php return stops the loop - php

Question

good day I write a function where I want to display the records which will match on the dates last week but it only loop one time. Is there a way to return all the dates and show all the records that will match with the dates? Here is my code.
function fetch_week(){
$today = date('F d Y');
for($i = 1; $i <= 7; $i++)
{
$repeat = strtotime("-1 day",strtotime($today));
$today = date('F d Y',$repeat);
$output = '';
$conn = mysqli_connect("localhost", "root", "", "sample");
$sql = "SELECT * FROM list WHERE datee = '".$today."' ORDER BY id DESC";
$result = mysqli_query($conn, $sql);
if(empty(mysqli_num_rows($result))){
echo '<td colspan="6"><h5><center>NO RECORDS.</center></h5></td>';
}
else{
while($row = mysqli_fetch_assoc($result)){
$output .= '<tbody id="appTable">
<tr class="content" style="font-weight: normal text-align: center">
<td>'.$row["name"].'</td>
<td>'.$row["address"].'</td>
<td>'.$row["contact"].'</td>
<td>'.$row["datee"].'</td>
</tr>
</tbody>
';
}
return $output;
}
}
}

You can create an array and return that after your loop ends. Check below code:
function fetch_week() {
$today = date('F d Y');
$response = [];
for ($i = 1; $i <= 7; $i++) {
$repeat = strtotime("-1 day", strtotime($today));
$today = date('F d Y', $repeat);
$output = '';
$conn = mysqli_connect("localhost", "root", "", "sample");
$sql = "SELECT * FROM list WHERE datee = '" . $today . "' ORDER BY id DESC";
$result = mysqli_query($conn, $sql);
if (empty(mysqli_num_rows($result))) {
echo '<td colspan="6"><h5><center>NO RECORDS.</center></h5></td>';
} else {
$output = '<tbody id="appTable">';
while ($row = mysqli_fetch_assoc($result)) {
$output .= '<tr class="content" style="font-weight: normal text-align: center">
<td>' . $row["name"] . '</td>
<td>' . $row["address"] . '</td>
<td>' . $row["contact"] . '</td>
<td>' . $row["datee"] . '</td>
</tr>';
}
$output .= '</tbody>';
$response[] = $output;
}
}
return $response;
}
You need to loop through on output to print your data. But apart from all these, your code is widely open for SQL injection. Please be careful and do changes for that. Also you don't need to create tbody again and again in loop. You can do that first time only which I have changed in above code as well.
Hope it helps you.
