Read the man page: http://www.php.net/manual/en/ref.pcre.php; the problem is
that regular expression patterns should be enclosed with delimeters, e.g.:
|<pattern>|
where the pipes are the delimeters applied to indicate the pattern's start
and end.
If you would change your code into the following:
$arrayTR = "<td>The value in cell 1</td><td>and cell 2</td>";
if (preg_match('|<(\w+)*?>(.*?)</\1>|', $arrayTR, $m)) {
print "Finding the cells...".$m[1]."\n";
}
You will get "Finding the cells...td". When you examin $m with the print_r()
function, you will notice that the string you are expecting will be in the
third nested array within $m ($m[2]).
If you want to match all occurances, use preg_match_all (see
http://www.php.net/preg_match_all for more info).
