MySQL insert inside foreach only being called once - php

Question

I have an array $alert_note. I iterate through a loop and fill it up with a few strings:
$n = 0;
$alert_note = array();
$results = array();
while($row = mysqli_fetch_assoc($query)){
//some code in here populates the $results[$n] array with results from $row
$thisnote = "<b>Location alert</b><br>
Alert ID: {$results[$n]['alert-id']}<br>
Start: {$results[$n]['start-formatted']}<br>
End: {$results[$n]['end-formatted']}<br>
Radius: {$results[$n]['radius-km']} km<br>
Distance: {$results[$n]['distance-km']} km<br>
<ul>\n";
//$results[$n]['data'] is a nested array, so iterate through it:
foreach($results[$n]['data'] as $name => $data){
$thisnote .= "<li>$name: $data</li>\n";
}
$thisnote .= "</ul>";
$alert_note[$n] = $thisnote;
$n++;
}
Then I call a foreach function:
foreach($alert_note as $alert_note_contents){
error_log("Note: $alert_note_contents");
mysqli_query($dblink, "INSERT INTO `incident_events` (`incident`, `data`, `time`, `operator`) VALUES ('$incident', '$alert_note_contents', '$now', '$operator')");
}
Each string in $alert_note shows up as expected in the PHP error log, but only the last one is inserted into the MySQL table. No PHP errors are being thrown. Any ideas why this may be?

Answer 1

plz before foreach($alert_note as $alert_note_contents){
do this so i can get the error
var_dump($alert_note );
and do this plz so i can see if there is any error ind db
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error)
{ die("Connection failed: " . $conn->connect_error); }
$sql = "INSERT INTO incident_events (incident, data, time, operator) VALUES ('$incident', '$alert_note_contents', '$now', '$operator')";
if ($conn->query($sql) === TRUE)
{ echo "New record created successfully"; }
else { echo "Error: " . $sql . "<br>" . $conn->error; }
$conn->close();
