vi/vim 注释字体颜色的设置
在vi中被注释掉的字体颜色默认为蓝色,无法看清,通过设置用户根目录下.vimrc文件,可以更改颜色的配置。
通过hi命令来修改注释的颜色,使用方法:
设置关键字为蓝色非粗体 :hi Identifier ctermfg =blue cterm=none (bold 就设置成粗体)

linux 打包压缩命令
tar命令
tar [-cxtzjvfpPN] 文件与目录
-c :建立一个压缩文件的参数指令(create 的意思);
-x :解开一个压缩文件的参数指令!
-t :查看 tarfile 里面的文件!
特别注意,在参数的下达中, c/x/t 仅能存在一个!不可同时存在!因为不可能同时压缩与解压缩。
-z :gzip
-j :bzip2
-v :压缩的过程中显示文件!这个常用,但不建议用在背景执行过程!
-f :使用档名,请留意,在 f 之后要立即接档名不要再加参数!
-p :使用原文件的原来属性(属性不会依据使用者而变)
-P :可以使用绝对路径来压缩!
-N :比后面接的日期(yyyy/mm/dd)还要新的才会被打包进新建的文件中!
--exclude FILE:在压缩的过程中,不要将 FILE 打包!
1、查看linux的内核版本,系统信息,常用的有四种办法:
uname -a
more /etc/issue
cat /proc/version
more /etc/redhat-release
2、nginx编译参数:
3、apache查看版本编译参数
apache版本:
httpd -v
apache编译参数:
4、查看php版本及编译参数
php编译参数:
php -v
5、查看mysql版本及参数
查看mysql版本:
mysql -v 或者是--help|grep Distrib来查看;
进入数据库
select version(); 或者status;或者/s;
mysql编译参数:

PHPCMS模板制作笔记
织梦dedecms中仅channel支持currentstyle属性,实际使用中往往需要channelartlist添加currentstyle,修改如下:
修改include\taglib\channelartlist.lib.php第93行$pv->Fields['typeurl'] = GetOneTypeUrlA($typeids[$i]);新增(其中'ON'为设置的样式类):
中文等多字节字符串翻转
$str = '字符串反转';
function rev($str, $encoding = 'utf-8'){
$len = mb_strlen($str, $encoding);
$result = '';
for ($i = $len-1; $i>=0; $i--){
$result.= mb_substr($str,$i,1,$encoding);
}
return $result;
}
echo rev($str);
生成圆形头像:
test('2.jpg','1.jpg'); #2原图 1生成图
function test($url,$path='./'){
$w = 100; $h=100; // original size
$original_path= $url;
$dest_path = $path.uniqid().'.png';
$src = imagecreatefromstring(file_get_contents($original_path));
$newpic = imagecreatetruecolor($w,$h);
imagealphablending($newpic,false);
$transparent = imagecolorallocatealpha($newpic, 0, 0, 0, 127);
$r=$w/2;
for($x=0;$x<$w;$x++)
for($y=0;$y<$h;$y++){
$c = imagecolorat($src,$x,$y);
$_x = $x - $w/2;
$_y = $y - $h/2;
if((($_x*$_x) + ($_y*$_y)) < ($r*$r)){
imagesetpixel($newpic,$x,$y,$c);
}else{
imagesetpixel($newpic,$x,$y,$transparent);
}
}
imagesavealpha($newpic, true);
imagepng($newpic, $dest_path);
imagedestroy($newpic);
imagedestroy($src);
// unlink($url);
return $dest_path;
}
