This is an example of dynamic code, with variable global scope and variable variable used in array parsing and function calling: http://toto.php?num=127 // an example of accepted get var $arrGet = array('num'); // an example of accepted cookie var $arrCook = array('myid', 'myweb', 'whatever', 'bof'); //function to get cookies function cookieGet($varname){ if(isset($_COOKIE[$varname])) return $_COOKIE[$varname]; } // list of function and array to get var by different means $listVarArrGetFunc = array('arrGet' => 'urlGet', 'arrPost' => 'postGet', 'arrSess' => 'sessionGet', 'arrCook' => 'cookieGet', 'arrFileUp' => 'fileUploadGet' ); // dynamic function to get var by all means function byAllMeansGet($varname){ global $listVarArrGetFunc; foreach ($listVarArrGetFunc as $arrn => $fctn){ global $$arrn, $$fctn; if($arrn!='arrGlob'){ $arrayX = $$arrn; //echo "<br><br> arrn : $arrn -> $$arrn -> $arrayX &nbsp;"; //echo "fctn : $fctn &nbsp;<br>"; /* ************************************************************** * arrn : arrCook -> $arrCook -> Array fctn : cookieGet * *****************************************************************/ foreach ($arrayX as $varn){ //echo "&nbsp;&nbsp; varn : $varn -> "; $$varn = $fctn($varn); //echo $$varn .
