Is there a way to make this syntax: $checking_answer = $answer_reference_2; Equal to: $checking_answer = $answer_reference_ . ($i + 1); (where $i = 1) making $checking_answer take on the value of $answer_reference_2 ? I am trying to develop a web app quiz and I need to test the users answers. Ron The Verse of the Day “Encouragement from God’s Word” http://www.TheVerseOfTheDay.infoGive this a try <?php # Variable Variables Test $id_0 = 'zero'; $id_1 = 'one'; $id_2 = 'two'; $id_3 = 'three'; for ( $i=0; $i<4; $i++ ) {
echo ${'id_'.$i};
