Variable representation


I am trying to represent the variable:
$row['Bible_knowledge_phrase_solver_game_question_topics_1'] 
Where the # 1 is replaced by a variable --- $i

The following code executes without an error, but “Hello world” doesn’t show on the screen.

<?php

$row['Bible_knowledge_phrase_solver_game_question_topics_1'] = "hello world";

$i = 1;

echo ${"row['Bible_knowledge_phrase_solver_game_question_topics_$i']"};

?>

What needs to change?  Ron

Re: Variable representation

or you can do this
echo $row["Bible_knowledge_phrase_solver_game_question_topics_$i"];
