pdf_new() uncalled Function

Hi, I use Linux, and I had installed PHP using yum install php. I am trying to use the pdf_new function to create pdfs from existing text files, but I get this error PHP Fatal error: Call to undefined function pdf_new() I have noticed that when I run the phpinfo() command, I cannot find the PDF phrase at all. My php.ini file does not even have these two lines extension=php_pdf.dll extension=php_cpdf.dll Could anyone suggest me what kind of command I should use if I need to build PDFs using PHP on a Linux system? Thanks in advance. Alice _________________________________________________________________ Express yourself with gadgets on Windows Live Spaces http://discoverspaces.live.com?source=hmtag1&loc=us
