Reguläre Ausdrücke (einfach) erklärt
Harry Fuecks startet eine Serie zu Regulären Ausdrücken: The Joy of Regular Expressions
So going to take a crack at Yet Another Regular Expressions tutorial, with a focus on doing (in PHP) while slowly introducing you to regexp (shorthand for regular expression) syntax. This is going to span a few blog posts (…) and get progressively “more interesting”—not all for beginners but if you keep up, hopefully you’ll be able to grasp it.
Schön anschaulich das Ganze!
