ข้อแรกคือ output buffering = off ให้ on เสีย แม้จะทำให้ช้านิด แต่จะแก้ปัญหาเรื่อง error เกี่ยวกับ header ได้

ข้อสอง ในกรณีที่ใช้ php-NUKE เป็น main น่าจะลองปรับแก้ output handler เป็น ob_gzhandler และปรับ output_buffering=off

หลังจากนั้นให้ restart apache ใหม่ทุกครั้งถ้ามีการปรับแก้ อ้อ เกือบลืม
การปรับแต่งapache ให้สามารถใช้ php ได้
1.เข้าดูในไฟล์ /etc/httpd/httpd.conf หรือถ้าในกรณีที่เราสร้าง apache แบบ apache profile จะอยู่ที่ /usr/local/apache2/conf/httpd.conf
2.ใส่บรรทัด LoadModule php4_module libexec/libphp4.so
AddModule mod_php4.c
AddType application/x-httpd-php .php
บางทีก็แค่เอา # ออกก็ได้ครับ

3.restart apache
