Greetings, friends. I want to share a useful site with cheat sheets for PHP developers. These cheat sheets can be useful to find out the differences in operations for different versions of PHP. Also, to refresh your knowledge before a job interview. The site provides three cheat sheets by category: variable comparison, arithmetic operations, and variable checking.
This section presents the results of a comparison of the values of different types in PHP.
In this section you can see the result of arithmetic operations on values of different types in PHP.
This section shows the result of checking variables and typecasting on values of different types in PHP.
Since you've made it this far, sharing this article would be highly appreciated!
