Open .PHP files online
A .php file contains PHP source code. PHP is a server-side language built for the web that powers a large share of the internet, most notably WordPress. Code is embedded in HTML using <?php … ?> tags and executed on a server to produce the page sent to the browser.
Modern PHP is compiled to bytecode and cached (and JIT-compiled in PHP 8+), with robust typing and a rich ecosystem (Composer, Laravel, Symfony). Reading a .php file is how you understand a page or endpoint's server-side logic.
What is a `.php` file?
PHP files interleave HTML with PHP code blocks. A request to a .php URL is handled by the PHP runtime, which executes the embedded code and returns the output (usually HTML or JSON). Variables use a $ prefix; the language has classes, traits, and namespaces.
A .php file is plain text (UTF-8), MIME type text/x-php. It runs on a server with PHP installed; the viewer shows the source without executing it.

- Web applications with Laravel or Symfony
- Server-rendered pages and JSON APIs
- Legacy and shared-hosting web projects
How to open a `.php` online
Open the zip viewer in a new tab, then drop your .php onto the page — or click to browse for it, or paste a URL. The file opens in the Monaco code editor, with syntax highlighting, code folding, and find, read entirely on your device.
- Drag your
.phponto the page — or click to browse, or paste a URL. - It opens immediately in the Monaco code editor, with syntax highlighting, code folding, and find. No install, no sign-up.
- Read, search, or copy it. Your file never leaves your browser.
Open `.php` without uploading
Most "open php online" sites work by uploading your file to a server and processing it there. ZipTool does the opposite: it loads its parser once, then reads your .php locally in the browser tab. The contents stay on your device.
You can prove that in seconds. Open the page, press F12 for DevTools, switch to the Network tab, and open your file — no request carrying the file's contents is sent. You can also turn off Wi-Fi after the page loads and the file still opens. See security and privacy for the full picture.
Frequently asked questions
How do I open a .php file online?
Drag the .php onto the page (or click to browse, or paste a URL). It opens in the code editor so you can read the embedded PHP and HTML, search, and copy — it is not executed. The file is parsed entirely in your browser and never uploaded.
Can I view a .php without uploading it?
Yes. ZipTool reads the file locally in your browser tab — no upload, no server-side copy. Confirm it with DevTools (F12, Network tab) while opening the file, or by turning off Wi-Fi after the page loads and verifying the file still opens.
Will opening a .php show me the rendered web page?
No. The viewer shows the PHP source code as text. To see the rendered output you would need a PHP server to execute it. Viewing the source is useful for reading or auditing the logic without running it.
Is a .php file a text file?
Yes. PHP source is plain text (UTF-8), so a .php opens in any text or code editor. The <?php ?> tags are what make it PHP, but the file is readable text.
