Hi, I'm still new to php and wondered if I can get some help with a free php script. (inserted below)
I am trying to get number of ocurrences from a given string and by date, but I'm stuck and not sure how to finish it. Thanks

<?php
//
// CONNECT TO THE DATABASE SERVER (use your credentials)
//

$db = new mysqli(localhost,root,password,my_db);

//
// GET THE VALUE TO SEARCH FROM FROM SUBMITTED FORM DATA
//
$search = isset($_GET['search']) ? $_GET['search'] : '';
//
// ADD THE WILDCARD CHARACTERS
//
$sqlSearch = '%'.$search.'%';

//
// PREPARE AND EXECUTE THE QUERY
//
$sql = "SELECT
dst, calldate
, COUNT(*) as total
FROM asterisk_cdr
WHERE tablefield LIKE '%given string%'
GROUP BY dst";

$stmt = $db->prepare($sql);
$stmt->bind_param('s', $sqlSearch);
$stmt->execute();
$res = $stmt->get_result();

//
// LOOP THROUGH THE RESULTS AND BUILD THE HTML OUTPUT
//
$output = "";
while ($row = $res->fetch_row()) {
$output .= "<tr><td>" . join('</td><td>', $row) . "</td></tr>\n";
}
?>
