Convert PHP to PDF: Creating High-Quality Code PDFs

Exporting PHP source code to PDF is useful for documentation, code reviews, compliance archives, tutorials, and client delivery. A well-formatted PDF makes code easier to read, share, and print — especially when syntax highlighting and line numbers are preserved.

This guide walks you through four practical methods, from the quickest manual option to a fully automated developer pipeline.

Quick Navigation

• Method 1 — Print PHP Code to PDF in a Browser
• Method 2 — Export PHP Code to PDF with VS Code
• Method 3 — Convert PHP to PDF Using Online Tools
• Method 4 — Convert PHP to PDF with Python

Why Convert PHP Code to PDF?

Developers and teams convert PHP code to PDF for several common reasons:

• Documentation — Include readable code in technical manuals
• Code Reviews — Share snapshots without exposing repositories
• Client Delivery — Provide non-editable reference materials
• Training & Tutorials — Print-friendly learning resources
• Archival & Compliance — Long-term, tamper-resistant storage

If visual clarity matters, syntax highlighting and clean layout are essential.

Method 1 — Print PHP Code to PDF Using a Browser (No Syntax Highlighting)

This is the quickest way to turn PHP code into a PDF using tools you already have. It works by printing the file directly from your browser, making it ideal for simple sharing and temporary documentation. However, since browsers treat the file as plain text, visual formatting is very limited.

Skill level: Beginner

Syntax highlighting: No

Steps

1. Open your .php file in a web browser (e.g. Google Chrome).
2. Press Ctrl + P (Print).
3. Choose Save as PDF as the printer.
4. Click Save.

Pros

• No installation required.
• Works on any operating system.
• Fastest workflow.

Cons

• No syntax highlighting.
• Plain formatting.
• Harder to read for large files.

This is a quick “good enough” option when formatting does not matter.

Method 2 — Export PHP Code to PDF with VS Code (High Visual Quality)

If presentation quality matters, exporting from a modern code editor is a great choice. VS Code can generate polished PDFs that closely match what you see in the editor, including themes, fonts, and spacing. This makes it especially suitable for tutorials, documentation, and code samples.

• Limited customization.
• Not ideal for sensitive projects.

Best for quick, non-confidential tasks.

Method 4 — Convert PHP to PDF with Python (Full Control & Automation)

For developers who need automation and precise formatting control, a programmatic solution is the most powerful option. This method converts source code through a customizable pipeline, making it perfect for batch processing, report generation, and engineering workflows. It requires some setup but delivers the most flexibility and scalability.

Best for: Automation, batch processing, custom styling

Skill level: Intermediate → Advanced

Syntax highlighting: Yes (professional quality)

from spire.doc import *

# ==============================
# Read PHP file
# ==============================
code = Path(r"C:\Users\Administrator\Desktop\Demo.php").read_text(encoding="utf-8-sig")
lines = code.split("\n")  # preserve real lines

# ==============================
# Create Word document
# ==============================
doc = Document()
section = doc.AddSection()
section.PageSetup.PageSize = PageSize.A4()
section.PageSetup.Margins.All = 40

# ==============================
# Create table
# ==============================
table = section.AddTable(True)
table.ResetCells(len(lines), 2)

table.PreferredWidth = PreferredWidth(WidthType.Percentage, 100)

for i in range(table.Rows.Count):
    row = table.Rows[i]
    row.Cells[0].SetCellWidth(8, CellWidthType.Percentage)
    row.Cells[1].SetCellWidth(92, CellWidthType.Percentage)

# ==============================
# Syntax highlighter
# ==============================
formatter = RtfFormatter(fontface="Consolas")
lexer = PhpLexer(startinline=True)

# ==============================
# Fill table
# ==============================
line_no_width = len(str(len(lines)))

for i, line in enumerate(lines):
    # Line number
    num_para = table.Rows[i].Cells[0].AddParagraph()
    num_para.AppendText(str(i + 1).rjust(line_no_width))

    # Highlight PHP
    rtf = highlight(line if line.strip() else " ", lexer, formatter).rstrip()
    rtf = rtf.replace(r"\f0", r"\f0\fs26") # font size

    code_para = table.Rows[i].Cells[1].AddParagraph()
    code_para.AppendRTF(rtf)

# ==============================
# Border styling
# ==============================
