PDF Page Counter for All Sub-folders by PHP Script – Complete Guide
If you need to count pages across multiple PDF files stored in a directory — including all sub-folders — PDF Page Counter for All Sub-folders by PHP Script is an ideal solution. Developed by VeryPDF, this tool allows users to recursively scan folders, accurately count pages of all PDF files, and export results into a CSV file for further analysis or reporting.

What is PDF Page Counter for All Sub-folders?
This tool is a PHP-based script designed for:
- Recursive directory scanning: It automatically scans a target directory and all nested sub-folders for PDF files.
- Accurate page counting: Unlike simple methods that rely on searching PDF text for /Page or /Count, this script accounts for different PDF structures, including compressed page trees, to ensure accurate results.
- Batch processing: It can handle hundreds or thousands of PDFs at once.
- Exportable reports: The results are exported into a CSV file, which can be opened in Excel, LibreOffice, or other spreadsheet tools.
Use cases include:
- Verifying page counts of multiple PDFs before printing or distribution.
- Auditing incoming or outgoing PDF documentation.
- Estimating printing requirements for large batches of PDFs.
- Generating reports for project management or documentation purposes.
Why Use This Tool Instead of Writing Your Own Script?
While PHP offers libraries for PDF parsing (like FPDI or TCPDF), counting pages reliably across all PDF types can be tricky:
- PDFs often contain compressed or nested page trees. A simple text search for /Page or /Count might give incorrect results.
- Some PDFs have encrypted or restricted content, requiring special handling.
- Manually coding recursive folder traversal, page extraction, and CSV export adds development overhead.
This PHP script handles all of the above internally, saving time and ensuring accuracy.
Installation & Setup
1. Download the Script
Purchase or download the script from VeryPDF: PDF Page Counter for PHP Script
2. Prepare Your Environment
- Ensure PHP CLI is installed on your system.
- Place the downloaded script in a directory, for example:
- /path/to/pdf-page-counter/
- Make sure the script has read permissions on the folder containing your PDFs.
3. Prepare the Target Directory
Assume you have a folder structure like:
/home/user/docs/
-- report1.pdf
-- report2.pdf
folderA/
-- sub1.pdf
-- sub2.pdf
folderB/
-- doc1.pdf
The script will scan /home/user/docs/ and all its subdirectories.
Command-Line Usage
If the script file is named pdf_page_counter.php, you can run it from the command line:
php /path/to/pdf-page-counter/pdf_page_counter.php /home/user/docs/ /home/user/output/report.csv
- First argument: Path to the root directory containing PDFs.
- Second argument: Path and filename for the output CSV report.
The script will recursively count pages in every PDF it finds and export a CSV file containing:
- File path
- File name
- Page count
You can open the CSV in Excel or LibreOffice Calc for sorting, filtering, or aggregating total page counts.
Integrating in PHP Code
You can also call this script from a PHP program, for example in a web application:
<?php
$rootDir = '/home/user/docs/';
$outputCsv = '/home/user/output/report.csv';
$cmd = 'php /path/to/pdf-page-counter/pdf_page_counter.php '
. escapeshellarg($rootDir) . ' '
. escapeshellarg($outputCsv);
exec($cmd, $outputLines, $exitCode);
if ($exitCode === 0) {
echo "PDF page counting completed. Report saved at: $outputCsv\n";
} else {
echo "Execution failed. Exit code: $exitCode\n";
print_r($outputLines);
}
?>
This allows you to integrate PDF page counting into your workflow automation, web applications, or backend scripts.
Example Output
Given the folder structure above, the exported CSV may look like:
File Path,File Name,Page Count
/home/user/docs,report1.pdf,5
/home/user/docs,report2.pdf,12
/home/user/docs/folderA,sub1.pdf,20
/home/user/docs/folderA,sub2.pdf,8
/home/user/docs/folderB,doc1.pdf,15
You can now:
- Sort by page count to find the largest documents.
- Aggregate page counts for total pages.
- Group by subfolder for project-level reporting.
Common Issues and Tips
|
Issue |
Solution |
|
PDF files are password protected |
Remove passwords or use PDFs that the script can read. Encrypted files may not be counted. |
|
Large number of PDFs |
Scanning thousands of PDFs may take time. Run in command line or schedule during off-peak hours. |
|
Special characters in file paths |
Ensure proper escaping in command line or use escapeshellarg() in PHP. |
|
Permissions |
Make sure the PHP script has read access to all directories and subdirectories. |
|
Complex PDF structures |
The script handles most PDF page tree complexities to ensure accurate counts. |
Summary
PDF Page Counter for All Sub-folders by PHP Script is a professional tool for anyone who needs to:
- Recursively count PDF pages in large folder structures
- Ensure accuracy for complex PDFs
- Export organized reports for Excel or CSV
- Automate PDF page counting in PHP scripts or backend workflows
It saves time, avoids errors from manual counting, and provides a reliable solution for businesses, print management, and document auditing.
