Deprecation of PHP Commands & Removal of 4D Built-in PHP Interpreter

October 19, 2023

PHP has played a crucial role in web development, and it was introduced into 4D v12 to offer features not readily available in the native language, such as zip, hash, or LDAP functionality. Over time, 4D has incorporated many of these PHP features into its core functionality. As a result, we decided to remove the built-in PHP interpreter in 4D v20 R3 and begin the deprecation process for PHP commands in v21.

While we won’t entirely remove the PHP commands from 4D, we strongly encourage you to use the system workers to execute PHP code in the future.

This blog post will guide you through this transition process, demonstrating how to use an external interpreter through PHP Execute and explaining how to execute PHP code effectively with a system worker.

Invisible Characters on Stage!

July 20, 2021

Best practices in IT sometimes change, and the management of certain invisible characters in text files is one example. End of Line (EOL) characters have evolved, especially for version control systems integration purposes. In the same way, the Byte Order Mark (BOM) on Unicode text files is less and less used.

With 4D v19 R2, 4D has evolved smoothly to follow these best practices, giving you more flexibility along the way.

XPath is a language allowing you to easily work with your XML documents. It’s already usable via the DOM Find XML element command and with 4D v18 R3, the support of the XPath syntax has been drastically enhanced. If you’re among those who requested features such as using a wildcard in a path, then keep reading!

Welcome to our ongoing series about compatibility settings and “hidden” features for improved performance. In the first post, we looked at the QUERY BY FORMULA command and its impact on an application’s behavior. The second post was about the “Use period and comma as placeholders” compatibility option to avoid running into “the numbers are displayed as >>>>>>>>>” hassle.

In this third installment, we’re going to explore Nested Transactions.

Compatibility settings – Use period and comma as placeholders (Part 2)

September 24, 2018

We’ve started a series of blog posts on compatibility settings and the secret options that can drastically help you improve the performance and the behavior of your applications. The first post was about QUERY BY FORMULA.

The second part of the compatibility series is about international usage of your business applications. This could mean selling to other countries – or having coworkers coming from other countries to work for a while, but using their local systems.

If you’ve ever seen or gotten reports like “the numbers are displayed as >>>>>>>>>”, this blog post is for you.

Compatibility settings – or driving with the parking brake on(Part 1)

August 22, 2018

In code kitchens, I usually spend some time with the database settings, especially with the Compatibility settings. Often certain settings don’t follow best practices and during discussions with the application developer, I hear “oh, I never changed these” or “I’m not sure about the impact, so better not touch them”.

Since they could drastically impact the performance or behavior of your applications, we’ve begun a series of blog posts to discuss some of these “secret” settings.
