Summary: PHP 8’s Deprecated or Removed Functionality

Key takeaways

• We learned about deprecated and removed PHP functionality. First, we dealt with core functionality that has been removed. The rationale for the change was explained, and we learned that the main reason for removing the functionality is not only to move toward code that follows best practices but to use PHP 8 functionality that is faster and more efficient.

• Next, we learned about deprecated functionality. The key theme was to highlight how the deprecated functions, classes, and methods lead to bad practices and bug-ridden code.
