The structure looks very usable.  We'll probably want some way to pass
options.  But, that is a minor issue at this point.

A PHP interface might look like swishe_open(), swishe_search(),
swishe_next(), swishe_close().  PHP shares most of the PERL's language
constructs.  The rest of the example code would be nearly identical to
PERL.

PHP EXAMPLE:

#!/usr/local/bin/php

$properties="";   # No properties
#$properties="prop1 prop2 prop3"; 
$handle=swishe_open("../src/index.swish");

$structure=1;       # Related to -t option of swish-e
$words='test';   # search string

$num_results=swishe_search($handle,$words,$structure,$properties);

print "Search Results: $num_results\n";
while(list($rank,$filename,$title,$size,$prop1,$prop2,$prop3)=swishe_next($handle))
{
        print "$rank $filename \"$title\" $size \"$prop1\" \"$prop2\" 
\"$prop3\"\n";
}

:ELPMAXE PHP ;-)

Dirk Nerinckx did some DLL work for Windows in a very early port.  In
fact, we both were using SWISH-E as ISAPI modules under MS-IIS at the
time (albeit unreliably).  

Dirk replaced all exit() calls with a C++ throw call in his code. 
Something similar could probably be done which would be more portable.
