What are Magic Quotes
    WarningThis feature has been
DEPRECATED as of PHP 5.3.0 and REMOVED
as of PHP 5.4.0.
 
    
     When on, all ' (single-quote), " 
     (double quote), \ (backslash) and NULL 
     characters are escaped with a backslash automatically.  This is identical
     to what addslashes() does.
    
    
     There are three magic quote directives:
    
    
     - 
      
       magic_quotes_gpc
      
      
       Affects HTTP Request data (GET, POST, and COOKIE). Cannot be set at 
       runtime, and defaults to on in PHP.
      
      
       See also get_magic_quotes_gpc().
      
     
- 
      
       magic_quotes_runtime
      
      
       If enabled, most functions that return data from an external source, 
       including databases and text files, will have quotes escaped with a 
       backslash. Can be set at runtime, and defaults to off
       in PHP.
      
      
       See also set_magic_quotes_runtime() and
       get_magic_quotes_runtime().
      
     
- 
      
       magic_quotes_sybase
      
      
       If enabled, a single-quote is escaped with a single-quote instead of a 
       backslash.  If on, it completely overrides 
       magic_quotes_gpc. Having 
       both directives enabled means only single quotes are escaped as 
       ''. Double quotes, backslashes and NULL's will 
       remain untouched and unescaped.
      
      
       See also ini_get() for retrieving its value.
