Magic quotes was a feature of the PHP scripting language, wherein strings are automatically escaped—special characters are prefixed with a backslash—before being passed on. It was introduced to help newcomers write functioning SQL commands without requiring manual escaping.
PHP generally follows C syntax, with exceptions and enhancements for its main use in web development, which makes heavy use of string manipulation. PHP variables must be prefixed by "$". This allows PHP to perform string interpolation in double quoted strings, where backslash is supported as an escape character.

[3]Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth ...
