OOP

Autoloading

See autoload_example.php Notes:

• __autoload() is deprecated in PHP 7 and removed in PHP 8
• Good source of test data: https://download.geonames.org/export/dump/countryInfo.txt
• Example of a class that uses static return data type
  • https://github.com/dbierer/PHP-8-Programming-Tips-Tricks-and-Best-Practices/blob/main/ch09/php8_static_return_type.php
  • https://github.com/dbierer/PHP-8-Programming-Tips-Tricks-and-Best-Practices/blob/main/src/Php8/Sql/Select.php

PHP Async

• For starters, see: https://www.zend.com/blog/swoole

Composer

Example of alternative repository other than packagist.org

• wpackagist.org
  • Add this to the composer.json file:

    "repositories":[
        {
            "type":"composer",
            "url":"https://wpackagist.org",
            "only": [
                "wpackagist-plugin/*",
                "wpackagist-theme/*"
            ]
        }
    ],
    "require": {
        "aws/aws-sdk-php":"*",
        "wpackagist-plugin/akismet":"dev-trunk",
        "wpackagist-plugin/wordpress-seo":">=7.0.2",
        "wpackagist-theme/hueman":"*"
    },

If you run into problems regarding unmatched requirements, add this flag: --ignore-platform-reqs

• Example: you're running PHP 8, and the Composer package requires PHP 7, but not 8
• Composer will install with this flag ... but there's still guarantee that the package runs in PHP 8

Web Services

SOAP vs. REST:

• Example of SOAP client:

Final Bindings

• Alternate form of documentation: Swagger
• https://swagger.io/
• Mainly oriented towards API development
• Also uses docblocks
• JIT
