Is it possible to use variable variables from form values inside a function.
For example when submitting form values, this works fine:
foreach($_POST as $key=>$value) {
if (empty($$key)) {
print "empty value $key<br>";
}
}
but, this doesn't:
function myFunction() {
foreach($_POST as $key=>$value) {
if (empty($$key)) {
print "empty value $key<br>";
}
}
}
Anyone dealt with this?
