Quick way to do data lookup in PHP

- by Ghostrider

I have a data table with 600,000 records that is around 25 megabytes large. It is indexed by a 4 byte key. Is there a way to find a row in such dataset quickly with PHP without resorting to MySQL? The website in question is mostly static with minor PHP code and no database dependencies and therefore fast. I would like to add this data without having to use MySQL if possible. In C++ I would memory map the file and do a binary search in it. Is there a way to do something similar in PHP?

Getting single value from a single row with Mysql/PHP

- by Ghostrider

Often I just need to get a single value from MySQL that I know exists there. I use the following construct: $result = end(mysql_fetch_array(mysql_query('SELECT FOUND_ROWS()', $db))); Is there a proper single function in PHP that would do this?
