Demonstrates how functional composition with pipes can create regex patterns with less code and fewer side effects compared to object-oriented builder patterns. Shows practical examples of converting C# regex builder methods into PHP pipe operator functions, including character patterns, quantifiers, lookaheads, and groups. Argues that pipe operators offer simpler testing, easier extensibility, and language-level regex building, though acknowledges the trade-off of less intuitive naming compared to fluent APIs. ## Full article daily.dev links to this article rather than hosting it.
