If you just want the markup text of the WikiPage and you're running
from pmwiki.php, then the easy way is:

    $page = ReadPage('Group.WikiPage');
    $text = $page['text'];

Otherwise, there are other options for reading the file:

1.  You could duplicate the ReadPage script into your own PHP script.
2.  You can use PmWiki's ?action=source action to retrieve the markup text
3.  You can use the following Unix shell command:
      grep '^text=' wiki.d/Group.WikiPage | tr "\262" "\012"
4.  You can do the equivalent of the Unix shell command in PHP:
      $text_array = preg_grep('/^text=/',file('wiki.d/Group.WikiPage'));
      $text = str_replace("\262","\n",$text_array[0]);

If you're wanting the rendered output of the page (i.e., after it's been
converted to HTML):

1.  If you need the HTML from some script called by pmwiki.php, then
    maybe I can fix PrintText() to return a string.
2.  Alternately, you can make your own calls to PrintText() or PrintWikiPage()
    and surround the calls with ob_start/ob_get_contents.
3.  From outside of PHP, you can create a minimal skin template and then call
    pmwiki.php to render the page using the minimal skin.  I.e., create
    a minskin.tmpl file that contains nothing but <!--PrintText-->, then
    call PmWiki with that skin 
    (http://localhost/pmwiki.php/Main/HomePage?skin=minskin).

Hope this helps?
