MySQL + PHP - Search Engine question!
Hi All - I'm building a search engine and what I would like to do is run a search and get the number of results, but still use the LIMIT command so I am not returning a ton of rows all at once. Is this the best way to go about searching? Thanks, Matt Babineau Criticalcode w: http://www.criticalcode.com p: 858.733.0160 e: [EMAIL PROTECTED]
Re: Mysql + PHP - Search
I just answered my own question actually! - snip from php.net - MySQL 4.0 supports a fabulous new feature that allows you to get the number of rows that would have been returned if the query did not have a LIMIT clause. To use it, you need to add SQL_CALC_FOUND_ROWS to the query, e.g. $sql = Select SQL_CALC_FOUND_ROWS * from table where state='CA' limit 50; $result = mysql_query($sql); $sql = Select FOUND_ROWS(); $count_result = mysql_query($sql); You now have the total number of rows in table that match the criteria. This is great for knowing the total number of records when browsing through a list. -- Matt Babineau Criticalcode w: http://www.criticalcode.com p: 858.733.0160 e: [EMAIL PROTECTED]
