Convert PHP to PDF

A fixed-layout copy is needed when a PHP-generated page must be printed, submitted, shared, or archived. The PHP source itself must either be executed to produce the page or formatted as code; it is not directly rendered into a finished PDF by a normal file converter.

What the PHP format is

PHP is a server-side scripting language used by web developers and administrators to generate dynamic pages, forms, invoices, reports, and API responses. A .php file contains source code, usually mixed with HTML, CSS, SQL, or template markup; PHP is a programming language rather than a document format.

A PHP-enabled web server interprets the file and returns generated output, normally HTML, to a browser. Opening a .php file from a file manager does not run its server-side code: it may display source text or fail to load, depending on the operating system and application.

What the PDF format is

PDF is a fixed-layout document format that preserves page dimensions, fonts, images, spacing, and pagination across operating systems and devices. Recipients can print or view it without PHP, a web server, or the application that created the original page.

PDF is suitable for invoices, official submissions, email attachments, and archival copies. It is not normally intended for editing like a word-processing file, and conversion does not guarantee a smaller file; embedded fonts and images can increase its size.

Convert the generated PHP page

Use this method when the required PDF is a report, receipt, form, or other page produced by the script.

1. Install PHP and, if required, a local server package such as XAMPP, Laragon, or MAMP. PHP's built-in server is sufficient for many self-contained projects.
2. Place the project in its document directory and configure required databases, environment variables, extensions, included files, and writable folders.
3. From the appropriate project or document-root directory, run php -S localhost:8000. The command starts a development server; it is not a production deployment.
4. Open the relevant address, such as http://localhost:8000/report.php, in Chrome, Edge, or Firefox and verify that the page contains the expected data.
5. Use Print → Save as PDF in the browser. Select the required paper size and margins, enable background graphics when the design uses them, and inspect page breaks, images, headers, and footers in print preview.

For repeatable server-side output, use a headless Chromium workflow with Playwright or Puppeteer and its PDF function. Supply the same print CSS, viewport, paper format, margins, and page-loading conditions used in production; wait for network requests and JavaScript-rendered content before generating the PDF.

If the page is already available as HTML, reputable online services such as PDFCrowd or CloudConvert can provide HTML-to-PDF conversion. Upload generated HTML rather than the original .php file: these services generally do not execute arbitrary PHP, and external stylesheets, fonts, images, sessions, and authenticated data may not be available to them.

Convert the PHP source code

Use this method when the source itself is the document, for example for code review, training material, or a paper record.

1. Open the file in a code editor such as PhpStorm, Notepad++, or Visual Studio Code and enable PHP syntax highlighting.
2. Set a readable monospaced font, suitable margins, line wrapping, and optional line numbers. Disable wrapping if preserving exact source lines is more important than fitting the code to the page.
3. Print from an editor that supports printing, such as Notepad++ or PhpStorm, and choose a system PDF printer: Microsoft Print to PDF on Windows or Save as PDF in the macOS print dialog. Visual Studio Code may require a printing extension or an intermediate HTML export.

For automated source-code PDFs, apply syntax highlighting with Pygments or a similar formatter, export the result as HTML, and print that HTML through Chromium. This documents the source text; it does not execute PHP or capture the page generated by the script.

Generate PDFs inside a PHP application

For recurring invoices, reports, or forms, a PHP application can create PDFs from templates with libraries such as Dompdf, mPDF, or TCPDF. This is PDF generation rather than file conversion and requires code, dependency installation, template preparation, and testing of CSS support.

Quality and security limitations

Authentication, database results, missing PHP extensions, permissions, relative paths, external CSS, web fonts, JavaScript, and browser print CSS can change the rendered result. Test with representative data, verify images and page breaks, and compare the PDF with the page at the intended URL.

Do not upload confidential PHP source, credentials, customer data, or private generated pages to an online converter. A local browser, headless Chromium process, or PHP PDF library avoids exposing those files and permits access to local dependencies. Remove secrets from source-code PDFs and check that generated PDFs do not contain unintended metadata or hidden form data.
