    $publication_status = $data['publication_status'];
    $blog_long_description = $data['blog_long_description'];

    $path=  '../asset/admin/blog_image/';
    $target_image = $path.$files['blog_image']['name'];
    $file_type = pathinfo($target_image, PATHINFO_EXTENSION);
    $file_size = $files['blog_image']['size'];
    $check = getimagesize($files['blog_image']['tmp_name']);
    if ($check) {
        if (file_exists($target_image)) {
            echo 'Sorry File already exists.';
            exit();

                    echo 'Sorry your file type is not valid.';
                    exit();
                } else {

                        $stmt = $this->pdo->prepare($query);
                        $stmt->bindParam(':category_id', $category_id, PDO::PARAM_STR);
                        $stmt->bindParam(':blog_title', $blog_title, PDO::PARAM_STR);

In mysql i make column Name: post_time, Type: DATETIME. Is this correct?

How can view time as my desired format Time: 2:50 pm/am and date as Date: Aug 7 2016

Hi, here is the updated code which works fine. My question is how can i skip the first row of my .csv file which generally contains header( id, name, email, address).

<?php
include 'connection.php';

class Import {
    private $pdo;

    public function __construct() {     
        $obj_connection = new Db_connection();
        $this->pdo = $obj_connection->connection();     
    }

    public function import_csv() {

        $extension= end(explode(".", basename($_FILES['file']['name'])));
        if (isset($_FILES['file']) && $_FILES['file']['size'] < 10485760 && $extension=='csv') {
            $file = $_FILES['file']['tmp_name']; 
            $handle = fopen($file, "r"); 
            try {           
                while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {                   
                $importSQL = "INSERT INTO tbl_applicants ( application_no, applicant_name, applicant_email, applicant_mobile, applicant_address ) VALUES('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]')";
                $this->pdo->query($importSQL);  
                }
            }
            catch(PDOException $e) {
                echo $e->getMessage();
            }

        }
    }

}
