In PHP, you can use the fsockopen()
function to open a socket connection. To check if the socket is open or closed, you can use the is_resource()
function.
Here's an example:
1 2 3 4 5 6 7 8 9 10 11 |
$host = 'example.com'; $port = 80; $socket = fsockopen($host, $port, $errno, $errstr, 10); if (is_resource($socket)) { echo "Socket is open"; fclose($socket); } else { echo "Socket is closed"; } |
In this example, fsockopen()
is used to open a socket connection to example.com
on port 80. If fsockopen()
returns a resource, it means the socket is open and is_resource()
will return true
. If the socket is open, you can perform server communication and then close the socket using fclose()
. Otherwise, if fsockopen()
does not return a resource, it means the socket is closed.
Note: The fsockopen()
function may require appropriate server settings or permissions to open the socket connection.

It's important to note that this method only checks if the socket connection was successfully established. It does not check the current status of the socket connection.
