Echoing dynamic variables

Question

I have $Page1Title declared in a config file and I have $PageID declared on each individual page. How would I go about echoing the $Page1Title variable using the $PageID variable? Almost like this $PageTitle = $Page{$PageID}Title; type of thing?!

UPDATE:

Sorted it with

$PageTitle = 'Page'.$PageID.'Title';
<?=$$PageTitle?>

Answer 1

You can use var of var

$var = 'Page' . $i . 'Title';
echo $$var;
