Parsing and data processing in PHP

This article will discuss methods for processing data in PHP, but it is not finished yet.

So temporarily just a quick sketch of the possibilities:

• Crawl character by character is a very old method that makes the code messy, but all other methods do it internally.
• Explode, splitting a string by a delimiter
• Regular expressions are the best way to handle simple strings
• Tokenizer, splits a complex string into pieces (tokens) according to regular expressions, for example this is how PHP is processed
