PHP session_start（）问题？

Question

can I include my session_start() in my header include or should I past session_start() in every pages? Is there any pros or cons in pasting the session_start() in the header include?

Answer 1

session_start() should probably be one of the first lines. you have to start the session before any data is output. if you're using includes to simulate a template system then stick it in the page controller.
