过滤器＆amp;使用PHP将Array转换为String

Question

如何转换此数组：

的print_r（$ ARR）

Array (
    [131] => stdClass Object
        (
            [tid] => 131
            [vid] => 9
            [name] => apple
            [description] => 
            [weight] => 0
        )

    [112] => stdClass Object
        (
            [tid] => 112
            [vid] => 9
            [name] => cool
            [description] => 
            [weight] => 0
        )

    [113] => stdClass Object
        (
            [tid] => 113
            [vid] => 9
            [name] => wonderful
            [description] => 
            [weight] => 0
        )

)

进入这个：

apple cool wonderful

基本上取出数组的“name”变量并按顺序将其内爆。 我试过内爆，但我不知道如何只引用“名称”变量。

Answer 1

echo join(" ", array_map(create_function('$x', 'return $x->name;'), $arr));

是一种方法吗

Answer 2

$terms = array();
foreach($arr as $term) { $terms[] = $term->name; }
print implode($terms, ', ');
