Answer 1

検索文字列を使用して検索フォームを作成します。

$sql="SELECT * FROM test WHERE Name LIKE '%".trim($params['name'])."%'"; 

Answer 2

<?php if (!empty($_REQUEST['fname'])){ 
        $params['name']=$_REQUEST['salute']." ".$_REQUEST['fname']." ".$_REQUEST['lname']; 
        $sql="SELECT * FROM test WHERE Name LIKE '%".trim($params['name'])."%'"; 

        $records=mysqli_query($db->conn,$sql); 
          while($row=mysqli_fetch_assoc($records)){ ?>
