Today, the editor will share with you the relevant knowledge about how to use server scripts to send messages. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article, let's take a look at it.

Let's create a PHP file named "server_time.php" and type the following script into it. It will only periodically report the current time of the built-in clock on the Web server. We will retrieve that time and update the page accordingly later in this tutorial.

Example download

The first two lines of the PHP script set two important headers. First, it sets the MIME type to text/event-stream, which is required by the server-side event standard. The second line tells the Web server to turn off caching, otherwise the output of the script may be cached.

Each message sent by an event sent through the HTML5 server must begin with the text data:, followed by the actual message text and newline sequence (\ n\ n).

Finally, we use the PHPflush () function to ensure that the data is sent immediately, rather than buffering the data until the PHP code is complete.
