  • 0

Under plain PHP 5.3, I have some code which uses MySQL to first deletes some old records, record a log, perform a few tiny operations and then adds new replacement records.

The delete command looks like this:

DELETE FROM `rtable` WHERE `UserName`='%s';

And the add commands looks like this:

INSERT INTO `table` (`UserName`,`Attribute`,`op`,`Value`) VALUES ('%s','%s','%s','%s');

Oddly though, the insert commands appear to not execute when running normally, however if I enable my debugger and step through one line at a time, it appears to work. Likewise, if I insert a sleep command of two seconds after the delete commands. It appears to work. I am therefor assuming that the insert commands are running -before- the delete commands and thus the delete commands are also erasing the new records.

How can I get PHP to wait for the delete operation to finish before continuing to the insert commands?

    That sounds really odd.
    Do you happen to have a replicated database cluster?
    Also, do you check the return value of the mysql_query or whatever command and print the error message (which of course is not recommended for scripts in production)?
