\nInstall from pecl<\/p>\n

teddy@teddy:~$ sudo pecl install swoole\r\n[sudo] password for teddy: \r\nWARNING: channel \"pecl.php.net\" has updated its protocols, use \"pecl channel-update pecl.php.net\" to update\r\ndownloading swoole-4.4.5.tgz ...\r\nStarting to download swoole-4.4.5.tgz (1,426,083 bytes)\r\n.........................................................................................................................................................................................................................................................................................done: 1,426,083 bytes\r\n391 source files, building\r\nrunning: phpize\r\nConfiguring for:\r\nPHP Api Version:         20170718\r\nZend Module Api No:      20170718\r\nZend Extension Api No:   320170718\r\nenable sockets supports?

Then include the extension “extension=swoole.so” in php.ini file. For php-fpm, the php.ini file in “\/etc\/php\/7.2\/fpm\/php.ini”<\/p>\n
sudo gedit \/etc\/php\/7.2\/fpm\/php.ini<\/pre>\n
then add this new line:<\/p>\n
...\r\nextension=swoole.so\r\n...<\/pre>\n
Save then restart php7.2-fpm service<\/p>\n
sudo service php7.2-fpm restart<\/pre>\n
look it up phpinfo() result. It should show like this:\"\"<\/a>Pls do the same thing for php cli. the php.ini file for php cli in “\/etc\/php\/7.2\/cli\/php.ini”. So edit the file and add a new line for the extension “extension=swoole.so”. Check the extension is loaded on the terminal:<\/p>\n
teddy@teddy:~$ php -m | grep swoole\r\nswoole<\/pre>\n
Note: I tried to do this via terminal<\/p>\n
php -i | grep php.ini                      # check the php.ini file location\r\nsudo echo \"extension=swoole.so\" > php.ini  # add the extension=swoole.so to the end of php.ini\r\nphp -m | grep swoole                       # check if the swoole extension has been enabled<\/pre>\n
But it didn’t work. The extension is not loaded so I put it manually in the php.ini for cli.
\nNOTE: IT NEED TO DISABLE ‘xdebug’ EXTENSION. CHECK IF xdebug IS ACTIVE\/ENABLED:<\/p>\n
teddy@teddy:~$ php -i | grep xdebug\r\n\/etc\/php\/7.2\/cli\/conf.d\/20-xdebug.ini,\r\nextension 'xdebug' detected\r\nxdebug\r\nxdebug support => enabled\r\n...<\/pre>\n
IF IT IS ENABLED, THEN MODIFY ‘\/etc\/php\/7.2\/cli\/conf.d\/20-xdebug.ini’ FILE TO DISABLE xdebug BY ADDING ‘;’ IN FRONT OF THE LINE LIKE THIS:<\/p>\n
;zend_extension=xdebug.so<\/pre>\n
IF xdebug IS ENABLED WHEN THE SERVER IS RUNNING, IT’D SPIT THIS WARNING:<\/p>\n
teddy@teddy:~\/Documents\/works\/swoole$ php server.php \r\nPHP Warning:  Swoole\\Server::start(): Using Xdebug in coroutines is extremely dangerous, please notice that it may lead to coredump! in \/home\/teddy\/Documents\/works\/swoole\/server.php on line 21\r\nPHP Stack trace:\r\nPHP   1. {main}() \/home\/teddy\/Documents\/works\/swoole\/server.php:0\r\nPHP   2.

TEST SWOOLE
\nref: https:\/\/github.com\/swoole\/swoole-docs\/blob\/master\/get-started\/examples\/tcp_server.md
\nCreate a new file server.php<\/p>\n
<?php\r\n\/\/ Create the server object and listen 127.0.0.1:9501\r\n$server = new swoole_server(\"127.0.0.1\", 9501);\r\n\r\n\/\/ Register the function for the event `connect`\r\n$server->on('connect', function($server, $fd){\r\n    echo \"Client : Connect.\\n\";\r\n});\r\n\r\n\/\/ Register the function for the event `receive`\r\n$server->on('receive', function($server, $fd, $from_id, $data){\r\n    $server->send($fd, \"Server: \" . $data);\r\n});\r\n\r\n\/\/ Register the function for the event `close`\r\n$server->on('close', function($server, $fd){\r\n    echo \"Client: {$fd} close.\\n\";\r\n});\r\n\r\n\/\/ Start the server\r\n$server->start();<\/pre>\n
Run the php in a terminal<\/p>\n
teddy@teddy:~\/Documents\/works\/swoole$ php server.php<\/pre>\n
then open another terminal and type ‘telnet 127.0.0.1 9501’<\/p>\n
teddy@teddy:~$ telnet 127.0.0.1 9501\r\nTrying 127.0.0.1...\r\nConnected to 127.0.0.1.\r\nEscape character is '^]'.<\/pre>\n
The first terminal would print ‘Client : Connect’<\/p>\n
teddy@teddy:~\/Documents\/works\/swoole$ php server.php \r\nClient : Connect.<\/pre>\n
You can connect with another new terminal.
\nTo close the connection in the second terminal, press Ctrl + ] then type close in telnet><\/p>\n
teddy@teddy:~$ telnet 127.0.0.1 9501\r\nTrying 127.0.0.1...\r\nConnected to 127.0.0.1.\r\nEscape character is '^]'.\r\n\r\nServer: \r\nhello\r\nServer: hello\r\n^]\r\ntelnet> close\r\nConnection closed.<\/pre>\n
The first terminal would give response like this:<\/p>\n
teddy@teddy:~\/Documents\/works\/swoole$ php server.php \r\nClient : Connect.\r\nClient : Connect.\r\nClient: 1 close.<\/pre>\n
Create web server
\nref: https:\/\/github.com\/swoole\/swoole-docs\/blob\/master\/get-started\/examples\/http_server.md
\ncreate a new file ‘http_server.php’<\/p>\n
<?php\r\n\/\/ Create the http server object \r\n$http_server = new swoole_http_server(\"127.0.0.1\", 9503);\r\n\r\n\/\/ Register the event of request\r\n$http_server->on('request', function($request, $response){\r\n    var_dump($request->get, $request->post);\r\n    $response->header(\"Content-Type\", \"text\/html;charset=utf-8\");\r\n    $response->end(\"<h1>Hello Swoole \" . rand(1000, 9999) . \"<\/h1>\");\r\n});\r\n\r\n\/\/ Start the server\r\n$http_server->start();<\/pre>\n
then run the server via terminal<\/p>\n
teddy@teddy:~\/Documents\/works\/swoole$ php http_server.php<\/pre>\n
Open it via web browser: http:\/\/127.0.0.1:9503\/
\nIt should show this message:<\/p>\n
