Auto_prepend_file在cli模式下不工作

我的mac上无法运行auto_prepend_file:

# cat /opt/local/lib/php/test.php
<?php
function test() { return 'foo'; }
# php --ini | grep php.ini
Configuration File (php.ini) Path: /opt/local/etc/php5
Loaded Configuration File:         /opt/local/etc/php5/php.ini
# cat /opt/local/etc/php5/php.ini | grep auto_prepend_file
auto_prepend_file = "/opt/local/lib/php/test.php"
# ls -la /opt/local/etc/php5/php.ini
-rw-r--r--   1 root  admin  68630 Jul 27 13:53 /opt/local/etc/php5/php.ini
# php -r "echo ini_get('auto_prepend_file');"
/opt/local/lib/php/test.php

然后……

# php -r "echo test();"
Fatal error: Call to undefined function test() in Command line code on line 1
# php -i | grep auto_prepend_file
auto_prepend_file => /opt/local/lib/php/test.php => /opt/local/lib/php/test.php

它通过(重启的)apache工作。
