list of the most popular WordPress functions. And it really is so - after all, I assembled here> 150 plug-ins and compared the functions they use with existing wordpress functions. See all the plugins used in the list-of-plugins.txt file.
All functions found at least once, look in the file all-functions-list.txt
So: at the entrance we have WordPress v4.9.1 (623 php file, 330 000 lines of code), the folder plugins and themes are empty.
and I will function from it to compare with the used functions of 152 plug-ins. There are 15423 php files (3 599 426 lines of code, 117 megabytes).
