[SOLVED] Do variables change instantly?

[SirChick]

Hey, quick question ... say i have something like this:

 

Lets say in my database Username = SirChick.

 

$Username = $row['Username']; // from a query

 

Then i put a query to change username later on in the script to be "Test".....

 

Then i do If($Username == 'Test') after wards...

 

will $Username have changed to Test or will it still remain SirChick because it was assigned before query change?

The DB will have the new value.  If you don't update $Username then how can it have the new value?  You would have to either re-query or update $Username the same time you do the update to the DB.

they will not change unless you assign a new value or it goes out of scope the "==" is a comparision operator the "=" is a assignment operator

So i would have to do $Username = $row['Username']; // from a query

a second time ?

That'd be pretty pointless. No need to query the database another time. Just use the same value that you used to update the database to change the value of the variable, $Username.
