Cross Ref > Tool Basics

With PHP, you simply copy your files to a web server that is capable of running PHP pages.

To deploy a Paradox application, you need to deploy either the full version of Paradox or the Paradox Runtime both of which will include the BDE as well as any dependecies you've added such as psSendMail DLL, ezDialogs, etc.

Many developers just use a text editor. There are many PHP editors available including phpDesigner, and Delphi for PHP.

Corel Paradox for Windows (was Borland Paradox). Also, Borland used to offer a Paradox for DOS tool which support it's Paradox Application Language (PAL) which is not compatible with ObjectPAL. The biggest drawback to Paradox is that Corel does not have anyone at Corel actively developing Paradox for Windows (as opposed to Microsoft Access which does).

 ObjectPAL Development Tools

.php is the default extension for PHP although some developers will change the default extension in an effort to add an additional security level. If your code is tied to a particular version of PHP then some developers at the major PHP version number to the extension as in .php3, .php4, .php5, etc. 

.phtml is also sometimes used especially for files that contain both HTML and Perl code.

Paradox for Windows has two primary file types: source files and delivered files:

Source Files
Source files in Paradox are binary but can can be opened in later versions of Paradox and even in earlier versions if you don't use any new features.

• .FSL = Form
• .RSL = Report
• .SSL = Script
• .LSL = Library

Since Paradox source files do not compile to an EXE, Paradox developers tend to use a startup form or script to start the application.

 ObjectPAL File Extensions  

PHP is a hybrid language with both traditional PHP and OOP features. PHP is widely-used general-purpose scripting language that is especially suited for web development and can be embedded into HTML. PHP has been used to create some amazing web content, particularly outstanding message boards.

Target Platforms: PHP is most suitable for creating websites targeting any browser (any web server with PHP installed).

Language Overview: Object based language. Although ObjectPAL uses object oriented techniques "under the hood", it is not object oriented. Although you cannot create classes, ObjectPAL has built-in objects you can use in your code. You code in a traditional approach attaching code to objects or within a script. Most Paradox applications are form based. You may have a short startup script but you design forms and reports and tie them together with a common form. You can store reusable code such as custom methods and procedures in a library.

Target Platforms: Corel Paradox is most suitable for creating business desktop applications that run within Corel Paradox for Windows.

No built-in report writer but because website development targets a client browser (a document interfaced GUI), a common solution is to simply output an HTML formatted page with black text and a white background (not much control but it does work for some situations).

Paradox offers a built-in reporting tool that will suffice for most desktop database applications.
