多维数组 - 仅打印特定键值

Here is the output of my program var_dump($myvar):

How can i store all ["name"]s inside of ["product-size"] and ["shopping-pack"] in two separate simple arrays with the values of "slug" as key and "name" as value?

I've searched before and tried. the solutions didn't work.

You can use array_column

$product = array_column($myVar['product-size'],'name','slug');
print_r($product);

$shopping = array_column($myVar['shopping-pack'],'name','slug');
print_r($shopping);

http://php.net/manual/en/function.array-column.php

Maybe this help to you:

$arr = "your array output";
$count_prod = count($arr['f_shopping']['product-size']);
$count_shopp = count($arr['f_shopping']['shopping-pack']);
$newArray = array();

for ($i = 0; $i < $count_prod; $i++) {
    $slug = $arr['f_shopping']['product-size'][$i]['slug'];
    $name = $arr['f_shopping']['product-size'][$i]['name'];
    $newArray[]($slug -> $name);
}
for ($i = 0; $i < $count_shopp; $i++) {
    $slug = $arr['f_shopping']['shopping-pack'][$i]['slug'];
    $name = $arr['f_shopping']['shopping-pack'][$i]['name'];
    $newArray[]($slug -> $name);
}

print_r($newArray);
