How can one properly integrate a PDF library into PHP and troubleshoot common errors like "Fatal error: Call to undefined function: pdf_new()"?

To properly integrate a PDF library into PHP and troubleshoot common errors like "Fatal error: Call to undefined function: pdf_new()", you need to ensure that the PDF library is installed and enabled in your PHP configuration. This error usually occurs when the necessary PDF functions are not available due to missing or misconfigured extensions. To fix this error, you can check if the PDF extension is enabled in your php.ini file by searching for "extension=pdf.so" (for Linux) or "extension=php_pdf.dll" (for Windows) and uncommenting it if necessary. Additionally, you may need to restart your web server after making changes to the php.ini file for the changes to take effect. 

<?php
// Check if the PDF extension is enabled
if (!extension_loaded('pdf')) {
    echo 'PDF extension is not enabled. Please enable it in your php.ini file.';
} else {
    // Your PDF generation code here
}
?>
