                e.preventDefault(); //form will not submitted  
                $.ajax({  
                     url:"upload.php",  
                     method:"POST",  
                     data:new FormData(this),  
                     contentType:false,          // The content type used when sending data to the server.  
                     cache:false,                // To unable request pages to be cached  
                     processData:false,          // To send DOMDocument or non processed data file it is set to false  
                     success: function(data){  
                          if(data=='Error1')

                          else  
                          {

                          }  
                     }  
                })  
           });  
      });  
 </script>  

Step 5 – Create PHP File To Import Csv File Data Into Database

Create one file name upload.php; which is used to read csv file and insert all csv file data into MySQL database. So add the following code into upload.php file:

<?php
// Load the database configuration file
include_once 'db.php';

if(!empty($_FILES["file"]["name"]))
{

    // Allowed mime types
    $fileMimes = array(
        'text/x-comma-separated-values',
        'text/comma-separated-values',
        '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
            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 . "')");

                }
            }

            // Close opened CSV file
            fclose($csvFile);

            echo "Success";
        
    }
    else
    {
        echo "Error1";
    }
}else{
  echo "Error2";  
}
