15 PHP regular expressions for web developers
Regular expressions are a very useful tool for developers. They allow to find, identify or replace text, words or any kind of characters. In this article, I have compiled 15+ extremely useful regular expressions that any web developer should have in his toolkit.
Getting started with regular expressions
For many beginners, regular expressions seems to be hard to learn and use. In fact, they're far less hard than you may think. Before we dive deep inside regexp with useful and reusable codes, let's quickly see the basics:
Regular expressions syntax
| Regular Expression | Will match... |
| foo | The string "foo" |
| ^foo | "foo" at the start of a string |
| foo$ | "foo" at the end of a string |
| ^foo$ | "foo" when it is alone on a string |
| [abc] | a, b, or c |
| [a-z] | Any lowercase letter |
| [^A-Z] | Any character that is not a uppercase letter |
| (gif|jpg) | Matches either "gif" or "jpeg" |
| [a-z]+ | One or more lowercase letters |
| [0-9.-] | Аny number, dot, or minus sign |
| ^[a-zA-Z0-9_]{1,}$ | Any word of at least one letter, number or _ |
| ([wx])([yz]) | wy, wz, xy, or xz |
| [^A-Za-z0-9] | Any symbol (not a number or a letter) |
| ([A-Z]{3}|[0-9]{4}) | Matches three letters or four numbers |
