PHP and JavaScript together -

complete revision:

this code whole problem:

function inbox() {     #connecting:     include('config.php');     $myconnection = new pdo('mysql:host=x;dbname=x', $dbusername, $dbpassword);     $myconnection->setattribute(pdo::attr_errmode, pdo::errmode_exception);      #collecting:     $curuser = $_session['name'];      #searching:     $searchinbox = $myconnection->prepare("select * inbox = :username");     $searchinbox->bindparam(':username', $curuser);     $searchinbox->execute();     $foundresults = $searchinbox->fetch(pdo::fetch_both);     var_dump($foundresults);   } 

as add in 'searching' code, 404 error, if tries refer webpage.

a picture of database table 'inbox': when replace:

$searchinbox = $myconnection->prepare("select * inbox = :username"); 

to: $searchinbox = $myconnection->prepare("select * inbox title = welcome");

i following error:

fatal error: uncaught exception 'pdoexception' message 'sqlstate[42s22]: column not found: 1054 unknown column 'welcome' in 'where clause'' in (..) 

so, somehow can't read title column in case? , why not read whole 'to' column , returns 404 error?

if javascript able call php function , update inbox response take @ ajax. can use send parameters php file, receive response, , process response , update page javascript. if want, jquery has nice ajax function can use.
