在PHP中增加多个变量For循环

Question

I have a code that separates first from last names, that I am using on a form that could have up to ten names. Right now I have simply replicated the code multiple times, manually updating the number, but figure there has to be a way to loop this function.

The basic code is:

if (!empty($_POST['name2'])) {
    $name2 = ucwords(strtolower($_POST['name2']));
    $parser = new HumanNameParser_Parser($name2);
    $fname2 = $parser->getFirst();
    $lname2 = $parser->getLast();
}

As the fname and lname variables are used elsewhere I need to stick with the naming.

I was thinking to use a For:

for ($i=2; $i <= 6; $i++)
{
    if (!empty($_POST['name($i)'])) {
        $name($i) = ucwords(strtolower($_POST['name($i)']));
        $parser = new HumanNameParser_Parser($name($i));
        $fname($i) = $parser->getFirst();
        $lname($i) = $parser->getLast();
    }
    else
    {
        break;
    }
}

But I am having a tough time figuring what I should actually use for the ($i) in my example. I tried .$i and [$i] but keep getting errors. And not sure if the way I should code it in the $_POST would be different than the variable $name.

Answer 1

for the $_POST variable you can use $_POST['name' . $i] and for the name variable you can just replace it with ${'name' . $i};

so it will be like this

for ($i=2; $i <= 6; $i++)
{
if (!empty($_POST['name' . $i])) {
    ${'name' . $i} = ucwords(strtolower($_POST['name' . $i]));
    $parser = new HumanNameParser_Parser(${'name' . $i});
    ${'fname' . $i} = $parser->getFirst();
    ${'lname' . $i} = $parser->getLast();
  }  
else 
  { 
    break;
  }
}
