Checking set/empty conditions for POSTed variables for each point in an array (yup two comments at
once) was acheived as follows using isset:
<?
$formvars = array(var1, var2, var3, var4);
/* Note '$' has been removed from vars. */
foreach ($formvars as $var) {
if (isset(${$var})) {
print $var."has been set to". ${$var};
}}
?>
Please forgive spacing.
