PHP JSON not displaying MySQL result - php

Question

The PHP I created retrieve data from a MySQL database and turns it into a JSON which is then echoed. I had 300 records and the PHP was able to display the JSON and was visible when viewed.
However, I added another 100 records to the same table and for some reason the JSON isn't being displayed. It just appears blank with no error. But when I remove the 100 records, the JSON displays as normal.
I haven't touched the PHP file during this. What could the reason be?
<?PHP
include_once("connection.php");
$query = "select id,mosque_name,latitude,longitude from mosques;";
$result = mysqli_query($conn, $query);
if (mysqli_num_rows($result) > 0) {
$response["mosques"] = array();
while ($row = mysqli_fetch_array($result)) {
$mosque = array();
$mosque["id"] = $row["id"];
$mosque["mosque_name"] = $row["mosque_name"];
$mosque["latitude"] = $row["latitude"];
$mosque["longitude"] = $row["longitude"];
array_push($response["mosques"], $mosque);
}
$response["success"] = 1;
// echoing JSON response
echo json_encode($response);
} else {
$response["success"] = 0;
$response["message"] = "No mosques found";
echo json_encode($response);
}
?>

Try This:-
<?PHP
include_once("connection.php");
$query = "select id,mosque_name,latitude,longitude from mosques;";
$result = mysqli_query($conn, $query);
if (mysqli_num_rows($result) == 0) {
echo json_encode("");
}
else{
while ($row = mysqli_fetch_array($result)) {
/*$mosque = array();
$mosque["id"] = $row["id"];
$mosque["mosque_name"] = $row["mosque_name"];
$mosque["latitude"] = $row["latitude"];
$mosque["longitude"] = $row["longitude"];*/
$fetchRow[]=$row;
// array_push($response["mosques"], $mosque);
}
echo json_encode($fetchRow);
}
/* $response["success"] = 1;
echoing JSON response
echo json_encode($response);*/
?>
