Hello Mr. McKenzie,
Thanks for the response. I do not see zend optimizer+ on:
http://www.zend.com/en/downloads/
There is a zend optimizer download link, but this is different than zend
optimizer+. My understanding is the former facilitates with the use of
zend gaurd while the latter optimizes the opcode. I want the latter
component.
Where does one obtain the zend optimizer+ component? (I spent the
better part of my saturday trying to find it). I ended up installing
the zend server community edition to see how it configured its own
apache and php installs in the httpd.conf and php.ini as a way to shed
some light on to my understanding.
The zend server is using different libraries then the standard php
install. I could try to mimic the behaviour of the zend server
configuration with my original php configuration; however, I'm a bit
concerned about only grabbing partial components...maybe i don't need to
be so worried. Maybe this plan isn't even possible.
I guess i was expecting to google, 'install zend optimizer+ component'
and find gooooogles of howtos. Because i don't see this, it makes me
wonder if i'm trying to do something i oughta not...
My question boils down to:
How do I extend my current php install to add a component (zend
optimizer+) to my current php install?
Thanks,
dK

I'm really not sure what the + designation is for, they may have changed
the way things work since I last used the optimizer. The Zend Optimizer
used to be a byte code optimizer/cacher that also allowed you to run
Zend Guard encrypted apps that you were authorized to use. Zend Guard
you need to buy and it allows you to encrypt your apps.

Hi,
I need to develop an interface that will, for example, ping IPs from a
remote server. So the php script will be hosted in a server with ssh access
(key) to the remote server.
I can make it work from the console but when I try
$cmd = "ssh remote-server 'ping -c 4 ip'"
exec($cmd, $ouput);
the output is empty.
the same command (with the remote-server and IP changed to the real ones)
works fine from command line.
I've added the key/config in the webserver's user .ssh directory so I am
assuming that that there is something wrong with my setup.
any ideas?

Probably other ways to do it, but this seems to work:
[mich...@archie ~]$ php a.php
259

64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.518 ms

[mich...@archie ~]$ cat a.php
<?php
$stuff = `ssh management 'ping -c 1 192.168.1.1'`;
echo strlen($stuff) . "\n\n$stuff";

following is the code in .htaccess file
ErrorDocument 404 /filenotfound.html
the file filenotfound.html is also in the root directory as the htaccess
file
when i intentionally type a wrong url either if a misspell a file ex=
http://domainname.com/filenam.html or a folder ex =
http://domainname.com/100
to test if this is working filenotfound.html is not being called
any reason why this is happening
also the same thing with wamp on my local computer, i have a htaccess and
also the filenotfound
in d:/wamp/www however when i misspell the ulr of my localhost, i have
noticed in the status bar that the page is being redirected to
http://linkhelp.clients.google.com and i get a 404 from this website, how
can i change this redirection
2.
how do i access the php.ini and httpd.conf file from my cpanel, do i need to
ask my hosting provider to make any changes or can i make these changes
myself
3.
after downloading putty and if i have wamp in d:/wamp/www how do i access
mysql from the command prompt
using putty on my local machine
please advice
thanks.
