顯示正確的數組

Question

我正在使用此函數以數組形式返回所有可用的圖像大小。

function king_image_size() { 
    $image_sizes = get_intermediate_image_sizes(); 
    foreach ($image_sizes as $tax) { 
    $image_sizes[$tax] = $tax; 
    } 
    return $image_sizes 
} 

但是，這複製了返回數組。輸出

array(18) { [0]=> string(9) "thumbnail" [1]=> string(6) "medium" [2]=> string(12) "medium_large" [3]=> string(5) "large" [4]=> string(9) "dhaka-por" [5]=> string(11) "dhaka-por-h" [6]=> string(15) "dhaka-landscape" [7]=> string(7) "dhaka-h" [8]=> string(8) "dhaka-sq" ["thumbnail"]=> string(9) "thumbnail" ["medium"]=> string(6) "medium" ["medium_large"]=> string(12) "medium_large" ["large"]=> string(5) "large" ["dhaka-por"]=> string(9) "dhaka-por" ["dhaka-por-h"]=> string(11) "dhaka-por-h" ["dhaka-landscape"]=> string(15) "dhaka-landscape" ["dhaka-h"]=> string(7) "dhaka-h" ["dhaka-sq"]=> string(8) "dhaka-sq" } 

Anotherway，我發現很常見，

function king_image_size() { 
    $image_sizes = get_intermediate_image_sizes(); 
    return $image_sizes; 
} 

然後我得到0,1,2,3 ......在頁面構建輸出。我需要的功能像

function king_image_size(){ 
    return array(
     'medium' => 'medium' , 
); 
}

所以，你只是想要一個數組，使用你得到的值，作爲密鑰以及...？

對於這一點，你可以簡單地使用array_combine，只是喂值數組中兩次：

function king_image_size() { 
    $image_sizes = get_intermediate_image_sizes(); 

    return array_combine($image_sizes, $image_sizes); 
}
