Padraic Brady has posted about a part of his PHPSpec library, the domain specific language.

PHPSpec implements a domain specific language (DSL) in PHP for specifying the behaviour of functional units such as methods and objects. The purpose of a DSL was to move away from the xUnit style declaration of tests towards a specification language centred on describing behaviour.

He illustrates with a bowling example - described with a sample class (with a itShouldScore0ForGutterGame test) and how to use it to fit his proposal:

My proposal therefore is to re-implement the current programming language DSL as a specification language - i.e. a new (extremely limited and narrow!) language capable of being parsed by PHPSpec into its PHP equivalent. [...] Using a specification DSL, we can simply ignore the existence of classes in PHP (well, the pretense is nice). Instead the DSL would incorporate a syntax for denoting shared behaviours.

Richard Heyes has thrown together some code for a simple thing that he's seen developers request over and over again - moving to/reading from a specific line in a file.

After reading something on the php-general list I decided that a) I'm bored, and b) I'll write something which handles it. So here it is.

His code is simple - looping through the lines of the file until it locates your desired target (with some error checking along the way). Plus, if it's already fetched, it keeps it in a cached array for future retrieval.
