PHP4Delphi is a visual development software framework for creating custom PHP extensions using Delphi. PHP extension, in the most basic terms, is a set of instructions that is designed to add functions to PHP.

PHP4Delphi is organized into several subprojects:

PHP4Delphi allows executing PHP scripts within a Delphi program using TpsvPHP component directly without a web server. It is a scripting for applications (like Visual Basic for Applications (VBA) for Microsoft Office) that enables writing client-side graphical user interface (GUI) applications or server-side PHP support in case if you are developing PHP enabled web servers. One of the goals behind it was to prove that PHP is a capable general-purpose scripting language that is suited for more than Web applications only. With PHP4Delphi you can use Delphi forms instead of web-forms, pass parameters to script directly.

The visual development framework gives the possibility to create custom PHP extensions using Delphi.

PHP4Applications allows integrating PHP in any application. It supports C#, C, C++, Visual Basic, Visual Basic for Applications (VBA), Delphi, Delphi .NET, Visual Basic (.NET), etc.
