EXAMPLES
       Example #1

	      get_magic_quotes_gpc(3) example

	      <?php
	      // If magic quotes are enabled
	      echo $_POST['lastname'];		   // O'reilly
	      echo addslashes($_POST['lastname']); // O\'reilly

	      // Usage across all PHP versions
	      if (get_magic_quotes_gpc()) {
		  $lastname = stripslashes($_POST['lastname']);
	      }
	      else {
		  $lastname = $_POST['lastname'];
	      }

	      // If using MySQL
	      $lastname = mysql_real_escape_string($lastname);

	      echo $lastname; // O'reilly
	      $sql = "INSERT INTO lastnames (lastname) VALUES ('$lastname')";
	      ?>

NOTES
       Note

	       If the directive  magic_quotes_sybase is ON it will completely override	magic_quotes_gpc.  So  even  when  get_magic_quotes_gpc(3)
	      returns  TRUE  neither double quotes, backslashes or NUL's will be escaped. Only single quotes will be escaped. In this case they'll
	      look like: ''
