PHPのforeachアレイ問題

Question

私は出力配列を持っている：

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

そして、私は、各項目選び出すしようとしています：

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

をしかし、私は次のエラーを取得しています：

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

あなたの助けもいただければ幸い！ $のUSER_DATAを想定し ルパート

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