You’ll need AJAX to run using interval:

setInterval(ajaxFunction(), 5000); // 5 sec

And in that function you have to call AJAX

function showHint(str) {

if (str.length == 0) { // case that doesn't call AJAX (can be discluded)
    document.getElementById("txtHint").innerHTML = "";
    return;
} else {  // case that calls AJAX
    var xmlhttp = new XMLHttpRequest();
    xmlhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) { //successfully getting answer
            document.getElementById("txtHint").innerHTML = this.responseText; // this.responseText is answer you get
        }
    };
    xmlhttp.open("GET", "gethint.php?q=" + str, true); // your php file that works with recieved data and echoes answer
    xmlhttp.send();
}

}

AJAX part is just a random fragment from w3schools, if you are new to AJAX then just search for AJAX PHP
