About PHP3 files
A .PHP3 file is a legacy server-side web script written in PHP 3. It contains source code designed to be executed by a web server to generate dynamic HTML content.
You can open and edit a .PHP3 file using any standard text or code editor, such as Notepad++ or Visual Studio Code. To learn more about the language's history, visit the PHP Wikipedia page.
Dealing with .PHP3 files today presents significant challenges. Because PHP 3 was released in 1998, modern web servers are no longer configured to recognize or execute the .PHP3 extension. If you click a link to a .PHP3 page, your browser will likely download the raw source code instead of displaying a web page. Furthermore, the syntax heavily relies on deprecated functions that modern PHP 8+ interpreters will instantly reject.
The best conversion targets for a .PHP3 file are PHP (if you plan to update the code for modern servers) or TXT (for safely reading the code without triggering security blocks). Converting the file to HTML will only show the raw code, not the rendered web page, because the code must be executed by a server to produce the actual interface.
While this file format is essentially plain text, the legacy scripting syntax makes it difficult to convert or execute in modern environments. Often, only manual code refactoring can properly migrate the data. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your file to identify the format, view it, and convert it when possible.
Convert.Guru analyzes your PHP3 file, detects the exact format, and lets you read the text inside.
If you want to convert PHP3 file to HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP, JSPX, PY, RB or PL, you can use PHP or similar software from the "Legacy Server-Side Web Scripting" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to PHP3, try PHP or another comparable tool in the "Legacy Server-Side Web Scripting" category.
The PHP3 Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PHP3 converter.
