Zend Optimizer不能正常加载

Apache 2.0.63

PHP 5.2.8

Zend Optimizer 3.3

 

编译安装后，phpinfo()显示没有Zend Optimizer信息。

2）是否编译和路径问题？

Zend Optimizer did not load
The following phpinfo() output was not displayed:
... with Zend Optimizer vX.Y.Z, Copyright (c) 1998-2007 by Zend Technologies.

It could be that...

• PHP was compiled with debug support.
  The phpinfo() output will indicate that ZEND_DEBUG is 'enabled'. Recompile PHP without the debug support.
  
• PHP used the wrong php.ini or the correct php.ini did not include the optimizer directives.
  To identify if the wrong php.ini file was used, run a trace on httpd -X (in the case of Apache module) or on a standalone PHP exec (in the case of cgi) to see which files it tried to open.
  
• The Zend Optimizer directives in the php.ini file are incorrect.
  For example, there may be typos, the path to the optimizer is incorrect, the Zend Optimizer filename was not entered with the correct case, or the directives included extra white space at the beginning of a line or around a '='.
  
• You are working with the wrong web server installation.
  (This will only occur when there are different installations.)

查明是因为php.ini 的位置问题。
