1. How to Define PHP Routes for HTTP Requests using PHP 8 Attributes to Extract Details from Routing Class Code

Updated on: 2022-09-29

Posted on:

Blog: Potato Service package blog
Package: Potato Service

PHP 8 implements the possibility to extract attributes defined in comments of PHP classes using PHP reflection support.

This package uses this possibility to implement an MVC framework that developers can use to configure HTTP request routes using route classes that comment attributes that define the details of the routing of HTTP requests to controller classes.

This way, developers can define the PHP application HTTP request routing configuration in the same class file that implements the routing code.

This possibility makes it easier to maintain complex PHP applications because it avoids the need to define routing PHP code in a separate file from the routing configuration.

1. How to Implement a PHP Hash Generator That is Simple Fast in Pure PHP

Updated on: 2022-09-26

Posted on:

Blog: PHP Murmurhash package blog
Package: PHP Murmurhash

Hashing is an operation that computes a value from a string of data.

Hashing operations help check the integrity of data that may be transmitted between a source computer and a destination computer to detect data transmission failures caused by external interferences.

In environments in which security is an important aspect, developers should use cryptographic hashing algorithms to detect malicious alteration of data by people with bad intentions.

In environments where security is not essential due to the low risk of alteration of data by bad-intentioned people, developers can use non-cryptographic algorithms.

Such algorithms do not require so much CPU processing power and can run faster.

Murmurhash is a non-cryptographic algorithm.

This package provides a pure PHP implementation of the Murmurhash algorithm. Therefore it does not require that particular cryptography PHP extensions are available to use this class.

1. How to Set or Get the PHP Types of Variables Without the Risk of Committing a Mistake When You Type the Variable Type Names

Updated on: 2022-09-23

Posted on:

Blog: PHP Type Class package blog
Package: PHP Type Class

PHP is a weakly typed language. This fact means that it allows setting the type of variable values when executing the PHP code.

Although this makes the PHP language very flexible and tolerant of the developer's mistakes, sometimes it can be hard to debug subtle bugs caused by the developer's errors.

In practice, that can mean that developers may take more time to fix subtle bugs that probably would not exist if PHP was a strongly typed language.

This package provides a solution that can help to avoid those bugs. It gives the name strings of the PHP variable types.

So, if a developer wants to use the PHP GetType and SetType functions to get or set the variable type, the developer can use this class.

So, if the developer makes a mistake in the name of a constant provided by the class, PHP will trigger an error that can make it easier to find bugs caused by typing the name of a PHP type.
