PHP，如何从数组呼应特定对象的数据？ [英] PHP, how to echo specific object data from array?

问题描述

我在字preSS使用：

I use this in wordpress:

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

我收到此数组：

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（不为，的foreach等请）name_en数据？即使的print_r（$ arr-＆GT; name_en）; 不工作......我想那一定是类似 - 回声$ arr- ＆GT; name_en [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]; ???

推荐答案

这是一个数组或数组，所以：

It is an array or arrays, so:

print_r($arr['name_en']);

或者如果你只想要得到的数据：

or if you only want to get the data:

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

的 - 方式＆gt; 运营商是访问属性的对象的

The -> operator is for accessing properties of objects.
