I compiled and installed php4 for the first time and it seems that all went right ,execute normal html page and CGI page such as .cgi .pl no any problem ,but when I try to execute any sort of php script I?m stuck with an
 Internal Server error and error_log says:

  Premature end of script headers: /usr/local/httpd/cgi-bin/test.php

 I check the system as following:
    
   a. -/httpd -l : it list all the compile module , the "mod_php4.c" include in it .
   b. check the server_software with perl is : "Apache/1.3.17 (unix)php/4.0.4pl1"

 Thanks for reply.
