php - does fsockopen only allow certain servers? -


That's why I recently made a goal to contact Hostgator about a previous plugin that I did not have "online" or " Offline "depends on the server's status

Now, here's the problem.

The hostgator was disabled and after bothering them, I enabled it. But not all server ips and ports work with it?

For example: 

  & lt ;? Php $ ip = "play.magicacraft.net"; $ Port = "25567"; $ Online = @fsockopen ($ ip, $ port, $ errno, $ errstr, 200); If ($ online> = 200) {echo & lt; A href = "#" class = "MPSververOnline" & gt; Online & lt; / A & gt; '; } Else {echo '& lt; A href = "#" class = "MPServer_offline" & gt; Offline & lt; / A & gt; '; }? & Gt;   
 Gives me this as online.  
 If I use any other IP and IP server like:    $ port = 72.20 .55.85 "; $ ip =" 25570 ";   
 It never says offline that it is online  
 Is it a fault on my end or on them? Sites such as can use this information and I can not.  
 Thank you for your time   
 
 
 Did you check to make sure Is not blocked by port firewall / iptables ?  
 Try the default example to see if this port block may be a problem by using port 80

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
