Why not to use Magic Quotes.

Why not use Magic Quotes.

What is the difference in meaning between these two ways of phrasing that sentence? To me the first sentence sounds like it tells the reader that there are good reasons not to use Magic Quotes (a programming feature) and those reasons will be given. The second one sounds like a rhetorical question, something along the lines of "What the heck not? Let's use them!" Am I right?

Best Answer

The difference is in the way not affects the sentence due to the presence of the to.

Why (not to use) Magic Quotes.

(Why not) use Magic Quotes.

In the former, the not negates the to use, making the meaning an explanation of why using Magic Quotes is not something you want to do.

In the latter, the not negates the why, making the meaning a rhetorical question
