Seems it should be simple, but how does one extract values from an array
and assign them to a variable?
foreach ($categoriesIN as $category) {
    echo "$category<br>";
foreach( $_POST['categoriesIN'] as $key => $value) {
    echo "value = $value<br>";
both show the values entered in the form but do not create a variable.
Since the number of entries will vary, I cannot assign a number of
variable names before knowing how many entries there may be.
