PHP使用array_push向多维数组添加元素 [英] PHP add elements to multidimensional array with array_push
问题描述
我有一个多维数组$ md_array,我想将更多元素添加到子数组recipe_type和美食中,这些美食来自从表中读取数据的循环.
I have a multidimensional array $md_array and I want to add more elements to the sub-arrays recipe_type and cuisine coming from a loop that reads data from a table.
在循环中,我为每一行创建一个新表$ newdata:
In the loop, I create a new table $newdata for each row:
$newdata = array (
'wpseo_title' => 'test',
'wpseo_desc' => 'test',
'wpseo_metakey' => 'test'
);
然后,使用array_push()
我需要将$ newdata数组附加到以下多维数组:
and then, using array_push()
I need to append the $newdata arrays to the following multidimensional array:
$md_array= array (
'recipe_type' =>
array (
18 =>
array (
'wpseo_title' => 'Salads',
'wpseo_desc' => 'Hundreads of recipes for Salads',
'wpseo_metakey' => ''
),
19 =>
array (
'wpseo_title' => 'Main dishes',
'wpseo_desc' => 'Hundreads of recipes for Main dishes',
'wpseo_metakey' => ''
)
),
'cuisine' =>
array (
22 =>
array (
'wpseo_title' => 'Italian',
'wpseo_desc' => 'Secrets from Sicily in a click',
'wpseo_metakey' => ''
),
23 =>
array (
'wpseo_title' => 'Chinese',
'wpseo_desc' => 'Oriental dishes were never this easy to make',
'wpseo_metakey' => ''
),
24 =>
array (
'wpseo_title' => 'Greek',
'wpseo_desc' => 'Traditional Greek flavors in easy to make recipies',
'wpseo_metakey' => ''
)
)
);
使用array_push向食谱类型数组添加新元素(数组)的语法是什么?我永远无法绕过多维数组,我有点困惑.
Whats the syntax for adding a new element (array) to the recipe_type array with array_push? I could never get my head around multidimensional arrays and I'm a bit confused.
推荐答案
如果要在关联数组中以递增顺序添加数据,则可以执行以下操作:
if you want to add the data in the increment order inside your associative array you can do this:
$newdata = array (
'wpseo_title' => 'test',
'wpseo_desc' => 'test',
'wpseo_metakey' => 'test'
);
// for recipe
$md_array["recipe_type"][] = $newdata;
//for cuisine
$md_array["cuisine"][] = $newdata;
这将根据最后的索引添加到食谱或美食中.
this will get added to the recipe or cuisine depending on what was the last index.
当具有顺序索引:$ arr [0],$ ar [1]时,通常在数组中使用数组推.不能直接在关联数组中使用它.但是由于您的子数组具有这种索引,因此您仍然可以像这样使用它
Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this
array_push($md_array["cuisine"],$newdata);
