I'm not familiar with the php-electrum-library, but your first order of business would be to:

1) create a testpage to see if php works fine... For example test.php

Code:

<?php
phpinfo();
?>

If this page doesn't load properly, there is a problem with your lamp setup to begin with...

2) look at your server logs, the apache errorlogs are usually located in /var/log/apache2/error.log
Tail the errorlog and reload the page

Code:

tail -f /var/log/apache2/error.log

if you see errors appearing, they should point you towards what's wrong, if you have no clue => google is your friend

3) see what's in your variable, there are 2 ways of doing this:

Code:

<?php
require_once'electrum.php';

$electrum = new Electrum('127.0.0.1', 7777);

$response = $electrum->getbalance();

echo "<pre>";
print_r($response);
echo "</pre>";
?>

Code:

var_dump($response);

BTW, did you verify the prereqs?

Php is works fine..

But "nginx" my error.log is this;

Code:

2017/02/23 09:33:24 [error] 776#0: *5 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Call to undefined function curl_init() in /var/www/html/electrum.php on line 39" while reading response header from upstream, client: 192.168.2.203, server: your_server_ip, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "192.168.2.158"

I'm working on raspberry pi and connect with ssh... Please helpp ??? :-\

Seems like

Code:

sudo apt-get install php5-curl

might do the trick ;) (at least, it might solve this issue... There is no guarantee that everything else will work, but you'll have to tackle one problem at a time)
(sollution = untested, i don't have a rPi running nginx, so i cannot test out the sollution)

don't forget to either restart nginx/php-fpm, or just to plain restart your box just to be sure...

I'm not familiar with this library, nor with the electrum json-rpc api (i always use the core implementation's json-rpc api), but judging from this page:
http://docs.electrum.org/en/latest/merchant.html#create-a-signed-payment-request

I suppose it has to be something like this:
$response = $electrum->addrequest(1, "test");

This is completely untested (i don't have an electrum daemon running, nor an nginx stack, nor a rPi,... So i can only point towards what i think might be a sollution... It's up to you to test and debug).
