PHP, how to echo specific object data from array?

问题:

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]; ???

回答1:

It is an array or arrays, so:

print_r($arr['name_en']);

or if you only want to get the data:

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

The -> operator is for accessing properties of objects.

回答2:

echo $arr['name_en'][0] should work.

回答3:

this should work

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

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

etc
