PHP, how to echo specific object data from array?
提问by user6291275
I use this in wordpress:
我在wordpress中使用这个：
$arr=get_post_meta($post->ID, false);
I receive this array:
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] => )
)
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 $arr->name_en[0];???
我如何回显（请不要 for、foreach 等）name_en 数据？即使print_r ($arr->name_en);不起作用......我想它必须是这样的 - echo $arr->name_en[0];？？？
回答by Felix Kling
It is an array or arrays, so:
它是一个或多个数组，所以：
print_r($arr['name_en']);
or if you only want to get the data:
或者如果您只想获取数据：
echo $arr['name_en'][0];
The ->operator is for accessing properties of objects.
该->运算符用于访问对象的属性。
回答by tdammers
echo $arr['name_en'][0]should work.
echo $arr['name_en'][0]应该管用。
回答by Shuhad zaman
this should work
这应该有效
echo $arr[0]['year_completed'];
echo $arr[0]['designers'];
etc
等等
