example, test efficiency

Code to copy the code as follows

　　

Speed can be spelled with PHP (though still not as fast as he does),

Another way to use it is

Code to copy the code as follows

S=join (Array ("1", "2", "3",....., "9999"))

The speed is still much faster than "1" & "2" & "3" & .....& "9999"
