[php_mysql] Using eval

[Charlie Markwick]

I have the following select on a form which loops until all the records
are displayed:-

<input type="checkbox" name="frm<?php echo
$row_rsAddRangeUsers['UserGID']; ?>" 
        value="<?php echo $row_rsAddRangeUsers['UserGID']; ?>" />

When the form is submitted I want to recover the value of any check
boxes that are checked.

I am trying to use eval, so something like:-

if (isset(eval("\"\$frm\" . $row_rsAddRangeUsers['UserGID']"))) {

But this isn't working. What should the correct construction of the eval
statement be in order to be able to proceed?
