昨天安装了echo模块。于是有点凌乱了
俺一直以为
$document_root$fastcgi_script_name链接起来就是SCRIPT_FILENAME
这个值应该和
$request_filename 一致，
应该就是要访问的php文件在硬盘上物理路径。
但是用echo模块后发现request_filename变量可以为空。

location ~ \.php$ {
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
t1.php=============这个就是t1.php的内容。解析完全正确
document_root: /data/wwwroot/test1/test2/t1.php
fastcgi_script_name: /t1.php
uri: /t1.php
request_uri: /testxxx/t1.php
request_filename:
==========================
求问：为什么request_filename为空。但是内容还能被解析出来呢？
难道 SCRIPT_FILENAME的值才是要访问的实际文件么？？
为什么 document_root和fastcgi_script_name拼接出来的值居然是/data/wwwroot/test1/test2/t1.php？？
