User notes may be edited or deleted for any reason, whether in the list above or not!
We have a simple conversion in place to convert the @ signs and dots in your
address. You may still want to include a part in the email address
that is understandable only by humans as our conversion can be performed in
the opposite direction. You may submit your email address as
user@NOSPAM.example.com
for example (which will be displayed
as user at NOSPAM dot example dot com
. If we remove your note we can
only send an email if you use your real email address.
Note that HTML tags are not allowed in the posts, but the note formatting is preserved. URLs will be turned into clickable links, PHP code blocks enclosed in the PHP tags <?php and ?> will be source highlighted automatically. So always enclose PHP snippets in these tags. Double-check that your note appears as you want during the preview; that's why it is there!
Please note that periodically the developers go through the notes and may incorporate information from them into the documentation. This means that any note submitted here becomes the property of the PHP Documentation Group and will be available under the same license as the documentation.
Your IP Address will be logged with the submitted note and made public on the PHP manual user notes mailing list. The IP address is logged as part of the notes moderation process, and won't be shown within the PHP manual itself.
It may take up to an hour for your note to appear in the documentation.
The SPAM challenge requires numbers to written out in English, so, an appropriate answer may be nine but not 9.
