    As far as getting the varibale name $abc is concerned i do not think there should be any problem..u can get the string stored in it.

    yes,but i think you may not get any function support for this.but if you want to get some variable names from form then it is possible using $HTTP_POST_VARS(see the manual for details).

    The above variable name you can get very easily..

    <?
    $test="hello";
    echo substr("$test",1);

    //returns the variable name.make sure that '' slash is thier before variable.

    //it will print 'test'
    ?>

    i don't know wether using some function you can achive samething..

    Good Luck!!!
