Many examples found throughout this book involve embedding MySQL queries directly into a PHP script. Indeed, for smaller applications this is fine; however, as application complexity and size increase, you’ll probably want to seek out more effective ways to manage your SQL code. Notably, some queries will reach a level of complexity that will require you to incorporate a certain degree of logic into the query in order to achieve the desired result. Consider a situation in which you deploy two applications, one targeting the Web and another targeting the iPhone, both of which use the same MySQL database and perform many of the same tasks. If a query changed, you’d need to make modifications wherever that query appeared not in one application but in two!
