking, but one of them is bound to do what you need.

Answer 2

Does that information come from a database? In that case, doing something like ORDER BY role DESC, user_id would be better than having PHP sort it for you.

Answer 3

If your array example $user['role'] = 1 means that 1 is the user id you want to use sort($user); however if role is going to be numeric you would want asort($user); instead as sort will overwrite numeric keys. As @Rob above said you may want to use ksort but only if you are making the array $user[user_id] = role.

Hope this helps

Thanx All For Replying on my question

i got the solution here it is

function compare($a,$b) {return strcmp($a["role"]['ID'],$b["role"]['ID']);} usort($a,compare);
