    <p>I am using the following class for my application and it is working absolutely fine:</p> <pre><code>class Telnet { /* (c) thies@thieso.net */ var $sock = null; function telnet($host, $port) { $this-&gt;sock = fsockopen($host, $port); socket_set_timeout($this-&gt;sock, 2, 0); } function close() { if ($this-&gt;sock) fclose($this-&gt;sock); $this-&gt;sock = null; return "Disconnected"; } function write($buffer) { $buffer = str_replace(chr(255), chr(255) . chr(255), $buffer); fwrite($this-&gt;sock, $buffer); } function getc() { return fgetc($this-&gt;sock); } function read_till($what) { $buf = ''; while (1) { $IAC = chr(255); $DONT = chr(254); $DO = chr(253); $WONT = chr(252); $WILL = chr(251); $theNULL = chr(0); $c = $this-&gt;getc(); if ($c === false) return nl2br($buf); if ($c == $theNULL) { continue; } if ($c == "\021") { continue; } if ($c != $IAC) { $buf .= $c; if ($what == (substr($buf, strlen($buf) - strlen($what)))) { return nl2br($buf); } else { continue; } } $c = $this-&gt;getc(); if ($c == $IAC) { $buf .= $c; } else if (($c == $DO) || ($c == $DONT)) { $opt = $this-&gt;getc(); //echo "we wont ".ord($opt)."\n"; fwrite($this-&gt;sock, $IAC . $WONT . $opt); } elseif (($c == $WILL) || ($c == $WONT)) { $opt = $this-&gt;getc(); //echo "we dont ".ord($opt)."\n"; fwrite($this-&gt;sock, $IAC . $DONT . $opt); } else { //echo "where are we? c=".ord($c)."\n"; } } } } </code></pre> <p>then i added another page for a CLI (which will interact through jquery with this class):</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Simple CLI&lt;/title&gt; &lt;script src="./../../script/jquery-1.7.1.min.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div&gt; User:&lt;input id="username" type="text" /&gt;Password:&lt;input id="password" type="text" /&gt; &lt;input id="connect" type="button" value="Connect" /&gt; &lt;div id="out"&gt;Welcome: Type 'connect' to connect to the terminal server.&lt;br /&gt;&lt;/div&gt; &lt;input id="in" type="text" /&gt; &lt;input id="disconnect" type="button" value="Disconnect" /&gt; &lt;/div&gt; &lt;script type="text/javascript"&gt; $('#connect').click(function(e){ var user = $('#username').val(); var pass = $('#password').val(); if( user != "" &amp;&amp; pass != "" ){ $.post('abc.php', {cmd:"connect",user:user,pass:pass}, function(data) { $('#out').append(data); }); } }); $('#disconnect').click(function(e){ $.post('abc.php', {cmd:"disconnect"}, function(data) { $('#out').append(data); }); }); $('#in').keyup(function(e) { if (e.which !== 13) return; var cmd = { cmd: $(this).val() }; $(this).val(''); $.post('abc.php', cmd, function(data) { $('#out').append(data); }); }); &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>the class is used by:</p> <pre><code>if($_POST['cmd']){ $command = $_POST['cmd']; switch($command){ case 'connect': $output = ''; if( !empty($_POST['user']) &amp;&amp; !empty($_POST['pass']) ){ $tn = new telnet("127.0.0.1", 23); $output = $tn-&gt;read_till("ogin:"); $tn-&gt;write($_POST['user'] . "\r\n"); $output .= $tn-&gt;read_till("word: "); $tn-&gt;write($_POST['pass'] . "\r\n"); $output .= $tn-&gt;read_till(":&gt; "); echo $output; } break; case 'disconnect': echo $tn-&gt;close(); break; default: $tn-&gt;write($command."\r\n"); echo $tn-&gt;read_till(":&gt; "); break; } } </code></pre> <p>the question is that how and where can i save the class object, so that whenever i call a class object through jquery, it should have the same object and not that each command will first open a new connection with the telnet server.</p>

    1. CONot sure you can save the class instance somewhere but what you can do is try to open a persistent connection using `pfsockopen` http://www.php.net/manual/en/function.pfsockopen.php

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
