  5. //Determine whether this file exists
  6. if(file_exists($file_path)){
  7. if($fp=fopen($file_path,"a ")){
  8. //Read file
  9. $conn=fread($fp,filesize($file_path)); > //Replace string
  10. $conn=
  11. str_replace("rn","

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started.
