Q:

How could I make simple row selections from a database with Boole operations?

I have a search engine. I would like to select rows from my table with boolean operations when a user types in a search term. Should I use 
explode(); 

or maybe
split();

? 
I would like to use the "OR" operator for selecting the rows.

A:

PHP's split() function is deprecated. Don't use it. Instead, try explode(), str_split(), or preg_split().
If you're using a SQL database, such as MySQL or PostgreSQL, test with UNION and UNION ALL instead of OR.  You might be surprised.
