Thanks - I will give it a try during the week.
I am trying to find a way to get the value of a page-property pair
without having to loop through all properties on a page only to get
the value of one property.
This is to streamline my customized semantic search results. One of
the bottlenecks is the performance hit from accessing properties for
each page in the list of matches from the search. I am trying to
reduce that hit to the absolute minimal number of property I need from
each page.
I managed to reduce the performance hit to 5 to 8 seconds per
search... which is ok as long as it is under 10 seconds... but I would
feel better about it if I could reduce it down to under 5 seconds per
search.

Yes, you can use the API. If you go to Special:Ask, recreate the
query and select "CSV export" as the format, then hit "Find
results", you should get a URL for the CSV export you need. You then
just need to have the PHP retrieve and parse that URL; you can see
the getCSVData() function in the External Data extension for how to
do that (though your code can probably be simpler).

Actually, I thought about a way that could work, except I still have
to find an example in PHP.
In case someone already knows the answer, how would I go about
getting the results of a #show or #ask query in PHP ?
Something like :
$propertyValuesArray = GetQueryResults("{{#show:Some page|?Some
property}}")
Is this possible with the SMW API ?

Subject: [SMW-devel] How about retrieving a single triple ?
Related to a recent question about retrieving all triples on a page
- is there a quick way to retrieve a single triple on a page ?
More precisely - If I have a page name and a property name, is there
a direct way to get the values for that pair (page, property name)
without having to declare the supporting structures such as :
$page = SMWDataValueFactory::newTypeIDValue( '_wpg', $title-
>getFullText());
$semdata = smwfGetStore()->getSemanticData($page-
>getTitle() );
