Im new to regex but not new to the php language. Im looking for a regex pattern that will capture the number of results from "ANY" of the following snippets... Also the content being searched is basically ALL the html from a google search so it needs to be precise and character limited so it doesnt pick up "of about" or "</b>" somewhere later in the content...

CODE:
preg_match($regexpattern,$content,$result);
print $result[1];

EXAMPLES:

CONTENT: Results <b>1</b> - <b>5</b> of <b>5</b> for
RESULT SHOULD BE: 5

CONTENT: Results <b>1</b> - <b>10</b> of about <b>15,000,000</b> for
RESULT SHOULD BE: 15000000

CONTENT: Results <b>1</b> - <b>8</b> of about <b>12,000</b> for
RESULT SHOULD BE: 12000

CONTENT: Results <b>1</b> - <b>8</b> of <b>987</b> for
RESULT SHOULD BE: 987

Try something like the following.  Let me know if you have questions or your sample data is more complicated.
Results <b>[\d,.]*</b>\s*-\s*<b>[\d,.]*</b>\s*of[^<]*<b>([\d.,]*)</b> for

preg_match('|of[^<]+<b>([\d,\s]+)</b> for|',$content,$result);
$result[1] = preg_replace('/\D/', '',$result[1]);
print $result[1];

just so both of you guys know...  </b> has to be escaped such as <\/b>
obrienslalom's pattern worked great i ended up tweaking it a bit to the following...

preg_match('/Results 1\s*-\s*[\d]{1,2}\s*of[A-Za-z ]*([\d.,]{1,22}) for/si',$content,$results);
to simplify things I did a str_replace on $content to remove <b> tags before using the pattern above.
