Hi,

I found your script highly useful and awsome.
Could you tell me how could I query in such a way that I get 30 results per page.

Thanks.
Regards,
Nainil Chheda.

Nice modification!  I probably would have just done something like

preg_match("|&lt;Title&gt;(.+)&lt;/Title&gt;|Ui", $contents, $regs );
  $title = $regs[1];

Rather than mucking with all that strpos stuff, but like the PERL folks say "There`s More Than One Way to Do It"  =)

One thing, though, I was looking over the script one problem is the strpos substr method, unlike the preg method, is case sensitive.  Try changing one of the HTML pages it is searching so you have &lt;TITLE&gt;blah&lt;/TITLE&gt; instead of &lt;title&gt;blah&lt;/title&gt;.  I just tried it and it broke.

If you use the preg I posted in the previous comment though everything thing works nicely.  All in all you did a good job  =P
