How do I create an associative array from dynamic variables in php?

Question

I have this code:

$people=array();
$i=0;
foreach ($xml->xpath('//person') as $character) {
if ($character->status!="Active"){

  $people[$i]['fullname']=(string)$character->fullname;
  $people[$i]['status']=(string)$character->status;
  $i++;

    }
}

It creates an array with numeric keys, based on the value of $i. However, I don't actually want that, I want the "fullname" string to be the key but I can't work out how to dynamically assign the key. I was trying things like:

$people[(string)$character->fullname]=>(string)$character->status;

but this just throws errors. I can't work out how to create keys based on variables. Can anyone help, please?

Answer 1

再试一次，但是用= ，而不是=> ：

$people[ (string) $character->fullname ] = (string) $character->status;

Answer 2

You only use => in the Array definition. Otherwise just use bog-standard assignment:

$people[$character->fullname] = $character->status;

You don't need the casts, as you already have strings. Even if you didn't, you could simply rely on the dynamic typing to convert them as needed on output.

Answer 3

$people[$character->fullname] = (string)$character->status;
