这是一个代码示例，其行为与
不同import facebook
import warnings
# Hide deprecation warnings. The facebook module isn't that up-to-date (facebook.GraphAPIError).
warnings.filterwarnings('ignore', category=DeprecationWarning)
# Parameters of your app and the id of the profile you want to mess with.
FACEBOOK_APP_ID = 'SECRET'
FACEBOOK_APP_SECRET = 'SECRET'
FACEBOOK_PROFILE_ID = 'SECRET'
fb_api=facebook.GraphAPI()
api_token=fb_api.get_app_access_token(app_id=FACEBOOK_APP_ID, app_secret=FACEBOOK_APP_SECRET, offline=True)
graph = facebook.GraphAPI(api_token)
# Try to post something on the wall.
try:
fb_response = graph.put_object(parent_object=FACEBOOK_PROFILE_ID, connection_name='feed',
message='Hello, world')
print(fb_response)
except facebook.GraphAPIError as e:
print('Something went wrong:', e.type, e.message)
phpbrew's php 7.1.5
docker container with php 7.1.15$ DOMDocument = new DOMDocument;
$ elementMarkup = mb_convert_encoding（$ elementMarkup，＆＃39; HTML-ENTITIES＆＃39;，＆＃39; UTF-8＆＃39;）;
$上一层＆GT; loadHTML（$ elementMarkup）;
$上一层＆GT; removeChild之（$上一层＆GT;！DOCTYPE）;
$ DOMDocument-＆gt; replaceChild（$ DOMDocument-＆gt; firstChild-＆gt; firstChild-＆gt; firstChild，$ DOMDocument-＆gt; firstChild）;
$elementMarkup = '
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
</body>
</html>
';
显示不正确的行为
它应该是$DOMDocument->firstChild->firstChild->firstChild（来自xdebug的Nodenames：html-head-meta）和phpbrew的php工作正常。
但是dockerized php cathes meta（Nodenames：html-＃text-null）。
