Answer 1

Check your php.ini, you should have use session cookies turned on. This means session_start must be used before *any* output is sent to the browser (in your case the html tags).



Also, you are using the @ operator in front of session_start, this means to suppress any errors, if you remove that, php might tell you an error on why the sessions are not working.



HTH

Answer 2

Well , the reason of this is output is being generated before session_start();.

This is not the thing that we have to put it before tag , but we should not generate any output before session_start function.



So simple if you want to use it then always start your file with
// rest code after that.



I hope this will solve your problem

Answer 3

Headers like "session_start()" should be placed before I think.
