Question on fopen, fwrite..

[mr666]

i have a php form (edit_info.php only for logged-in members) when submitted,

1.update mysql database (table:user_info)
2.opens a single xml file (dummy.xml) and re-writes the whole structure whenever they update their info..

That particular xml file(dummy.xml) contains all the information from a table(user_info) from the database.

my question is what if there are two or more members updating their info at the same time (in-directly attempting to update the dummy.xml file at the same time) would that be a problem? like one of the member didnt get their info updated on the xml ?

do let me know if you need to look at the codes :)

Question:
Why do you want to use xml if you have a mysql connection?

And take a look at this:

another thing that you can do is look how long it takes toi create an xml file if it's about 0.00001 sec don't worry about it.

create a microtime var at the beginning and the end and write it to the file then you know
