help with php_pdf?

Hi, I just installed PHP 4.3.2 and tried to run php_pdf. I found that I was able to generate a pdf in memory using pdf_open_file($pdf), but when I tried to generate a real file using pdf_open_file($pdf,$filename) nothing happened, no file was generated. What's going on? Just as a sanity check I did an fopen($filename,"w") and that worked fine. I did replace my existing php.ini with the new php.ini-recommended, but I don't think I'm missing anything there. Thanks in advance for your help. _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus
