PHP Training Class | Learn Online | Live Instructor | Web Courses 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. https://phptraining.net 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: Core OOP Coding Differences Magic Method Changes: Constructor Magic Method Signatures Magic Method Signatures Example Magic Method Changes: Sleep Serialization Differences Custom Serialization Custom Serialization Example Private Method Signatures Private Method Signature Example Static Anyone? Object Properties No Longer Array Keys Anonymous Class Control Stringable Interface Namespace Handling Namespace Handling Considerations Namespace Handling BC Break Trait Handling Refinements Trait Abstract Signature Check Private Abstract Methods in Traits Private Abstract Methods in Traits Variance Support Variance Support Covariance Contravariance SPL Differences: SplFileObject SPL Differences: SplHeap SPL Differences: SplDoublyLinkedList SPL Autoloading: spl_autoload_register() Lab: Core OOP Coding Differences 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 Numeric Strings BC Breaks Numeric Strings BC Break Examples Comparison Madness Comparison Examples String Handling: Needle Argument Differences If No Needle v*printf() Changes substr*() NULL Length Crazy Uncle implode() Second Param parse_str() Locale Independent Float-to-String Locale Independent Float-to-String No More Function Overloading Function Overloading Example Array Handling Differences Array Curly Brace Usage Hello, Operator? Non Scalar Operands Constants Are Now Constant File Handling Function Differences Disable Functions Disable Functions Example Security Related Function Changes Security Function Change: assert() Security Function Change: password_hash() Security Function Change: crypt() URL Handling Changes Misc Changes Changes Pertaining to Windows Lab: Procedural Programming Differences 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. https://php-cl.com This unit includes the following topics: Extension Gotchas Objects Rather Than Resources Objects Rather Than Resources Objects / Resources: XML Parser XMLWriter Differences CURL Extension Gotchas Mbstring Extension Gotchas Mbstring Extension Gotchas: mb_ereg* Mbstring Extension Gotchas: mb_ereg* Mbstring Extension Gotchas: mb_strrpos Mbstring Removed Aliases Mbstring Extension Gotchas: Other PCRE Extension Gotchas PCRE Extension Gotchas Example Intl Extension Gotchas Database Extension Gotchas PDO Gotchas GD Extension Gotchas GD Extension Gotchas Reflection Extension Gotchas Reflection Extension Gotchas Reflection Extension Improvements Zip/ZipArchive Extension Gotchas ZipArchive ZipArchive Example Misc Extension Gotchas Lab: Extension Gotchas New Cool Stuff This is the part you all have been waiting for, right? The new **cool stuff**. Without further ado, let's roll! This unit includes the following topics: New Cool Stuff JIT Compiler JIT Compiler: How to Enable JIT Compiler: Controls JIT Compiler: Controls Continued JIT Example The Case for Union Types Union Types: Syntax Union Types: Exceptions Mixed Types Mixed Types Example Mixed Types Impact on Variance Mixed Types Impact on Variance Weak References Weak Reference Example Weak Map Weak Map Usage Example Variadic Operators Nullsafe Operator Nullsafe Operator Short-Circuiting Match Expressions Match Expressions: Considerations Match Expressions: No Silent Coercion Static Return Type Named Arguments Named Arguments: Order Independence Named Arguments: Skipping Defaults Attributes Attribute Syntax Simple Attribute Example Attribute Use Case: Original Attribute Use Case: Revised Attribute Class Constructor Argument Promotion Constructor Argument Promotion Lab: Cool Stuff Lots of Improvements There have been many improvements in syntax and general handling of classes and functions in PHP 8. A number of improvements were actually first tested in PHP 7.4, and fully implemented in PHP 8. This unit includes the following topics: Lots of Improvements Typed Properties Typed Properties Typed Properties Arrow Functions Arrow Functions Arrow Functions OOP Syntax Improvements Uniform Variable Syntax What's "De-Referencing"? Uniform String Dereferencing Dereferencing Constants Expressions Anywhere Extended Use of ::class No Comma Left Behind JSON is Here to Stay! Try/Catch/Finally New Stuff array_splice() Improvements array_splice() Example array_slice() Performance Boost array_slice() Example String Handling Enhancements Stable Sorting Stable Sorting Example Affect on Keys in Stable Sorting Illegal Sort Functions Strings: Beginning, Middle and End Strings: Beginning, Middle and End Strings: str_contains SQLite Authorizer Other Improvements Other Improvements Other Improvements Cool Stuff in Extensions As well as core additions, there have been a number of incredibly use enhancements in a number of PHP extensions. This unit focuses on new and cool stuff in PHP 8 extensions. This unit includes the following topics: Extension Cool Stuff OpenSSL Improvements New Tokenizer Class New Tokenizer Class Security Filtering Improvements Improvement in Timezone Change Handling DateTime Creation PHP Web Extension Improvements Miscellaneous Extension Improvements Lab: Cool Stuff in Extensions 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 Using @ Operator With error_reporting() Inheritance and Method Signatures Error Related INI Directives Compile Time Warning Changes Clean Shutdown Non Capturing Catches Lab: Error Handling 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 Things Removed Each What, You Say? __autoload: Loads No More Removed Classes Security Related Removals Removals Related to Extensions Misc Extension Removals Lab: Deprecations Fees Originally priced at $700, the course fee has been reduced by 50% to help potential attendees who are affected by the worldwide pandemic. Until the end of the year, as an added bonus for signing up for the course, we are offering a free 30-day trial account on the LfPHP Cloud Service.
