PHP將數組作爲字典存儲，如何獲取密鑰和值？

Question

這看起來很簡單，但我的谷歌搜索似乎是關閉以得到正確的答案：

我動態形成陣列

$data = array(); 

$data['this is text'] = 1312; 
$data['heres more text'] = 191; 
$data['im also a unique entry'] = 239 

然後我想通過每個項目，並拿到鑰匙，並值：

foreach($data as $datapoint) 
{ 
    var_dump($datapoint); //this seems to just be the value 
    $k = key($garavg); //this does not work because datapoint is a value not an array 
} 

我只是希望能夠做到這一點：

echo "$key has this many entries $value"; 

Answer 1

foreach有建於：

foreach($data as $key => $value) 
{ 
    echo "$key has this many entries $value"; 
}
