About PHP3 files
A .php3 file is a legacy web script written for PHP Version 3, a server-side language released in 1998. While acceptable in the late 90s, these files are now technically obsolete. The primary constraint users face is that modern web servers (like Apache or Nginx) often do not recognize the .php3 extension by default. Instead of executing the code, the server may serve the file as a plain text download, disastrously exposing your source code, database credentials, and logic to any visitor.
To use these files today, you typically need to "convert" them by renaming the extension to PHP to attempt execution on a modern stack, though this often fails due to deprecated functions (e.g., register_globals). For safe archiving or code review without setting up a complex LAMP stack, the best workflow is converting the source code to TXT for universal readability or PDF for documentation.
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 "Server-side Web Script" 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 "Server-side Web Script" 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.
