A list of conferences can be found at the Conferences-page on php.net.
There are two options for sending us the information that you want published about your conference.
The first, and preferred, method is to open a pull request against our website repository on Github. Fork and clone that repository, execute the bin/createNewsEntry script (php bin/createNewsEntry), follow the step-by-step instructions, and commit and push the generated changes, and open a pull request.
The second method is to send an email to the php.net webmaster mailing list containing the text you wish us to use, along with an optional logo file.
Note: if you are including a logo file then please keep the dimensions small, in the region of 250 pixels in any direction.
Any questions should be directed to the php.net webmaster mailing list.
