 PHP date time, var_dump, include, require, session এর ব্যবহার। এই lesson এ আমরা দেখব কিভাবে  PHP তে date-time, var_dump, include, require, session ব্যবহার করতে হয় 

 

Source Code:

Date time:

date_default_timezone_set('Asia/Dhaka');

echo date("Y-m-d h:i:sa");
echo "<br/>";
echo date("d M Y");
echo "<br/>";
echo date("Y-m-d");

 

var_dump:

$a = 12;
var_dump($a);


$b = true;
var_dump($b);
exit;

echo "<pre>";
$arr = [12, 45, 'gdf'];
var_dump($arr);
echo "</pre>";

 

Include:

<!DOCTYPE html>
<html>
<head>
	<title> This is main page </title>
</head>
<body>

	<?php
		// require 'page.php';
		include 'header.php';
		include 'date.php';
	?>

</body>
</html>

 

Require:

<!DOCTYPE html>
<html>
<head>
	<title> Another page </title>
</head>
<body>

	<?php require 'header.php'; ?>

</body>
</html>

 

Session:

set_session.php

session_start();

$_SESSION['name'] = "My name";

 

test_session.php

session_start();
if (isset($_SESSION['name'])) {
	echo $_SESSION['name'];
} else {
	echo 'Please set the session';
}

<?php
session_start();

if (!isset($_SESSION['name'])) {
	header('Location: main.php');
