Hello everyone I have googled all day and I have not found a single result for what I am curious about.I am new to PHP. So new that I have never actually written the code. I am just doing research for when I do begin coding.How do you build a 'poke' feature?Like the one on Facebook.I want to practice PHP by developing a social site.I would like to have a 'hug','smack','kiss', and more for user interaction.Any help no matter how small is appreciated.
