I want to know how can I enable PDF files in a Xampp 1.7.4 with PHP version 5.3.5 and using Apache and MySQL database in a notebook with Windows Vista. What are the steps that I should follow to adapt this environment?? Is it only necessary to modify the php.ini, enabling extension=php_pdf.dll?? Where can I secure download php_pdf.dll?? In which directories should I put php_pdf.dll??
