Question

I have a form that gets its names for checkboxes dynamically. Is there a way to find out the names of the unknown variables? For example:

 foreach($value as $option){
            $html .= "<input type='checkbox' name='".$key."[]' value='$option'>".htmlspecialchars($option)."</input>";
    }

I need to know what the _POST[''] would be.

Answer 1

Use the predefined variable $_POST and loop over :

foreach($_POST as $key => $value)
{
    // $key will be the name
    // $value will be the value of $_POST[$key]
}
