PHP数组键值

Question

我有一个数组像这样

$data = array(
    "some"   => "163",
    "rand"  => "630",
    "om"    => "43",
    "words" => "924",
    "as"    => "4",
    "keys"  => "54"
);

如何将每个集合的键与其值相关联,如下所示:

foreach ($data as $stuff){
  $this->$stuff["key"] = $stuff["value"];
}

Answer 1

foreach ($data as $key => $value){
  echo "$key => $value\n";
}

Answer 2

foreach($data as $key => $value)
{
    // $key and $value variable are available here
    // First iteration values would be: $key = "some" and $value = "163"
}
