Python to PHP Equivalents

This article provides a list of common Python 2 and Python 3 commands and their PHP equivalents. While the languages have different syntax and structure, it is possible to find similar functionality in both. Keep in mind that this list is not exhaustive, and there may be other ways to achieve the same functionality in each language.
