About Course

Having captured more than 78% of the web development languages market, PHP is a fast, popular, and well supported web development language. PHP 8 has been long anticipated, but the wait is just about over! This information-packed intensive core PHP course is designed for PHP developers with a knowledge of PHP 5.x or 7.x. Learn about all the great new features in PHP 8 with a focus on migration from PHP 7 to PHP 8. Get a head start and leave the rest of the crowd behind.

Detailed Course Outline

Core OOP Coding Differences

There are two words that causes any developer to start looking nervously over his or her shoulder: _backwards incompatible_. Thus was born the phrase _BC Breaks_ meaning code that breaks due to backwards compatibility issues. In this unit we cover core PHP 8 language coding differences you must learn about in order avoid BC breaks.

This unit includes the following topics:

Procedural Programming Differences

Prior to May 2000, when PHP 4 was officially released, all PHP programming used what is now referred to as _procedural_ coding style. Procedural programming is distinctive in its extensive use of libraries of _functions_ rather then OOP classes. In this unit we focus on PHP 8 changes to procedural programming.

This unit includes the following topics:

Procedural Programming Differences

Differences in String Handling

Non-Well-Formed Numeric Strings

Extension Gotchas

In addition to changes to the PHP core, there have been significant changes to a number of PHP extensions as well. In this unit we identify critical changes in key extensions and things you need to watch out for to avoid BC breaks.

Error Handling Improvements

Error handling has been strengthened in PHP 8. As many of you have observed during the transition from PHP 5 to PHP 7, error handling was improved. With each successive release of PHP 7.x, you also observed that bad programming practices are slowly being restricted. PHP 8 goes one step further, as explained in this unit.

This unit includes the following topics:

Error Handling Improvements

Warnings Promoted to Fatal Errors!

Warnings Promoted: Array

Warnings Promoted: String

Undefined Constants Now Fatal Errors

Notices Promoted to Warnings!

Error Level Defaults Changed

Use of Parent

No Longer @Silent

Inheritance and Method Signatures

Error Related INI Directives

Compile Time Warning Changes

Clean Shutdown

Non Capturing Catches

Going, Going … Not Quite Gone

Using classes, methods, functions, etc. on the _deprecated_ list are not going to break your code, however it’s an indication that at some point in the near future these constructs will be removed from the language. Accordingly, it’s important for PHP developers to at least be aware of the more important deprecated functionality in PHP 8.

This unit includes the following topics:

Going, Going … Not Quite Gone

Core Deprecations

Deprecations: Enchant

Deprecations: Reflection
