Making function for php condition statement -

-

i'm new php, i'm making online cart website in php admin panels, i've 3 type of users 1: admin (all roles) 2: sellers (who sell items) 3: customers/buyers (who buy items)

          function user_access($user){         $_session['access'] == '$user';         return $user;     }       if(user_access('admin')){         echo "you logged in admin";     } else { echo "undefine access"; }

but outpul same :( how can make functions type of conditions, wordpress.

sorry bad english,

this: 

function user_access($user){     $_session['access'] == '$user';     return $user; }

should just:

function user_access($user){     return $_session['access'] == $user; }

so, need remove quotes around $user, , return result of comparison, not $user variable.
