PHP Convert Docx to PDF

Here's how you can do it:

1. Install LibreOffice:
   Ensure you have LibreOffice installed on your server. You can install it using the following command:

   sudo apt-get install libreoffice

   
   

2. Use PHP to call LibreOffice for conversion:
   Use PHP to execute a command that converts the DOCX file to PDF using LibreOffice.

Here is the PHP script:

<?php
function convertDocxToPdf($docxFilePath, $outputDir)
{
    // Ensure the output directory exists
    if (!is_dir($outputDir)) {
        mkdir($outputDir, 0777, true);
    }

    // Define the output file path
    $pdfFilePath = $outputDir . '/' . pathinfo($docxFilePath, PATHINFO_FILENAME) . '.pdf';

    // Command to convert DOCX to PDF using LibreOffice
    $command = 'libreoffice --headless --convert-to pdf --outdir ' . escapeshellarg($outputDir) . ' ' . escapeshellarg($docxFilePath);

    // Execute the command
    exec($command, $output, $returnVar);

    // Check if the conversion was successful
    if ($returnVar == 0) {
        return $pdfFilePath;
    } else {
        return false;
    }
}

// Usage example
$docxFilePath = 'path/to/your/document.docx';
$outputDir = 'path/to/output/directory';
$pdfFilePath = convertDocxToPdf($docxFilePath, $outputDir);

if ($pdfFilePath) {
    echo 'PDF created successfully: ' . $pdfFilePath;
} else {
    echo 'Failed to create PDF.';
}
?>
