服务器环境 linux/apache/mysql 问题描述         服务器开启了伪静态，并且也设置了伪静态文件.htaccess,但是伪静态不起作用，所有页面都跳转到了首页，我的伪静态文件如下： RewriteEngine on AcceptPathInfo On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} !\.(css|js|png|jpeg|gif)$ RewriteRule ^(.*)$ /index.php/$1 [QSA,PT,L] 复制代码解决思路         1、伪静态文件.htaccess是否起作用，于是我将我将首页修改为index.aaa RewriteRule ^(.*)$ /index.aaa/$1 [QSA,PT,L] 复制代码       此时发现网站是打不开的，所以断定伪静态文件起作用，并且能够定位到index.php.         2、此时分析可能是index.php 后的内容获取不到，获取此内容是通过path_info 进行获取，所以检测是否能够获取到path_info echo $_SERVER['PATH_INFO']; 复制代码       3、打印出来的结果为空白，继续打印$_Server; echo $_SERVER; 复制代码       打印出的结果为： array(64) {   ["DOCUMENT_ROOT"]=>   string(30) "/usr/home/qxu1780990217/htdocs"   ["GATEWAY_INTERFACE"]=>   string(7) "CGI/1.1"   ["HTTP_ACCEPT"]=>   string(63) "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"   ["HTTP_ACCEPT_ENCODING"]=>   string(13) "gzip, deflate"   ["HTTP_ACCEPT_LANGUAGE"]=>   string(59) "zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2"   ["HTTP_CACHE_CONTROL"]=>   string(8) "no-cache"   ["HTTP_CONNECTION"]=>   string(10) "keep-alive"   ["HTTP_COOKIE"]=>   string(42) "PHPSESSID=5d1dac4ecd19a129494040cd0bee0bfe"   ["HTTP_HOST"]=>   string(22) "qxu1780990217.my3w.com"   ["HTTP_PRAGMA"]=>   string(8) "no-cache"   ["HTTP_UPGRADE_INSECURE_REQUESTS"]=>   string(1) "1"   ["HTTP_USER_AGENT"]=>   string(73) "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:56.0) Gecko/20100101 Firefox/56.0"   ["PATH"]=>   string(13) "/bin:/usr/bin"   ["PHPRC"]=>   string(40) "/var/www/php54/hichina_ini/qxu1780990217"   ["QUERY_STRING"]=>   string(0) ""   ["REDIRECT_DOCUMENT_ROOT"]=>   string(30) "/usr/home/qxu1780990217/htdocs"   ["REDIRECT_GATEWAY_INTERFACE"]=>   string(7) "CGI/1.1"   ["REDIRECT_HTTP_ACCEPT"]=>   string(63) "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"   ["REDIRECT_HTTP_ACCEPT_ENCODING"]=>   string(13) "gzip, deflate"   ["REDIRECT_HTTP_ACCEPT_LANGUAGE"]=>   string(59) "zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2"   ["REDIRECT_HTTP_CACHE_CONTROL"]=>   string(8) "no-cache"   ["REDIRECT_HTTP_CONNECTION"]=>   string(10) "keep-alive"   ["REDIRECT_HTTP_COOKIE"]=>   string(42) "PHPSESSID=5d1dac4ecd19a129494040cd0bee0bfe"   ["REDIRECT_HTTP_HOST"]=>   string(22) "qxu1780990217.my3w.com"   ["REDIRECT_HTTP_PRAGMA"]=>   string(8) "no-cache"   ["REDIRECT_HTTP_UPGRADE_INSECURE_REQUESTS"]=>   string(1) "1"   ["REDIRECT_HTTP_USER_AGENT"]=>   string(73) "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:56.0) Gecko/20100101 Firefox/56.0"   ["REDIRECT_PATH"]=>   string(58) "/bin:/bin/sbin/:/usr/sbin/:/usr/bin/:/usr/local/bin/:/sbin"   ["REDIRECT_QUERY_STRING"]=>   string(0) ""   ["REDIRECT_REMOTE_ADDR"]=>   string(13) "36.24.243.135"   ["REDIRECT_REMOTE_PORT"]=>   string(5) "59458"   ["REDIRECT_REQUEST_METHOD"]=>   string(3) "GET"   ["REDIRECT_REQUEST_URI"]=>   string(11) "/brand.html"   ["REDIRECT_SCRIPT_FILENAME"]=>   string(41) "/usr/home/qxu1780990217/htdocs/brand.html"   ["REDIRECT_SCRIPT_NAME"]=>   string(11) "/brand.html"   ["REDIRECT_SERVER_ADDR"]=>   string(14) "139.129.150.40"   ["REDIRECT_SERVER_ADMIN"]=>   string(32) "webmaster@qxu1780990217.my3w.com"   ["REDIRECT_SERVER_NAME"]=>   string(22) "qxu1780990217.my3w.com"   ["REDIRECT_SERVER_PORT"]=>   string(2) "80"   ["REDIRECT_SERVER_PROTOCOL"]=>   string(8) "HTTP/1.1"   ["REDIRECT_SERVER_SIGNATURE"]=>   string(0) ""   ["REDIRECT_SERVER_SOFTWARE"]=>   string(6) "Apache"   ["REDIRECT_STATUS"]=>   string(3) "200"   ["REDIRECT_UNIQUE_ID"]=>   string(24) "Wt8iggqjzDYAADQ3dj4AAAAK"   ["REDIRECT_URL"]=>   string(11) "/brand.html"   ["REMOTE_ADDR"]=>   string(13) "36.24.243.135"   ["REMOTE_PORT"]=>   string(5) "59458"   ["REQUEST_METHOD"]=>   string(3) "GET"   ["REQUEST_URI"]=>   string(11) "/brand.html"   ["SCRIPT_FILENAME"]=>   string(40) "/usr/home/qxu1780990217/htdocs/index.php"   ["SCRIPT_NAME"]=>   string(10) "/index.php"   ["SERVER_ADDR"]=>   string(14) "139.129.150.40"   ["SERVER_ADMIN"]=>   string(32) "webmaster@qxu1780990217.my3w.com"   ["SERVER_NAME"]=>   string(22) "qxu1780990217.my3w.com"   ["SERVER_PORT"]=>   string(2) "80"   ["SERVER_PROTOCOL"]=>   string(8) "HTTP/1.1"   ["SERVER_SIGNATURE"]=>   string(0) ""   ["SERVER_SOFTWARE"]=>   string(6) "Apache"   ["UNIQUE_ID"]=>   string(24) "Wt8iggqjzDYAADQ3dj4AAAAK"   ["ORIG_PATH_INFO"]=>   string(11) "/brand.html"   ["ORIG_PATH_TRANSLATED"]=>   string(40) "/usr/home/qxu1780990217/htdocs/index.php"   ["PHP_SELF"]=>   string(10) "/index.php"   ["REQUEST_TIME_FLOAT"]=>   float(1524572802.4798)   ["REQUEST_TIME"]=>   int(1524572802) }      复制代码       发现并没有PATH_INFO，但是有一个ORIG_PATH_INFO         4、查找php手册，发现 'ORIG_PATH_INFO'     Original version of 'PATH_INFO' before processed by PHP. 复制代码       即”ORIG_PATH_INFO“是“PATH_INFO”在被PHP处理之前的版本。         5、最终解决办法 if ( !isset($_SERVER['PATH_INFO']) && isset($_SERVER['ORIG_PATH_INFO']) ) $_SERVER['PATH_INFO'] = $_SERVER['ORIG_PATH_INFO']; 复制代码完美！
