I have a rather big php site, which was written for php4 and register_globals enabled. It is old custom CMS. Now I want to run it on the php5 hosting without register_globals. Is it possible to change parameters parsing from $id to $_GET[“id”] automatically, with some script?
I can get parameters names from wget -r on this site.
It have dozens of php scripts, and it is not very easy to do this change manually.
PS: UPDATE: I want to convert only GET variables. The additional line is $var_name = $_GET["var_name"] for each parameter. This line should be inserted very high in the script, e.g. by adding a new <? ?> section at very top.
Although the actual finding/replacing might take more time, doing this manually will most likely result in less bugs / weird behaviour.
If are not the original author of the application, then this manual finding/replacing is also an opportunity for you to become much more familiar with the codebase than some automatic method.
Automatic: fast, almost definitely will result in some horrible bugs
Manual: slower (likely), almost definitely will result in better understanding, less bugs – and any bugs that are introduced will be easier to fix because of your better understanding.
