php-fpm 5.4.38中不存在apache_request_headers（）？

Question

我能找到的所有文档都说apache_request_headers()应该可以在PHP（甚至是FastCGI）5.4版本中使用，但我没有它（CentOS 6）：

$ echo "<?php echo apache_request_headers();" | php
PHP Fatal error:  Call to undefined function apache_request_headers() in - on line 1

我错过了什么吗？

再次阅读文档......您似乎是从命令行运行它。

5.5.7此功能在CLI服务器中可用。
