Hi aa_prys (there is ALWAYS time for an introducing welcome line, especially if you are asking for help. It's a matter of politeness),

the output what i m getting after execution is [color=#4080FF]Notice: Use of undefined constant user_name - assumed 'user_name' in C:\xampp\htdocs\new1\view-users.php on line 32

Well, i "assume" that you are using an undefined constant on line 32 of your file C:\xampp\htdocs\new1\view-users.php.
Very very common (but you should get millions of hits on google if you try a search for "Use of undefined constant") you wanted to use a string, but have "forgotten" the quotes around it.

best wishes,
