PHP数组键的值

Question

我有一个阵列这样

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

我怎样才能得到每一组的关键与他们的价值观喜欢此相关：

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" 
}
