How to sort text from 2 files?

Question

PHP

There is a text. A file with text is a text file with correctly spelled words - a dictionary. The program reads the text and checks whether the word is in the dictionary or not. All words that are not by default are considered incorrectly spelled and are displayed on the screen as misspelled words.

Answer 1

In fact, you need regular expressions
Read the text into a variable and run it through preg_match_all
I don’t remember if the pregmatch can accept an array as rules, if not, then run the text into the pregmatch for each word with the for loop
