PHP script issue

Hi there experts!

Got a problem regarding my virtual server which is running CentOS 5.5 with webmin, all modules such as httpd, mysql, mysql-server all up-to-date.

I have a php script that interfaces with a virtual world called Second Life, the purpose of this script is to allow the webserver to interface with the secondlife script, which is set to listen for specific commands.

After trying multiple times, running a whole different distro of linux thinking that was the issue, i've came to a complete stop.

This php script works with a friends webserver, although running plesk and hosted for him by a hosting provider, i'm completely self hosted, his script works without a problem, yet when i attempt to do the same, the php page hangs for a long while (not crash style) then EVENTUALLY refreshes, like it completed the request...yet it hasn't.

Looking at the error_log i find nothing of issue, although my knowledge is rather limited so having alot of new eyes looking this over might show me the issue, and possible resolution.

Below is how i operate the script and what results i expect to have it achieve:

Webserver provides php page with a list of objects in second life, that have contacted the webserver with its, unique identifer masks, world location, time it last contacted etc.

I select one and check a box labelled set text and enter "Hello World", then hit send, which SHOULD have floating text above the object in secondlife with "Hello World"

Yet instead it hangs...then does nothing, my friends webserver using the same script, however does this and the changes becomes apparant immediately.

Here is what the URL looks like: (Friends webserver using plesk, has kindly provided phpinfo, though looks greek to me for the most part)

http://paintballpalmer.com/sls1/manageserver.php?xml=70b92dc6-0c4d-630e-b32f-c084e7c9adec&slcmd=st&settext=Hello+World+411&cmd=Send

^ - this would change the selected objects floating text, however when i use that on my webserver, changing the domain name to an IP (no domain name hosting, just IP) the hang occurs.

Not sure what else to provide, however if you require anything else then i will gladly give the information, there may be some delay between responses due to work related matters, yet i do check in regularly so do not think i'm...how to put it....not serious about this or something, because i very much am.

Hope to hear from you all soon experts!

P.S - to further the possible understanding to resolution, i have provided the code for the servers.php of my server to see if there is any obvious issues i may have overlooked.
