I have an issue while trying to get data from mysql using json array The Data stored has apostrophe ( ' ). And the output is always blank (no data) even is blocking the other rows from showing the data. My sql connection (database_connection.php):

<?php
$connect = new PDO("mysql:host=localhost;dbname=appointment_data", "root", "pass");
?>

my php file:

<?php
include('database_connection.php');

$query = "SELECT * FROM test ORDER BY id";
$statement = $connect->prepare($query);
if($statement->execute())
{
        while($row = $statement->fetch(PDO::FETCH_ASSOC))
        {
                $data[] = $row;
        }

        echo json_encode($data);
}

?>

is their any way to avoid this error without changing the SQL table
