imagecreatefrombmp用PHP讀取BMP

Minimum spanning tree用PHP寫

<?php
    class Edge
    {
        public $v1;
        public $v2;
        public $weight;

        }
    }
   
    class Vertex

        public $name;

        function Vertex($name)
        {

        function create()
        {
               //create

        function edge_sort()

            usort($this->all_edge, "cmp");

1.目前IAR 8051 7.60 dirver還未支援windows 7 64bits
不過已經支援windows 7 32bits

2.版本對應
IAR 8051 7.50 → ZStack 1.4.3 → CC2430(已停產)
IAR 8051 7.51(未支援windwos 7) → ZStack 2.3.1 → CC2530
IAR 8051 7.60 → ZStack 2.4.0 → CC2530
~~IAR如果是下載完整版的可以用舊的keyreg破解~~
~~windows 7 開啟keyreg需要用管理員的權限開不然會錯~~

3.要是你是用windows 7 64bits 需要另外下載dirver
http://www.ti.com/lit/zip/swrc212

4.安裝完ZStack他的專案檔案是放在
C:\Texas Instruments\版本+硬體\Projects\zstack\Samples\SampleApp\硬體\SampleApp.eww
開啟編譯下載即可

CodeIgniter安裝

1.codeigniter 下載 http://codeigniter.com/

2.檔案裡面有
codeigniter_版本號碼
└┬application-你撰寫存放的地方
├system-系統核心的地方(最好不要修改)
├user_guide-說明書
├index.php-設定基本參數
└license.txt-權利書

3.將application、system、index.php複製到網頁目錄

4.設定rewrite
linux:

a2enmod rewrite

windows:
修改apache的httpd.conf將

#LoadModule rewrite_module modules/mod_rewrite.so

前面的#去掉

設定完成都要重新啟動apache

5.建立.htaccess
linux:
直接在跟index.php同層打 vi .htaccess
輸入下面code存檔即可
windows:
因為windows不支援沒檔名的檔案創立
所以在application或是在system裡面都有此檔案
複製到跟index.php同層
用筆記本開起編輯

將.htaccess
內容編輯為

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    # Submitted by: ElliotHaughin

    ErrorDocument 404 /index.php
</IfModule>

RewriteBase / 要設定為你放在跟目錄哪裡
例如:你開啟網頁的網址為http://localhost/index.php
那就是RewriteBase /
要是網址為http://localhost/CI/index.php
就要改成RewriteBase /CI/

RewriteCond %{REQUEST_URI} ^system.*
RewriteCond %{REQUEST_URI} ^application.*
是用來保護程式的假設你資料夾名稱有改
上面的名稱也要改
這樣才會保護到你的程式

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
是用來判斷是否有資料夾或是資料
例如:你在網址打http://localhost/css/
你下面沒有css的資料夾他就會導向其他地方
假設下面有css的資料夾他就不會導向

RewriteRule ^(.*)$ index.php?/$1 [L]
將RewriteBase後面的所有東西
都導向index.php?
例如: http://localhost/CI/welcome
在系統裡面就會變成 http://localhost/CI/index.php?/welcome
外面仍然是http://localhost/CI/welcome

6.設定config.php
放在application→config
將config.php裡面修改

$config['base_url']    = 'http://localhost/';

改成你自己的domain name
有放在目錄下要加上去
$config['index_page'] = 'index.php';
將index.php去除

7.設定database.php
放在application→config
將config.php裡面修改

$db['default']['hostname'] = 'localhost';//databaase的位置

$db['default']['username'] = 'root';//帳號
$db['default']['password'] = 'root123';//密碼
$db['default']['database'] = '';//資料庫名稱
$db['default']['dbdriver'] = 'mysql';//資料庫類型

8.開啟網頁
首先先輸入正常的跟目錄網址
要是看到跟下面一樣的圖
就是成功一半了

接下來就在和後面加上welcome也是跟下面一樣代表就是安裝成功了

linux SVN server + manager

需求：

linux + apache2 + php5 + mysql5

檔案下載：

Svnmanager →http://svnmanager.sourceforge.net/

安裝：

首先安裝Subversion

apt-get install subversion libapache2-svn

安裝pear的VersionControl_SVN

pear install -f -o VersionControl_SVN

PS:要是出現The program 'pear' is currently not installed. You can install it by typing: apt-get install php-pear 請安裝pear
apt-get install php-pear

將所下載的Svnmanager解壓縮到網頁的網址底下

將裡面的config.php.linux改名成config.php

建立2個檔案和2個資料夾

mkdir /var/svn
mkdir /var/svn/reops 
touch /var/svn/htpasswd
touch /var/svn/accessfile

設定資料夾和檔案全限為apache可以控制

chown -R www-data.www-data /var/svn/
chown -R www-data.www-data /var/svn/reops/ 
chown -R www-data.www-data /var/svn/htpasswd
chown -R www-data.www-data /var/svn/accessfile

設定apache2中的svn

vi /etc/apache2/mods-enabled/dav_svn.conf

修改為

<Location /svn>
  DAV svn
    AuthType Basic
    AuthName "Subversion Repository"
    SVNParentPath /var/svn/repos
    AuthUserFile /var/svn/htpasswd
    AuthzSVNAccessFile /var/svn/accessfile
    Require valid-user
</Location>

重啟apache2

/etc/init.d/apache restart

設定Svnmanager的config

vi config.php

將裡面修改成下面一樣

$svn_config_dir = "/var/svn/reops";
$svn_repos_loc = "/var/svn/reops";
$svn_passwd_file = "/var/svn/htpasswd";
$svn_access_file  = "/var/svn/accessfile";

$dsn = "mysqli://root:root@localhost/svn";

PS:mysqli後面為帳號:密碼@網址/資料庫名稱

建立資料庫

mysql -u root -p

鍵入SQL

CREATE DATABASE svn;
 
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER on svnmanager.* to svnmanager identified by 'secret';
 
FLUSH PRIVILEGES;

開啟網頁

在開啟一次輸入預設管理帳號密碼

帳號:admin
密碼:admin

創立第一個管理者帳號

PS:創立完畢admin就失效，請一定要勾選Admin

創立專案

設定使用者權限
