Example code that pings a locally started IPFS daemon with disabled encryption, i.e.ipfs daemon --disable-transport-encryption

seba1337/php-ipfs-ping/blob/master/ping.php

<?php

//First we implement basic functions to read/write the first part of the protocol

/* gm($data): function for generating messages
	$data: data to be sent

   it appends to the start of the data string a byte value of the length of the string
   i.e. if we want to write "abc", so string length of 3
   it will return the string "\0x03" . "abc"

   this function is valid up to length of 254, above is more complex
*/
function gm($data) {
	$len = strlen($data);
	return chr($len) . $data; //we return length byte and data
}

/* rm(): function for reading messages
   it reads first the first byte, which is the length of the message
