[ome-users] Connecting to the image server through PHP.

Sat Feb 23 02:02:46 GMT 2008

Dear Curtis:

I thank you so much for the inputs. Actually, I was able to read in the images using PHP. First, I tried to execute the command line interface available in OME (curl) using 'shell_exec()', 'system()' and 'exec()' system calls available in PHP. I also tried 'wget'. Unfortunately none of them worked. There is a curl library for PHP. I didn't try that out. But, the 'http' interface in OME was helpful. I now directly point to my image source through the 'http' directive which creates the image and displays it on the browser. I am still not sure how one can save the images to the system (using PHP script) to retrieve it back (either to the browser or as a file).

Thanks.
Kasthuri.

P.S: In retrospect, I think the ./OMEIS executable should be helpful for creating and saving the image file through PHP - need to try that out...

 Hi Kasthuri,

 Can anyone help me by letting me know how one can connect to the OME Image Server (OMEIS) through PHP? I am trying to write a script that can pull an image from OMEIS and display it on the browser. I tired reading the image server documentation but couldn't exactly locate the information on how this could be done.

If your PHP code is being served from the same machine as the OME installation, you might be able to get away with a PHP-Perl communication layer of some kind (e.g., http://devzone.zend.com/node/view/id/1712).

Otherwise, the OME server remoting infrastructure uses XML-RPC to communicate. You could use an XML-RPC library for PHP -- googling for "php xml-rpc" I immediately found http://phpxmlrpc.sourceforge.net/ as well as http://us3.php.net/xmlrpc, which indicates that perhaps newer versions of PHP have some built-in XML-RPC capability.

There is a client layer called OME-Java that demonstrates this connectivity for Java, but unfortunately no one to my knowledge has coded such a thing in PHP.

There has also been some discussion on the ome-devel mailing list about XML-RPC (http://lists.openmicroscopy.org.uk/pipermail/ome-devel/2004-July/000049.html, http://lists.openmicroscopy.org.uk/pipermail/ome-devel/2005-October/000543.html).
