  Some tricks on PHP session

1. Session timeout problem There is a nuance we found with session timing out although the user is still active in the session.  The problem has to do with never modifying the session variable. The GC will clear the session data files based on their last modification time.  Thus if you never modify the session, you simply read from it, then the GC will eventually clean up. To prevent this you need to ensure that your session is modified within the GC delete time.  You can accomp...

  Tips for improving PHP efficiency

If a method in class can be declared as static, then make it static, this will be 4 times faster. 2. $row["id"] is 7 times faster than $row[id] 3. echo is faster than print, and you should use multiple parameters instead of string concatenation, i.e use comma(,) instead of dot(.) to concatenate string. For example echo $str1,$str...

  Why Apple Mac switches its CPU? The war between Intel and ARM

About three months ago, the new iPad Pro was released and it supports touch pad and mouse.

And if Mac and iPhone can share the same OS, it means the same app can run in all places. It is becoming clearer and clearer that Apple is planning to do this exact thing. Late...
