It can still go down, for sure.
Using mysql_ping to see if it's still up at any given moment, though,
is probably a bad idea.
It can STILL go down between mysql_ping() and whatever (real) work you
want to do with mysql.
So you STILL need the same level of error-checking on your actual real
work statements.
So the ping is mostly just a waste of bandwidth.
There might be a specific use-case of 'mysql_ping', such as some kind
of "heartbeat" script that sends you an email if mysql has been down
for more than X seconds.
But you almost for sure don't want to just scatter mysql_ping
throghout normal code.
