How do i join/combine/merge PHP variable with a text?

Hello,

i have this PHP code:

this line will cause this command be executed: /usr/sbin/vzctl set 1234 --hostname lkmjfkgkl --save

And i need the command to be different: /usr/sbin/vzctl set 1234 --hostname lkmjfkgkl.host.name --save

So here i am looking on how to modify above mentioned line of php code.

Please how can i join $this->main->hostname with .host.name ?

I tried:

but do not think it works

Please which code to use so i merge above mentioned variable with text ".host.name" so it is merged without any spaces?

 

If I am understanding correctly, you want to append 'host.name' string on to a variable?

If so, you would use a full stop/dot

e.g.

$this->main->hostname . "host.name"

Code (markup):

Hope this helps

 

Like this:

lxshell_return("/usr/sbin/vzctl", "set", $this->main->vpsid, "--hostname", $this->main->hostname.".host.name", "--save");

 

Thank You both. This one also works:
lxshell_return("/usr/sbin/vzctl", "set", $this->main->vpsid, "--hostname", "{$this->main->hostname}.host.name", "--save");
