如何在multidimensionnal陣列（PHP）獲取鍵的值

Question

我有一個數組這樣的：

array(2) { 
    ["dashboard"]=> 
    array(3) { 
    ["controller"]=> 
    string(5) "Index" 
    ["action"]=> 
    string(5) "index" 
    ["path"]=> 
    string(34) "dashboard/user/example/{page}/{id}" 
    } 
    ["home"]=> 
    array(3) { 
    ["controller"]=> 
    string(5) "Index" 
    ["action"]=> 
    string(6) "second" 
    ["path"]=> 
    string(10) "home/index" 
    } 
} 

如何獲得陣列中所有的「路徑」的價值觀？ 我試圖在PHP中使用array_search和幾個函數，但這不起作用。

Answer 1

foreach($arr as $key=>$val){ 
    $path[] = $val['path']; //store all paths into an array 
    //$path[$key] = $val['path']; //you can use this also to keep whose path is this 
} 
var_dump($path); 

Answer 2

只需使用一個foreach循環：

$paths = array(); 

foreach($array as $page) { 
    $paths[] = $page['path']; 
} 

print_r($paths); 

Answer 3

@Adrien PAYEN簡單地使用array_column（）像下面，通過它可以得到所有值數組的特定列：

<?php 
    print_r(array_column($yourArray, "path"));
