PHP的foreach數組問題

Question

我有它輸出數組：

stdClass Object ([firstName] => Rupert [headline] => Managing Director at 
READ Advisors [lastName] => Bowen-Jones [pictureUrl] => 
https://media.licdn.com/mpr/mprx/0_yrLwHnXDTWGSypSo- 
B_NHz9hiu52pMpoOAAqHzLxpolpijIEr9zbQvllDTL1xYj6g1FvFtBsywhL) 

而且我想挑選出每個項目：

foreach ($user_data as $key => $value) { 
echo "<br />" . $value['firstName'] . "<br />"; 
} 

但我發現了以下錯誤：

stdClass Object ([firstName] => Rupert [headline] => Managing Director at 
READ Advisors [lastName] => Bowen-Jones [pictureUrl] => 
https://media.licdn.com/mpr/mprx/0_yrLwHnXDTWGSypSo- 
B_NHz9hiu52pMpoOAAqHzLxpolpijIEr9zbQvllDTL1xYj6g1FvFtBsywhL)

假設$ USER_DATA是對象的數組

foreach ($user_data as $key => $value) { 
echo "<br />" . $value->firstName . "<br />"; 
}
