'Unescaping' strings in PHP

Question

Simple question. I have a program that uses AJAX to send data from an HTML form to a PHP script that creates a PDF. If a user inputs a value on the HTML form that has an apostrophe it's encoded/escaped with a backslash. For instance, 'Joe's' becomes 'Joe\s'

How can remove the backslash? I suppose I could use str_replace('\', '', $input) but I'm wondering what a broader approach to 'unescaping' a string is in PHP.

Disable MAGIC_QUOTES.

Normal use of Ajax will not add slash characters to data.

The most likely source of them is magic quotes (which are evil). Turn them off.

It would be nice to explain why they should be disabled

The magic quotes documentation (which I linked to) explains their drawbacks.

Just use stripslashes($input);
