PHP,如何从数组中回显特定的对象数据？

Question

我在wordpress中使用它:

$arr=get_post_meta($post->ID, false);

我收到这个数组:

Array (
[_edit_last] => Array ( [0] => 2)
[year_completed] => Array ( [0] => 2010 )
[designers] => Array ( [0] => )
[developers] => Array ( [0] => )
[producers] => Array ( [0] => )
[_edit_lock] => Array ( [0] => 1298159324 )
[name_en] => Array ( [0] => game 1)
[name_et] => Array ( [0] => game 2 )
[friends_meta] => Array ( [0] => )
)

我如何回应(no for,foreach等)name_en数据？即使print_r ($arr->name_en);不起作用......我想它必须是这样的 - echo $arr->name_en[0];???

Answer 1

它是一个数组或数组,所以:

print_r($arr['name_en']);

或者如果您只想获取数据:

echo $arr['name_en'][0];

该->操作员是用于访问的属性的对象.
