about lambda expressions and lambda PHP functions, then step through different example–from basic lambda functions, recursive lambda functions, lambda functions in PHP arrays and in PHP classes.
In this section, you will find articles, tutorials, and snippets covering all areas of Application Architecture in PHP.
how to parse and serialize a JSON object, how to extract data from a database as a JSON string, how to store a JSON object into a database and in the last section of this article you have seen how to encrypt and decrypt a JSON object using OpenSSL.
In my previous article, I expanded a few ideas around test helpers and how to use setUp() and tearDown(). However, we still stayed in the realm of things built in to PHPUnit. Here, I want to expand on a helper function I include in most of my main testing classes that allows for the concept of setUp(), but grants a bit more flexibility.
CSV files are often employed to import data from an application such as MS Excel into a database. Rob Gravelle demonstrates how to write a PHP script that reads in a CSV file and converts its contents into a multi-dimensional array for insertion into a WordPress database.
Version 1.0 of the Zend Engine functions much like the heart and brain of PHP 4.0. It contains the process that provides the sub-structure and facilities to the functional modules. It also implements the language syntax, as well. The Zend Engine 1.0 is actually the second revision of the PHP scripting engine. It is still based on the same rules as the PHP 3.0 engine that was basically Zend Engine 0.5. Now it is permissible to migrate the path from PHP 3.0 to 4.0. The development has the same â??state of mindâ?? as per PHP 3.0. We feel it is right time to start working towards a revision of the Zend Engine. It would also incorporate new structures and solutions to some of the most difficult problems faced by the PHP designer or developers
The “remember me” feature on user login forms (long-term persistent authentication) is one of the most common and convenient web authentication features. It allows the user to be constantly authenticated in the application without having to enter username and password in each session. The feature is based on cookies and handling cookie data in PHP. Since we are talking about authentication, security is important and any possible security issues and solutions will be covered in this tutorial.
Test Driven Design is the process of writing unit tests first (expecting them to fail) and then writing the code to make the tests pass. The benefits of doing this include:
â?¢ forces the programmer to plan out the functionality head of time
â?¢ forces the functions to be small, concise, and testable
â?¢ leaves the programmer with a full unit test suite with 100% test coverage
One of the most common security features during the user registration process is e-mail verification. It is important to create it according to industry best practices in order to avoid potential security risks. Let’s discuss these best practices and see how to create e-mail verification in PHP.
The cloud is the newest buzzword in all things development, and there are many different options for utilizing the nebulous cloud. Amazon Web Services, Microsoft Azure, and Digital Ocean (just to name a few) are some providers that give you various levels of cloud computing. While all three give you Virtual Private Hosting, Microsoft has stepped up their offering.
WebSocket is a relatively new technology that enables a persistent connection between client and server over TCP protocol. In other words, it allows bi-directional socket connections to a server, where both server and client can send the data at any time. This article will focus on WebSocket’s security issues and possible solutions to its vulnerabilities.
