How to get output from php to typeahead?

I am using twitter typeahead and php as backend for getting data from mysql.But i am not able to see any suggestions when i start typing on the text box. i think because the php output has to be JSON encoded..

how can i encode the output

output:

echo '<a href="results.html" class="searchres" onclick="navigate()" style="color:#696969;text-decoration:none;"><img src='.$iurl.' class="icons" /><div class="results" style="color:#696969;text-decoration:none;">'."$fname".'</div><span style="color:#696969;text-decoration:none;" class="author">'.$caption.'</span></a>'."\n";

html:
