Adding variable if conditions?!?

[jmansa]

I'm trying to figure out how to use string_replace or substr_replace to add an variabel to several of lines in my script.

I want to dynamicly look through my script and everytime i come across this:

users.php?ga=

I want to be able to add at the end of the line a "&con=1"

In my script the lines with the users.php?ga= could look different like this:

users.php?ga=start&id=15
users.php?ga=news&name=peter&age=35
users.php?ga=profile&id=1458
etc, etc...

At all these lines I want to add the "&con=1" at the end...

Can this be done???

In advance thanks :-)

assuming this is a one off thing, it would take me longer to write the script to do this than doing it by hand.
