What if PHPCMS does not support the fsockopen function? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

1. When installing, directly change "step=3" in the address bar, and skip this step.

2. Replace fsockopen function with pfsockopen function

3. Modify the code in "client.class.php".

PHP fsockopen function description

Syntax:

Resource fsockopen (string $hostname [, int KaTeX parse error: Expected 'EOF', got' &'at position 20:... =-1 [, int & float errno [, string & $errstr [, float $timeout = ini_get ("default_socket_timeout")])

Turn on the function PHP fsockopen

PHP fsockopen requires the allow_url_fopen option in PHP.ini to be enabled.

Allow_url_fopen = On

Parameters:

Hostname if OpenSSL is installed, you may want to add the access protocol ssl:// or tls://, in front of your host name and address so that you can connect to the remote host using SSL or TLS clients based on the TCP/IP protocol.

Port port number. If you pass a-1 to this parameter, the port is not used, for example, unix://.

Errno if the return value of errno is 0 and the return value of this function is FALSE, this indicates that the error occurred before the socket connection (connect ()) was called, and the most likely cause of connection failure is an error initializing the socket.

The errstr error message is returned as a string of information.

Timeout sets the duration of the connection in seconds.

Return value:

Fsockopen () returns a file handle that can then be called by other file class functions (for example: fgets (), fgetss (), fwrite (), fclose (), and feof ()). If the call fails, FALSE is returned.
