Setting up the Dompdf (a pdf generation package in php) in XAMPP in windows environment can sometimes be an issue.
After we have set up the package in the htdocs and go for testing the examples in the packages , error is encountered which is as follows-

A PHP Error was encountered Severity: Warning Message: domdocument::domdocument() expects at least 1 parameter, 0 given Filename: include/dompdf.cls.php Line Number: 165 Fatal error: Call to undefined method domdocument::loadHTML() in
C:xampphtdocsbambooinvoicebamboo_system_filespluginsdompdfincludedompdf.cls.php on line 284


The error message is caused due to a conflict between DomDocument and DomXML extentions , so the first thing we did was to disable the domdocument extention in php.ini.
extension = php_domxml.dll

So what we did was to comment out the PDFLib extension extension=php_pdf.dll in the php.ini file. After the modifications we restarted the apache and then the examples could be run on the XAMPP environment.
