/* SafeExtract() * Extract GET, POST, COOKIE variables into gloabal (scope) * © Amit Arora <digitalamit dot com> * Permission give to use this code for Non-Commericial, Commericial use * It would be appreciated if you could provide a link to the site */ if (phpversion() < '4.1.0') { $_GET = &$HTTP_GET_VARS; // For compatibility with PHP 3.x $_POST = &$HTTP_POST_VARS; $_COOKIE = &$HTTP_COOKIE_VARS; } function SafeExtract() { global $_GET, $_POST, $_COOKIE; $bQuote = get_magic_quotes_gpc(); foreach( func_get_args() as $v ) { if( is_array( $v ) ) while( list( $key, $value ) = each( $v ) ) { switch ( $key ) { case 'any': if ( is_array( $value ) ) foreach ( $value as $e ) { if ( isset($_COOKIE[$e]) ) $GLOBALS[$e] = ($bQuote ? stripslashes($_COOKIE[$e]) : $_COOKIE[$e]); if ( isset($_POST[$e]) ) $GLOBALS[$e] = ($bQuote ? stripslashes($_POST[$e]) : $_POST[$e]); if ( isset($_GET[$e]) ) $GLOBALS[$e] = ($bQuote ? stripslashes($_GET[$e]): $_GET[$e]); } break; case 'get': if ( is_array( $value ) ) foreach ( $value as $e ) { if ( isset($_GET[$e]) ) { $GLOBALS[$e] = ($bQuote ? stripslashes($_GET[$e]): $_GET[$e]); } else { unset( $GLOBALS[$e] ); } } break; case 'post': if ( is_array( $value ) ) foreach ( $value as $e ) { if ( isset($_POST[$e]) ) { $GLOBALS[$e] = ($bQuote ? stripslashes($_POST[$e]) : $_POST[$e]); } else { unset( $GLOBALS[$e] ); } } break; case 'cookie': if ( is_array( $value ) ) foreach ( $value as $e ) { if ( isset($_COOKIE[$e]) ) { $GLOBALS[$e] = $_COOKIE[$e]; } else { unset( $GLOBALS[$e] ); } } break; } } } }
