搜索栏和功能可显示每场比赛的更多信息

When entering query to the search bar and finding more than one match the checkbox reveals more details for the first match only.

<?php
$query = $_POST['query'];
$min_lenght = 3;
if(isset($_POST['query']) &&(strlen($_POST['query']) >= $min_length)){
        $query = htmlspecialchars($query);
        $query = mysql_real_escape_string($query);
        $raw_results = mysql_query("SELECT * FROM sales_properties WHERE 
        (`Address1` LIKE '%".$query."%') OR (`Address2` LIKE '%".$query."%')
        OR (`Address3` LIKE '%".$query."%') OR (`postcode` LIKE 
        '%".$query."%')") or die (mysql_error());
        if(mysql_num_rows($raw_results) > 0){
            while($results = mysql_fetch_array($raw_results)){
                echo
                "<br>".$results['Address1']." ".$results['Address2']." ".$results['Address3']."<input type='checkbox' id='myCheck' onclick='myFunction()'>".

                                        "<br>";
                                    }
                                }
                                else{ 
                                    echo "No results";
                                }
                            }
                            else{ 
                                echo "<br>"."Try searching by name or surname, minimum of ".$min_length . " characters are required. "."<br>";
                            }
                        ?> < script >
     function myFunction() {
         var checkBox = document.getElementById('myCheck');
         var text = document.getElementById('text');
         if (checkBox.checked == true) {
             text.style.display = 'block';
         } else {
             text.style.display = 'none';
         }
     } < /script>`enter code here`

The first checkbox works as intended, but the next ones after that is not working at all. Should I use "foreach".
