Hi Andreas (and others),
Thank you for your assistance.
I have moved past my oracle issues now, but I'm having trouble with Mapserver.
The only error I get is
"Error in getString(): Parsing error near (DD):(line 463)"
I'll attach my code to help, but I'm not sure why I'm having this issue.
Any advice is very welcome.
Thank you.
Jess

Hello Jessica,
I've tested your code successfully on PHP MapScript v5.2.0.

What errors do you get? Something like "[...] Error: ORA-12154:
TNS:could not resolve the connect identifier specified"? Then you
might need to set some environment variables first. For example,
I set ORACLE_HOME, TNS_ADMIN, LC_CTYPE and NLS_LANG.
> The lack of error reporting from

You can execute your script on the command line via "php <scriptname>".
This will display errors as long as error_reporting(E_ALL) or similar
is set:
$ php test.php
Warning: [MapServer Error]: msDrawMap(): Failed to draw layer named
'ASSET'.
in /tmp/foo/test.php on line 53
Warning: [MapServer Error]: msOracleSpatialLayerOpen(): Cannot create
OCI Handlers. Connection failure. Check the connection string. Error:
ORA-12154: TNS:could not resolve the connect identifier specified
.
in /tmp/foo/test.php on line 53
Error in msDrawMap(): Failed to draw layer named 'ASSET'.<br>
