'application/octet-stream',
'application/vnd.ms-excel',
'application/x-csv',
'text/x-csv',
'text/csv',
'application/csv',
'application/excel',
'application/vnd.msexcel',
'text/plain'
);
// Validate whether selected file is a CSV file
if (!empty($_FILES['file']['name']) && in_array($_FILES['file']['type'], $fileMimes))
{
// Open uploaded CSV file with read-only mode
$csvFile = fopen($_FILES['file']['tmp_name'], 'r');
// Skip the first line
fgetcsv($csvFile);
// Parse data from CSV file line by line
// Parse data from CSV file line by line
while (($getData = fgetcsv($csvFile, 10000, ",")) !== FALSE)
{
// Get row data
$name = $getData[0];
$email = $getData[1];
$phone = $getData[2];
$status = $getData[3];
// If user already exists in the database with the same email
$query = "SELECT id FROM users WHERE email = '" . $getData[1] . "'";
$check = mysqli_query($conn, $query);
if ($check->num_rows > 0)
{
mysqli_query($conn, "UPDATE users SET name = '" . $name . "', phone = '" . $phone . "', status = '" . $status . "', created_at = NOW() WHERE email = '" . $email . "'");
}
else
{
mysqli_query($conn, "INSERT INTO users (name, email, phone, created_at, updated_at, status) VALUES ('" . $name . "', '" . $email . "', '" . $phone . "', NOW(), NOW(), '" . $status . "')");
