Echo data not being displayed - php

Question

I am new to php development.I have created a database using phpmyadmin.Now i want all the data to be displayed on the page.But when ever i try to run the file nothing is showing up.I dont know why this is happening.
db_config.php
<?php
define('DB_USER', "root"); // db user
define('DB_PASSWORD', ""); // db password (mention your db password here)
define('DB_DATABASE', "moviesreview"); // database name
define('DB_SERVER', "localhost"); // db server
$con = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_DATABASE);
if($con->connect_errno > 0) {
die('Connection failed [' . $con->connect_error . ']');
}
db_connect.php
<?php
/**
* A class file to connect to database
*/
class DB_CONNECT {
// constructor
function __construct() {
// connecting to database
$this->connect();
}
// destructor
function __destruct() {
// closing db connection
$this->close();
}
/**
* Function to connect with database
*/
function connect() {
// import database connection variables
require_once __DIR__ . '/db_config.php';
// Connecting to mysql database
$con = mysqli_connect(DB_SERVER, DB_USER, DB_PASSWORD) or die(mysqli_error($con));
// Selecing database
$db = mysqli_select_db($con,DB_DATABASE) or die(mysqli_error()) or die(mysqli_error($con));
// returing connection cursor
return $con;
}
/**
* Function to close db connection
*/
function close() {
// closing db connection
mysql_close();
}
}
?>
Code
<?php
$response = array();
// include db connect class
require_once __DIR__ . '/db_connect.php';
$con=new db_connect();
$strQuery="SELECT * FROM `moviesdetails WHERE `recent_upcoming` =0";
$result=mysqli_query($con,$strQuery);
while($row=mysqli_fetch_array($result)){
$row_array['movies_id']=$row['movies_id'];
$row_array['movies_name']=$row['movies_name'];
$row_array['movies_description']=$row['movies_description'];
$row_array['movies_time']=$row['movies_time'];
$row_array['movies_release_date']=$row['movies_release_date'];
$row_array['movies_youtube_link']=$row['movies_youtube_link'];
$row_array['recent_upcoming']=$row['recent_upcoming'];
$row_array['movies_image']=$row['movies_image'];
$row_array['movies_actors']=$row['movies_actors'];
array_push($response,$row_array);
}
echo json_encode($response);
?>
Error what i am getting

Answer 1

There are a few things wrong with your code.
The space between <? and php
A missing tick for your table, and a missing semi-colon for your query.
A missing DB connection link.
Your code:
<? php
^ space
$response = array();
// include db connect class
require_once __DIR__ . '/db_connect.php';
$strQuery="SELECT * FROM `moviesdetails WHERE `recent_upcoming` =0"
^ ^
$result=mysqli_query($strQuery);
^ no DB connection
<?php
$response = array();
// include db connect class
require_once __DIR__ . '/db_connect.php';
$strQuery="SELECT * FROM `moviesdetails` WHERE `recent_upcoming` =0";
$result=mysqli_query($con,$strQuery);
Using error reporting http://php.net/manual/en/function.error-reporting.php would have signaled that, including or die(mysqli_error($con)) to mysqli_query()
You've edited your question. You are mixing mysqli_ and mysql_ functions. They do not mix.
All mysql_error should be mysqli_error($con) and mysql_close() to mysqli_close($con)
Edit:
Replace the entire contents of db_connect.php with the following:
<?php
define('DB_USER', "root"); // db user
define('DB_PASSWORD', ""); // db password (mention your db password here)
define('DB_DATABASE', "moviesdetails"); // database name
define('DB_SERVER', "localhost"); // db server
$con = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_DATABASE);
if($con->connect_errno > 0) {
die('Connection failed [' . $con->connect_error . ']');
}
Edit #2:
while($row=mysqli_fetch_array($result)){
$response[] = $row;
$row['movies_id'];
$row['movies_name'];
$row['movies_description'];
$row['movies_time'];
$row['movies_release_date'];
$row['movies_youtube_link'];
$row['recent_upcoming'];
$row['movies_image'];
$row['movies_actors'];
}
echo json_encode($response);

Answer 2

You have missing connection link as parameter in your mysqli_query() function. Should be:
$result = mysqli_query($connection_link, $strQuery);
http://php.net/manual/en/mysqli.query.php
$connection_link will have in this case following format:
// include db connect class
require_once __DIR__ . '/db_connect.php';
$connection_link = new DB_CONNECT();
But as #Fred -ii- said in comments, you have some syntax errors in PHP and SQL query too.
Your DB class is badly designed, you should store connection link in property and making queries through this class.
