PHP中获取当前页面的URL+tar压缩/解压+centos7修改中文字符集

javascript实现：

top.location.href   顶级窗口的地址this.location.href  当前窗口的地址

PHP实现

#测试网址:     http://localhost/blog/testurl.php?id=5//获取域名或主机地址 echo $_SERVER['HTTP_HOST']."<br>"; #localhost//获取网页地址 echo $_SERVER['PHP_SELF']."<br>"; #/blog/testurl.php//获取网址参数 echo $_SERVER["QUERY_STRING"]."<br>"; #id=5//获取用户代理 echo $_SERVER['HTTP_REFERER']."<br>"; //获取完整的urlecho 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING'];#http://localhost/blog/testurl.php?id=5//包含端口号的完整urlecho 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; #http://localhost:80/blog/testurl.php?id=5//只取路径$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"]; echo dirname($url);#http://localhost/blog

#压缩
tar -czvf ***.tar.gz
tar -cjvf ***.tar.bz2
#解压缩

tar -xjvf ***.tar.bz2

CentOS 7字符集的问题与6有点区别，会出现下面问题，查看是中文，vi进入就变成乱码了

修改配置文件

[root@ce1d2002a999 ~]# cat /etc/locale.conf LANG="zh_CN.UTF-8"

改为中文字符集

然后在查看更改后的系统语言变量

[root@5c46832b5c01 ~]# localelocale: Cannot set LC_CTYPE to default locale: No such file or directorylocale: Cannot set LC_MESSAGES to default locale: No such file or directorylocale: Cannot set LC_ALL to default locale: No such file or directoryLANG=zh_CN.UTF-8LC_CTYPE="zh_CN.UTF-8"LC_NUMERIC="zh_CN.UTF-8"LC_TIME="zh_CN.UTF-8"LC_COLLATE="zh_CN.UTF-8"LC_MONETARY="zh_CN.UTF-8"LC_MESSAGES="zh_CN.UTF-8"LC_PAPER="zh_CN.UTF-8"LC_NAME="zh_CN.UTF-8"LC_ADDRESS="zh_CN.UTF-8"LC_TELEPHONE="zh_CN.UTF-8"LC_MEASUREMENT="zh_CN.UTF-8"LC_IDENTIFICATION="zh_CN.UTF-8"LC_ALL=

查看语言包

[root@5c46832b5c01 ~]# locale -alocale: Cannot set LC_CTYPE to default locale: No such file or directorylocale: Cannot set LC_MESSAGES to default locale: No such file or directorylocale: Cannot set LC_COLLATE to default locale: No such file or directoryCPOSIXen_US.utf8

发现没有中文，安装一个，注意7跟6不一样

# yum install kde-l10n-Chinese#yum reinstall glibc-common

再次查看

[root@ce1d2002a999 ~]# cat test  我的意思是[root@ce1d2002a999 ~]# vi test 我的意思是

更改完毕！！
