PHP jquery ajax 提交登录

query ajax代码：

        return false;
    });
});
function login() {
var user = $("#username").val();

PHP之Emacs实现自动提示

这里主要感谢“土豆”兄弟提供的一个日本emacser 的博客网站地址，在哪里看到详细的配置，我也是按照步骤配置的，结果成功了。不过还需要改进，有点别扭，

得知此配置的网站：http://d.hatena.ne.jp/IMAKADO jump

首先将这个文件download下来，放在一个路径里面。我的就放在 ~/.emacs.d/php/下面

wget http://www.emacswiki.org/cgi-bin/wiki/download/install-elisp.el

将此文件加载到配置文件中去。
(add-to-list 'load-path "~/.emacs.d/php/")
(require 'install-elisp)
(setq install-elisp-repository-directory "~/.emacs.d/php/");;设置使用install-elisp-from-emacswiki 后下载下来的文件路径，我把它们放在一个文件夹里面

然后使用M-x将相关的文件get download下来，不用管它会怎么样，因为我们设置了下载路径，自动会下载到那个路径文件夹里面。（* 注意，Pagename输入后 他会自动打开，你需要执行C-c C-c 进行编译。）
M-x:
install-elisp-from-emacswiki
Pagename:
anything.el
M-x:
install-elisp-from-emacswiki
Pagename:
anything-match-plugin.el
M-x:
install-elisp-from-emacswiki
Pagename:
auto-complete.el


;;完成后在.emacs 加入此句代码 :

(locate-library "auto-complete.el")

;;然后重新载入下.emacs 文件。跟前面的操作一样，我们的PHP配置文件给弄下来编译。
M-x:
install-elisp-from-emacswiki
Pagename:
php-completion.el

;;php 自动提示设置

(add-hook 'php-mode-hook
(lambda()
(require 'php-completion)
(php-completion-mode t)
(define-key php-mode-map (kbd "C-c p") 'phpcmp-complete)
(when (require 'auto-complete nol t)
(make-variable-buffer-local 'ac-sources)
(add-to-list 'ac-sources 'ac-source-php-completion)
(auto-complete-mode t))))

强悍的HTML

HTML5 的 Canvas 对象将改变 JavaScript 的使命，使之成为 HTML5 下强大的动画脚本编写工具。本文介绍了 8 个你从未见过的，基于 HTML5 Canvas 和 JavaScript 的动画，这些令人难以置信的效果将使你对 HTML5 彻底折服。需要指出的是，这些都是浏览器的原生动画，无需任何插件。
Tunnelers

纯 JavaScript + HTML5 Canvas 生成的交互动画，难以置信。
The Mesmerizer

在格子中移动鼠标，颜色随着改变并扩散到周围的格子，很迷幻。用鼠标点四角的格子，或按键盘，可以看到更奇妙的效果。
Burn


在页面上移动鼠标，或按下鼠标，这样的效果，很难相信是浏览器原生的。
Cheloniidae Live

也是基于纯粹的 JavaScript，不过使用了一个 JavaScript 库。很有趣，你可以通过修改其 JavaScript 代码实现自己的效果（可惜被墙了）。
Canvas 3D engine

一个基于 Canvas 的 3D 引擎。目前只支持预设的图形，纹理及基本交互功能。
Bomomo

很值得一试。
DDD

这个交互动画也很有趣。
Plasma Tree

非常阿凡达。

用php中的popen函数实现php的并发处理

用php中的popen函数实现php的并发处理:当我们需要调用一个比较耗时外部资源时使用popen这个函数， 最常见的就是从外部API获取相关内容.使用方法：
1. 建立外部资源脚本。 如示例中使用t.sh。 当然， 也可以直接使用curl等命令行2. 准备好参数， 提供给pipe脚本
2. 使用popen调用脚本。 调用之后，就不用关心了。
3. 开始其他的和pipe不相关的逻辑处理
4. 其他处理完成之后， 使用fgets等方式，
获取popen的数据
php程序：
# get argument for pipe here if it has.
#start pipe
echo ’call popen start: ’. date("H:i:s"), "\n";
$pipe = popen(dirname(__FILE__) . ’/t.sh’, ’r’);
echo ’call popen end: ’. date("H:i:s"), "\n";
#Other code here
sleep(5);
echo "Here is my code. time: " . date("H:i:s"), "\n";
#read pipe result
while ($s = fgets($pipe,1024)) {
echo $s;
}
pipe脚本：
echo 1, `date +%T`;
sleep 1;
echo 2, `date +%T`;
sleep 10;
echo 3, `date +%T`;
输出结果：
call popen start: 10:16:40
call popen end: 10:16:40
Here is my code. time: 10:16:451, 10:16:402, 10:16:413, 10:16:51
结论， 我们有三个sleep。
php中一个 sleep 5,sh中两个sleep， 10+1如果使用串行的方式， 那么用时应该是10+1+5 ＝ 16秒。而使用pipe方式， 用时仅为：max(php, pipe) = max(5,11) = 11秒。

纯 CSS3 实现的 Twitter 图画

上过 Twitter 的人都知道下面的这幅图片，这是 Twitter 的出错画面。一位叫 Steve Dennis 的新西兰 Web 前端设计师，使用纯 CSS 生成了这幅画面，甚至，假如你使用基于 Webkit 的浏览器（Safari 或 Chrome），画面还可以动，不过，对 IE 浏览器，生成的效果还差强人意。

作者的灵感来自 Twitter 的一次宕机，当 Twitter 页面上出现这个画面，他突发奇想，希望用 CSS 生成一幅同样的图画，并加上动画效果。

如何实现

事实上很不容易，纯手工编码，不断的试验与失败。曲线使用 CSS 的圆角功能，复杂线条则使用容器遮罩，花了一个周末，很有趣，但不想再尝试第二回。

在 IE 里怎么样

以下是在 IE8 里面生成的效果截图，差强人意。

反馈

作者的博客中，获得了百余条反馈，有人提到在 iPhone 中显示有些问题，但在 Android 中显示很完美。但无一例外都对这一 CSS 作品表现出由衷的敬意，也有人提到用 SVG 实现更容易，不过，这一工作的意义在于对 CSS 的能力进行一次残酷测试，看来 CSS 挺过来了，虽然过程有些痛苦。

迅雷专用链接原理及转换

对于迅雷专用链接不用我去解释相信大家都明白（别告诉我你不懂~汗），现在就链接的编码原理及转换详细说明一下，明白以后就可以用迅雷下载快车、旋风专用 地址的软件啦。

首先要明白Base64编码是怎么一回事，不懂的先去百度一下再回来。
Base64编码是一种加密算 法，Email的原始信息就是由Base64编码构成的。
而这些专用链接都是通过Base64编码加工转换而成的。

迅雷专用 地址例子：thunder://QUFodHRwOi8vZG93bi5pcHZ2LmNuL3diLmV4ZVpa
真实文件下载链 接：http://down.ipvv.cn/wb.exe

附转换工具下载：http://ifu25.cn /VC_down.asp?FileName=ChangeRUL.rar

搞懂了Base64编码之后，一切都变的得心应手了：

实 例原始地址：http://im.baidu.com/install/BaiduHi.exe

1、迅雷专用链接编码

在 原地址前面加"AA"，后面加"ZZ"(不包括引号)，地址变为

AAhttp://im.baidu.com/install/BaiduHi.exeZZ

此地址base64编码为

QUFodHRwOi8vaW0uYmFpZHUuY29tL2luc3RhbGwvQmFpZHVIaS5leGVaWg==

迅雷专链即在上地址前加thunder://，即

Thunder://QUFodHRwOi8vaW0uYmFpZHUuY29tL2luc3RhbGwvQmFpZHVIaS5leGVaWg==
2、快车专用链接编码

在原地址前后都加上"[FLASHGET]"(不包括引号)，地址变为

[FLASHGET]http://im.baidu.com/install/BaiduHi.exe[FLASHGET]

此地址base64编码为

W0ZMQVNIR0VUXWh0dHA6Ly9pbS5iYWlkdS5jb20vaW5zdGFsbC9CYWlkdUhpLmV4ZVtGTEFTSEdFVF0=&yinbing1986

快车专链即在上地址前加flashget://，注意后面还要加上"&符号"，符号怎么得出不清楚，在最后后面加的是好好爱的 个人信息，至今未有人报告转换错误，即

Flashget://W0ZMQVNIR0VUXWh0dHA6Ly9pbS5iYWlkdS5jb20vaW5zdGFsbC9CYWlkdUhpLmV4ZVtGTEFTSEdFVF0=&yinbing1986

3、旋风专用链接编码

旋风相对就简单多了，将原地址直接base64编码为

aHR0cDovL2ltLmJhaWR1LmNvbS9pbnN0YWxsL0JhaWR1SGkuZXhl

旋风专链即在上地址前加qqdl://，即

qqdl://aHR0cDovL2ltLmJhaWR1LmNvbS9pbnN0YWxsL0JhaWR1SGkuZXhl
