In Topic: Problems drawing images with PHP GD

02 November 2020 - 05:06 PM

I understand but I want it to be solely based on PHP. It would be better if I could do it without any dependencies. And I'm trying to avoid any type of client-side scripts for now. But I'll do it for sure in the future.
The project I'm currently working on is "PHPML" which is a PHP implementation of some Python Machine Learning libraries (like NumPy, scipy, matplotlib, NLP, etc.) as the project is currently under development I don't want to mess with client-side. I want the users to just import one PHP Script on a page and access all the libraries.
But in the future if it becomes a need to include some javascripts for any reason I lok into it but for now I want to stick with PHP GD (if possible).

Is there any ways to host this on Tommy server?

Okay, so finally I've solved the problem. What I did is, changed the virtual-ssl-host configuration and httpd.conf. Here is the new configurations:

httpd-ahssl.conf/httpd-ssl.conf:
<VirtualHost _default_:443>
	SSLEngine on
	ServerName localhost:443
	SSLCertificateFile "${SRVROOT}/conf/ssl/localhost.crt"
	SSLCertificateKeyFile "${SRVROOT}/conf/ssl/localhost.pem"
	DocumentRoot "${SRVROOT}/htdocs"
	# DocumentRoot access handled globally in httpd.conf
	CustomLog "${SRVROOT}/logs/ssl_request.log" \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
	<Directory "${SRVROOT}/htdocs">
		Options Indexes Includes FollowSymLinks
		AllowOverride AuthConfig Limit FileInfo
		Require all granted
	</Directory>
	SSLProxyEngine on
	ProxyPass /ws/ ws://localhost:9000
	ProxyPassReverse /ws/ ws://localhost:9000
	ProxyRequests off
</VirtualHost>

<VirtualHost 192.168.1.201:443>
	DocumentRoot "${SRVROOT}/htdocs"
	ServerName 192.168.1.201
	SSLEngine on
	#SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
	SSLCipherSuite ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:DHE-RSA-AES128-SHA
	SSLCertificateFile "${SRVROOT}/conf/ssl/localhost.crt"
	SSLCertificateKeyFile "${SRVROOT}/conf/ssl/localhost.pem"
	SSLCertificateChainFile "${SRVROOT}/conf/ssl/ca-chain.pem"
	#SSLProxyCACertificateFile "${SRVROOT}/conf/ssl/localhost.crt"
	SSLProxyEngine on
	#SSLProxyVerify none
	#SSLProxyCheckPeerCN off
	#SSLProxyCheckPeerName off
	ProxyPass /ws/ ws://192.168.1.201:9000
	ProxyPassReverse /ws/ ws://192.168.1.201:9000
	ProxyRequests off
	ErrorLog "${SRVROOT}/logs/error.log"
	CustomLog "${SRVROOT}/logs/access.log" common
	LogLevel warn
</VirtualHost>

httpd.conf: (here I've just loaded almost all the modules related to mod_proxy)
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_express_module modules/mod_proxy_express.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
#LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
#LoadModule proxy_html_module modules/mod_proxy_html.so
LoadModule proxy_hcheck_module modules/mod_proxy_hcheck.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_http2_module modules/mod_proxy_http2.so
LoadModule proxy_scgi_module modules/mod_proxy_scgi.so
LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so
LoadModule watchdog_module modules/mod_watchdog.so
Thank you Krydos & wolstech sir for helping me out.


Now another question, you can see all the configurations I have, can I host the application in Heliohost?

Yes but the previous error which is always occurring in Firefox Console "Firefox can’t establish a connection to the server at wss://192.168.1.201/ws/." But this time another error was occurred "500 Proxy Error" and the "SSL_ERROR_RX_RECORD_TOO_LONG" error has gone but the WSS request is going through HTTPS instead of WSS. I've changed my client.js after setting up proxy. Here is the new one:
var colors = [
	'#007AFF','#FF7000','#FF7000','#15E25F','#CFC700','#CFC700','#CF1100','#CF00BE','#F00'
];
var color_pick = Math.floor(Math.random() * colors.length);

//create a new WebSocket object.
var msgBox = $('#message-box');
//var wsUri = "wss://localhost/ws/";
var wsUri = "wss://192.168.1.201/ws/";
//var wsUri = "wss://192.168.1.201:9000/server.php";
websocket = new WebSocket(wsUri);

websocket.readyStateChange = function (e) { // connection is open 
	console.log(e);
}

websocket.onopen = function (ev) { // connection is open 
	msgBox.append('<div class="system_msg" style="color:#bbbbbb">Welcome to my "Demo WebSocket Chat box"!</div>'); //notify user
}
// Message received from server
websocket.onmessage = function (ev) {
	var response = JSON.parse(ev.data); //PHP sends Json data

	
	
	var res_type = response.type; //message type
	var user_message = response.message; //message text
	var user_name = response.name; //user name
	var user_color = response.color; //color

console.log(res_type);
	switch (res_type) {
		case 'usermsg':
			if($("#user_typing").length > 0)
				$("#user_typing").remove();
			msgBox.append('<div><span class="user_name" style="color:' + user_color + '">' + user_name + '</span> : <span class="user_msg">' + user_message + '</span></div>');
			break;
		case 'system':
			msgBox.append('<div style="color:#bbbbbb">' + user_message + '</div>');
			break;
		case 'notification':
			var user_notification = response.notification; //notification type
			if(user_notification === 'typing'){
				if($("#user_typing").length <= 0)
					msgBox.append('<div id="user_typing"><span class="user_name" style="color:' + user_color + '">' + user_name + '</span> : <span class="system_msg">' + user_message + '</span></div>');
			} else
				msgBox.append('<div id="user_notification"><span class="user_name" style="color:' + user_color + '">' + user_name + '</span> : <span class="system_msg">' + user_message + '</span></div>');
			break;
	}
	msgBox[0].scrollTop = msgBox[0].scrollHeight; //scroll message 

};

websocket.onerror = function (e) {
	msgBox.append('<div class="system_error">Error Occurred - ' + e.data + '</div>');
};
websocket.onclose = function (e) {
	if(e.wasClean)
		msgBox.append('<div class="system_msg">Connection Closed</div>');
	else
		msgBox.append('<div class="system_error">Connection Interrupted - [Error#' + e.code + '] ' + e.reason + '</div>');
};

//Message send button
$('#send-message').click(function () {
	send_message();
});

//User hits enter key 
$("#message").on("keydown", function (event) {
	if (event.which == 13) {
		send_message();
	}
});
//User typing
$("#message").on("keypress", function (event) {
	if (event.which !== 13)
		send_notification('typing','Typing...');
});

var notifications = [], isTyping = false;

//Send message
function send_message() {
	var message_input = $('#message'); //user message text
	var name_input = $('#name'); //user name

	if (message_input.val() == "") { //empty name?
		alert("Enter your Name please!");
		return;
	}
	if (message_input.val() == "") { //emtpy message?
		alert("Enter Some message Please!");
		return;
	}
	
	isTyping = false;

	//prepare json data
	var msg = {
		message: message_input.val(),
		name: name_input.val(),
		color: colors[color_pick]
	};
	//convert and send data to server
	websocket.send(JSON.stringify(msg));
	message_input.val(''); //reset message input
}

//Send message
function send_notification(type, msg) {
	var name_input = $('#name'); //user name
	notifications.push(type);
	//prepare json data
	var msg = {
		notification: type,
		message: msg,
		name: name_input.val(),
		color: colors[color_pick]
	};
	if(!isTyping){
		isTyping = true;
		//convert and send data to server
		websocket.send(JSON.stringify(msg));
	}
}

I've tried that but it's not working.
