I have to send a string from an HTML page to a specific ip and port address using PHP.
Example: clicking on a button(on my HTML site) should result in sending the string "hello" to port 7474 of ip x.x.x.x.
How can i do that with PHP?
Use fsockopen to open a connection to the port and get a filehandle, then use fwrite to write to that filehandle.
You’ll usually want to close the connection with fclose when you’re done. PHP will close the connection for you at the end of the script if you forget.
