轉換爲關聯數組PHP

Question

如果你有這樣的數據：

1=Books 
1.1=Action & Adventure 
1.2=Arts, Film & Photography 
1.2.1=Architecture 
1.2.2=Cinema & Broadcast 
1.2.3=Dance 

上的數據的數量指標。你怎麼能把它放在關聯數組中？我想知道關聯數組的一個例子。由於

Answer 1

可與explode()和foreach

步驟來完成：

1）首先用爆炸換行字符\n的字符串。

2）在它上面。

3）你會得到單獨的行，用=爆炸（）它。

4）您將得到所需的密鑰0和價值1。

5）將它作爲鍵值對存儲在數組中。 完成

$str = '1=Books 
1.1=Action & Adventure 
1.2=Arts, Film & Photography 
1.2.1=Architecture 
1.2.2=Cinema & Broadcast 
1.2.3=Dance'; 
$arr = explode("\n", $str); 
$assoc = array(); 
if (! empty($arr)) { 
foreach ($arr as $k => $v) { 
    $temp = explode('=', $v); 
    $assoc[$temp[0]] = $temp[1]; 
} 
} 
echo '<pre>';print_r($assoc);echo '</pre>'; 

輸出：

Array 
(
[1] => Books 
[1.1] => Action & Adventure 
[1.2] => Arts, Film & Photography 
[1.2.1] => Architecture 
[1.2.2] => Cinema & Broadcast 
 [1.2.3] => Dance 
) 

Answer 2

可以通過將串進行成query string格式，然後使用parse_str() 必須插入1.0 =>圖書（append.0） 和1.2 .0 =>藝術，電影&攝影（追加.0）

$str = '1.0=Books 
    1.1=Action & Adventure 
    1.2.0=Arts, Film & Photography 
    1.2.1=Architecture 
    1.2.2=Cinema & Broadcast 
    1.2.3=Dance';<br /> 
    //replace & with and because parse_str not work with '&' 
    $str = str_replace('&','and',$str); 
    $str_ar = explode("\n",$str); 
    foreach($str_ar as $line){ 
     $aar .= 'a'; 
     $line_ar = explode('=',$line); 
     $array_index = explode('.',$line_ar[0]); 
     foreach($array_index as $index){ 
      $aar .= '['.$index.']'; 
     } 
     $aar.='='.($line_ar[1]).'&'; 
    } 
    $aar = rtrim($aar,'&'); 
    parse_str($aar,$o); 
    $o=array_shift($o); 

輸出

 
Array 
(
    [1] => Array 
     (
      [0] => Books 
      [1] => Action and Adventure 
      [2] => Array 
       (
        [0] => Arts, Film and Photography 
        [1] => Architecture 
        [2] => Cinema and Broadcast 
        [3] => Dance 
       ) 

     )
