I'd take the results of file() and then
walk through the array looking for the lines for the
various fruit you're concerned with. Then I'd grab the next
two lines and process them, with something like:
$line = "<td align=left>.46</td>";
ereg('^<td align=(left|right)>([^<]+)</td>',$line,$m);
echo $m[1] . "\n";
echo $m[2] . "\n";
IMHO, it's bad to do this kind of thing because any change in
the content means a breakage of your processing code. I
think that using something like XML or the DOM may be a
better approach. Individuals with knowledge in this area can
speak more to this idea.
Good luck.
