note 43997 added to ref.image

i install php-4.3.7,apache-2.0.50,mysql-4.0.20 on win2Kpro. The extension of php_gd2.dll is added default to php.ini.But when i call the function imagecreate(), there comes an error says "fatal error: Call to undefined function: imagecreate() in C:\Program Files\Apache Group\Apache2\htdocs\upload_url\myimage.php on line 5" The manual says the gd library is binded to new version of php(mine is 4.3.7),then why can't i use this function? ---- Manual Page -- http://www.php.net/manual/en/ref.image.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+43997 Delete -- http://master.php.net/manage/user-notes.php?action=delete+43997&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+43997&report=yes Search -- http://master.php.net/manage/user-notes.php
