[SPT/CWIS] SPT and PHP5

[Jhonatan Tirado]

Well, I think the poster you're talking about is the mine.
In fact, I succeeded in porting to PHP5, just using a cast operator.
If you have any question, maybe I can help.
And you can see the site running SPT/CWIS and PHP5 at

http://peru.campusvirtualsp.org/repositorio/SPT--Home.php

Apache/2.0.55
mysql  Ver 14.12 Distrib 5.0.24a
Ubuntu Server Edition 6.10

And the poster is the following:

Hi.
Recently, I had the following problem:

*Warning*: array_merge() [
function.array-merge<http://peru.campusvirtualsp.org/repositorio/function.array-merge>]:
Argument #1 is not an array in */var/www/repositorio/include/SPT--
GlobalSearchEngine.php * on line *91*

*Warning*: array_merge()
[function.array-merge<http://peru.campusvirtualsp.org/repositorio/function.array-merge>]:
Argument #2 is not an array in */var/www/repositorio/include/SPT--
GlobalSearchEngine.php * on line *91*

*Warning*: usort()
[function.usort<http://peru.campusvirtualsp.org/repositorio/function.usort>]:
The argument should be an array in */var/www/repositorio/include/SPT--
GlobalSearchEngine.php* on line *100*

*Warning*: array_slice()
[function.array-slice<http://peru.campusvirtualsp.org/repositorio/function.array-slice>]:
The first argument should be an array in */var/www/repositorio/include/SPT--
GlobalSearchEngine.php * on line *106
*
It happened while doing a global search to another friend sites.
Specifically, the following code gave the error:

function PerformSearch($SetSpec, $StartingResult, $NumberOfResults)
    {
        # for each global search site
        $DB =& new SPTDatabase();
        $DB->Query("SELECT * FROM GlobalSearchSites");
        $SearchResults = array();
        while ($SiteInfo = $DB->FetchRow())
        {
            # retrieve results from site
            $SiteSearchResults = $this->SearchSite($SiteInfo, $SetSpec);

            # add results to result list
            $SearchResults = array_merge($SearchResults,
$SiteSearchResults); **error
        }

        # sort the results in descending order by search score
        function SearchScoreCmp($ResultA, $ResultB)
        {
            return ($ResultA["Search Score"] == $ResultB["Search Score"]) ?
0
                    : (($ResultA["Search Score"] < $ResultB["Search Score"])
? 1 : -1);
        }
        usort($SearchResults, "SearchScoreCmp");

        # save number of results found
        $this->NumberOfResultsAvailable = count($SearchResults);

        # trim result list to match range requested by caller
        $SearchResults = array_slice($SearchResults, $StartingResult,
$NumberOfResults);

        # return search results to caller
        return $SearchResults;
    }

It happens when there are not results matching the search criteria. In that
case, $SiteSearchResults would be null. With PHP 4.x, no problem, it
converts null to array on the fly. But PHP 5.x needs to have it explicit.
So, the only thing you have to do is to add (array), to convert the variable
to array on the fly, cause in other way, PHP wouldn't understand the
syntaxis and give you the error:
 $SearchResults = array_merge($SearchResults, (array) $SiteSearchResults);

So, if any of you wants to upgrade to PHP 5.x, it's OK. The only thing you
have to do is to add that word (array()) and you're done.

Greetings!

PD: I'm also using MySQL 5.x, Apache 2.x and Ubuntu Server Edition 6.10
