using variable within variable kinda thing - help needed

    OK, let's check this out hey?

    
<?
$link_1 = "1__Text1";
$link_2 = "2__Text2";
$link_3 = "3__Text3";
$counter = 3;
/*Invalid Code Here
$value = explode(__,$link_.$counter);
*/
?>
    PHP:
    Now I want to explode it to separate
    number and text, however I want to use the variable for exploding() to be $link_number, and I have tried $link_.$counter, $link_{$counter} and more variations, including escaping the variable: $freshlink = "\$link_".$counter."";

    So a nudge in the right direction would prove incredibly helpful,

    Thanks,

    BP

    ${"link_$counter"}

    Something like...

    $value = explode ( __, ${link . '_' . $counter} );

    Yup it works (selling_vcc). I didn't know you could do things like that with PHP, thanks a lot man.

    Dataman, your method also works, but I prefer selling_vcc's vecause it looks cleaner.

    Thanks both, rep added,
