How to set my info.php to avoid quotes errors?

Hi

I am in the process of learning PHP and I am following examples in a
book. I copy the examples from their website and paste them in my
editor.
When I run them I get errors galore. I found out it was the quotes,
they use double quotes most of the time and by replacing with single
quotes the errors are gone.
My question is, what do I need to change in my info.php to prevent
these errors until I am done with the book (I will switch back when I
am done with the book as I know single quotes are better.)?
It takes me too long to replace each quote.
I use the xampp package for apache,PHP, mysql if that matters.
And if you need to know my magic quotes settings, here they are:
magic_quotes_gpc On On
magic_quotes_runtime Off Off
magic_quotes_sybase Off Off

I did "google" my question but couldn't get anything that would help.

Thanks a lot
