I faced a challenge several months ago where I had to query a large, complex data result from MySQL. I &ldquo;paged&rdquo; through the results using LIMIT and OFFSET. However, I wanted to know the total number of rows w/o the LIMIT. The previous coder accomplished this by a query before appending the LIMIT statement at the end. This turned out to be very inefficient due to MySQL put together the 10000+ rows and sent it to PHP ready to be parsed, only to have the function mysql_num_rows() to be executed on it.</p>
