EPG PHP script

EPG stands for Electronic Program Guide. It is a feature that is available on many TVs and other devices that allows you to view a list of the current and upcoming programs that are available on a particular TV channel or network. The EPG typically includes information such as the name of the program, the time it is scheduled to air, and a brief description of the program. It can be accessed through the TV’s menu or by pressing a dedicated button on the remote control. The EPG can be a useful tool for finding and scheduling your favorite shows and for discovering new programs that you may be interested in.

The script extract the data from the below links:

• The first thing the script does is set the default timezone to UTC using the date_default_timezone_set() function. This ensures that the current date and time is retrieved in the UTC timezone.
• The script then retrieves the current date and time in the format “YYYYMMDDHHmm” using the date() function, and stores it in the variable $now. This value will be used later to check if a program is currently airing or starts later today.
• Next, the script checks if the GET request has been made using the isset() function and the $_GET array. If the GET request has been made, the script extracts the channelId parameter from the $_GET array and stores it in the variable $channelId.
• The script then creates a new XMLReader object and opens the XML file at the specified URL using the open() method.
• The script enters a loop that reads the XML file incrementally using the read() method of the XMLReader object. At each iteration, the script checks the type and name of the current node using the nodeType and name properties of the XMLReader object.
• If the current node is a “channel” element, the script loads the element into a SimpleXMLElement object using the readOuterXML() method of the XMLReader object, and extracts the id attribute of the element. If the id attribute matches the channelId parameter passed in the GET request, the script extracts the display-name, icon, and url elements of the channel element, and stores them in the variables $displayName, $iconUrl, and $url, respectively. It then checks if these variables are set, and if they are, it prints the channel information to the webpage.
• If the current node is a “programme” element, the script loads the element into a SimpleXMLElement object using the readOuterXML() method of the XMLReader object, and extracts the start and stop attributes of the element. It then converts these attributes to the desired format using the strtotime() and date() functions, and stores the result in the variables $formattedStartTime and $formattedStopTime. The script also extracts the channel attribute of the programme element, and stores it in the variable $programChannelId.
• If the $programChannelId variable matches the channelId parameter passed in the GET request, the script checks if the program is currently airing or starts later today by comparing the $startTime and $stopTime variables to the $now variable. If the program is currently airing or starts later today, the script extracts the title, desc, category, and icon elements of the programme element, and stores them in the variables $title, $description, $category, and iconUrl, respectively. It then prints the program information to the webpage.
• After the loop has finished executing, the script closes the XML file using the close() method of the XMLReader object.

To use this script, you would need to send a GET request to the script with the desired channel ID passed as a parameter. For example, if you wanted to get information about the channel with the ID “12345”, you would send a GET request to “localhost/epg.php?channelId=NameOfTheChannelID”.

The channelID shoud be the same as in the XML.

When the script receives the GET request, it will retrieve the XML file, parse it incrementally using an XMLReader object, and extract the information about the desired channel and its current program. It will then print this information to the webpage.

If the GET request is not made or if the specified channel ID is not found in the XML file, the script will not output any information.

EX:

Full script:

<?php

// Set the timezone to the desired timezone
date_default_timezone_set('UTC');

// Get the current date and time in the desired format
$now = date('YmdHi');

// Check if the GET request has been made

// Create a new XMLReader object
$reader = new XMLReader();

// Open the XML file

// Extract the channel ID
$currentChannelId = (string)$channel['id'];

// If the channel ID matches the one from the GET request

$formattedStopTime = date('H:i - d.m.Y', strtotime($stopTime));

// Extract the channel ID of the program
$programChannelId = (string)$program['channel'];

// If the channel ID of the program matches the one from the GET request
if ($programChannelId == $channelId) {
