mysql pconnect , when it close connection
In genral ,

for mysql_connect have mysql_close ,

but mysql_pconnect does not have any close function ,

i saw in all threads and tutorial , they are saying that for mysql pconnect , 

    First, when connecting, the function would first try to find a (persistent)
    link that's already open with the same host, username and password.
    If one is found, an identifier for it will be returned instead of 
    opening a new connection. 
  
    FRO ---> php.net manual


b default there is no close function for mysql_pconnect , then in tutorial,

why they are saying like 

> the function would first try to find a
> (persistent)
>     link that's already open with the same host 

As per this line :-- may be in some occasion,  mysql_pconnect connection will close ,

Then when this connection will close ,in which situation connection goes close mode ,

or is there any  time out for cloase connection or time limit ,

i guess this quesiton little but childish ,
