PHP，如何从数组中回显特定对象数据？
我在 WordPress 中使用这个：
$arr=get_post_meta($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] => )
)
如何回显（请不要使用 for、foreach 等）name_en 数据？即使 print_r ($arr->name_en); 也不起作用...我想它必须是类似 - echo $arr->name_en[0];代码> ???
I use this in wordpress:
$arr=get_post_meta($post->ID, false);
I receive this array:
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] => )
)
How do I echo (no for, foreach, etc please) name_en data? Even print_r ($arr->name_en); doesn't work... I suppose it has to be something like - echo $arr->name_en[0]; ???

它是一个或多个数组，因此：
或者如果您只想获取数据：
->运算符用于访问对象的属性。It is an array or arrays, so:
or if you only want to get the data:
The
->operator is for accessing properties of objects.echo $arr['name_en'][0]应该可以工作。echo $arr['name_en'][0]should work.这应该有效
等
this should work
etc
