    $catarray[Val]="row[ID]";
$row[ID] = "it works,";
 
echo ${$catarray[Val]};  // outputs nothing
echo $row[ID];  //  outputs "  it works "
    PHP:
    I'm trying to construct variables in a function that dynamically constructs a table populated with MySQL.

    I need access to the array taken out of the MySQL database.

    Any ideas why this one doesn'twork?

    Doesn't work because you are searching for a one dimensional variable with the name $row[id], not the 'id' element of the array $row.

    Why don't you do it like this? It seems variable variables are not necessary for what you are trying to do... 
    $catarray['Val'] = 'ID';
$row['ID'] = 'it works';
 
echo $row[$catarray['Val']];
