原文如下:附本人翻译(翻译水平其差,可以忽略直接看英文)

- I know, it's been a while since I last blogged. This is because a lot of things are happening in my personal life. I recently relocated to London from Finland and started a new job. Things are quite busy but I will try to post an example now and then. In the meanwhile I would like to hear about sites using Imagick, so if your project is not super secret please post an url and maybe a small explanation what you're doing with Imagick on the site. This is purely for my personal interest.
-
- Anyway, to the point. Today's example originates from a question asked by a user. How do I thumbnail the image inside given dimensions proportionally and fill the "blank" areas with a color? Well, the answer is here :)
-
- The code is for Imagick 2.1.0 but adapting to older versions should not be hard.
翻译如下:
我知道现在离我的博客更新有一段时间了,这主要是因为最近发生了很多事。最近我找了份新工作,使我从芬兰搬到了伦敦,工作也非常忙,所以我在这里仅仅只发一个示例。同时我很高兴听到很多网站使用了imagick,我也希望如果您的项目不是很保密的话,是否能够发个链接及少量的注释以说明您的站点是如何使用Imagek的。顺便说一声,这完全是我个人的兴趣。
OK,上重头菜。今天的例子起源于一个用户的问题,那就是如果在为一张图片按比例做缩略图的时候,怎么为留空的地方用其他颜色填充。这个例子就是我的回复。
代码是FOR ImagicK 2.1.0版本,当然要改成以前的老版本代码也不是件难事。
下面就是代码了:
PHP代码
- <?php
-
- /* 定义缩略图的长宽*/
- $width = 100;
- $height = 100;
-
- /*创建一个对象,同时读回源图*/
- $im = new Imagick( "test.png" );
-
-
- /*按照比例进行缩放*/
- $im->thumbnailImage( $width, $height, true );
-
- $canvas = new Imagick();
- $canvas->newImage( $width, $height, 'pink', 'png' );
-
- $geometry = $im->getImageGeometry();
-
- $x = ( $width - $geometry['width'] ) / 2;
- $y = ( $height - $geometry['height'] ) / 2;
-
- $canvas->compositeImage( $im, imagick::COMPOSITE_OVER, $x, $y );
-
- header( "Content-Type: image/png" );
- echo $canvas;
- ?>

虽然 LAMP 组合很不错,但是如果想要架设一台同时支持 PHP、ASP、ASP.NET、JSP、Perl 的 Web 虚拟主机服务器,还是用 Windows 2003 的 IIS 6 最好。网上有很多介绍在 IIS 6 上配置 PHP 的文章,但是那些方法不是性能不好,就是升级麻烦。下面的方法可以让你在第一次配置好后,能够非常方便的进行升级。
这里所说的升级,是指从某个 php4 版本升级到另一个 php4 版本,或者从某个 php5 版本升级到另一个 php5 版本,而不是指从 php4 升级到 php5。
准备:
一台安装好的 Windows 2003 服务器,并且已经安装了 IIS 6。
下载 Windows 版的 PHP 二进制压缩包。
安装:
解压缩 PHP 二进制压缩包到 C:\php 目录下(这里假设 C: 盘是系统盘,即安装了Windows 系统的盘,如果系统盘是 D: 盘,则解压缩到 D:\php 目录下,以此类推,下同)。
然后打开“我的电脑”->“属性”->“高级”->“环境变量”->“系统变量”->“path”,编辑其值,在前面增加下面的路径地址:
C:\php;C:\php\dlls;C:\php\extensions;C:\php\sapi;
将 php.ini-dist 或 php.ini-recommended 复制到 C:\Windows 目录下,并改名为 php.ini,一般正式发布网站的服务器用 php.ini-dist,而作为调试用的服务器用 php.ini-recommended 更好。当然一般情况下,这个 php.ini 还是需要根据实际情况来修改的。
下面来介绍一下几个必要的修改选项:
extension_dir = "C:\php\extensions"
这个是 PHP 扩展所放置的目录,请确保跟你实际安装的目录相同。
PHP常用扩展
- extension=php_mbstring.dll
- ;extension=php_big_int.dll
- extension=php_bz2.dll
- extension=php_cpdf.dll
- extension=php_crack.dll
- extension=php_curl.dll
- extension=php_db.dll
- extension=php_dba.dll
- extension=php_dbase.dll

上面这些,开头没有加分号的是打开的扩展,加了分号的是没有打开的扩展。上面的设置包含了在 Windows 2003 上默认安装情况下可以打开所有扩展(这里列出的是 php 4 的)。
session.save_path = b:\sessions
这个是 session 文件默认保存的目录,这个目录必须是一个存在的目录,不然默认的 session 功能会无效。我这里设置的是一个 ramdisk 上的一个目录。将 session.save_path 设置在 ramdisk 上可以加快 session 处理的速度。如果你没有安装 ramdisk,你可以把它指定到其他盘的任何一个目录下,如 C:\sessions 目录、C:\Windows\Temp 目录等。
OK,基本工作作完了,现在该配置 IIS 了。
打开“ Internet 信息服务(IIS)管理器”,在“ Web 服务扩展”里,选择“添加一个新的 Web 服务扩展”,扩展名可填写“PHP ISAPI 扩展”,要求的文件选择:C:\php\sapi\php4isapi.dll(如果安装的是 PHP5,则此处是 C:\php\sapi\php5isapi.dll,下同),并设置扩展状态为允许。
打开“网站”->“属性”->“主目录”->“应用程序设置”->“配置”->“应用程序扩展”->“添加 ”,可执行文件还是选择 C:\php\sapi\php4isapi.dll。扩展名填写“.php”,动作限制为“HEAD,GET,POST”。
打开“网站”->“属性”->“文档”->“启用默认内容文档”->“添加”,可以将 index.php 添加为默认内容文档。
然后选择“服务器机器名”->“所有任务”->“重新启动 IIS”来重启 IIS。
测试
在默认网站发布目录下,建立一个测试页面:
PHP代码
- <?php
- phpinfo();
- ?>
如果打开这个页面能够看到 php 安装配置信息,就算是安装成功了。
如果想要更优化的执行 php 程序,可以安装 ZendOptimizer-3.0.1-Windows-i386.exe,这个东西安装非常简单,这里就不介绍了。
升级
现在升级就非常简单了。只需要将新版本的 PHP 二进制压缩包下载下来,将原来的 C:\php 目录删除,将新版本解压缩到 C:\php 目录中,然后重新启动一下 IIS 就可以了。不需要修改任何配置,也不需要往 System32 目录中复制任何文件。是不是很方便啊?
膘叔的小技巧:
由于在IIS下面建立站点和关闭站点都比较方便,但是象上面说的升级就不是很方便了。我是指启用站点,虽然直接点击控制台上的restart按钮很方便,但。。。WINDOWS有时候会突然卡死,那时候是关也不能关,开也不能开,只能注销,在这里,我提供一个小小的批处理文件,只要放在桌面上,想重启的时候运行一下就行了。。
文件内容如下:
XML/HTML代码
- net stop w3svc
- net start w3svc
是不是很简单?但不要小看这两行,WINDOWS好象是对命令行的处理有一定的优先级,而且用命令行不会被卡死。

作者:andot,来自:www.coolcode.cn,出处:http://www.coolcode.cn/show-41-1.html
原文如下
- 昨天在调试 WAP 网站时发现,在增加了 GB2312 到 UTF-8 转化以后,有些页面显示不正常了——有些页面只有一半的内容,另一半被截掉了。因为被截掉的部分包含了<p>的后半个标签</p>,因此整个页面都显示不出来,而报告错误。经过猜测、尝试,最后终于把问题集中在了 iconv 函数上。在经过高人指点以后,发现这个函数的第二个参数,除了可以指定要转化到的编码以外,还可以增加两个后缀://TRANSLIT 和 //IGNORE,其中 //TRANSLIT 会自动将不能直接转化的字符变成一个或多个近似的字符,//IGNORE 会忽略掉不能转化的字符,而默认效果是从第一个非法字符截断。但是我尝试了//TRANSLIT 和 //IGNORE 这两个后缀,效果还是不对。于是我想问题可能不是出在这里。从 GB2312 到 UTF-8 转化应该不会有不能转化的字符,因为 UTF-8 的字符集完全包含了 GB2312 中的字符,所以我想大概是前面要转化的字符集指定错了,于是我尝试着把 GB2312 改成 GBK,问题解决!虽然那两个后缀在这里没派上用场,不过也算学了一招,以后肯定会用到的。补记:改成 GBK 后,发现仍然有一封邮件的内容解析不正确。在另一位高人指点下,先换成 GB18030,问题依旧,然后改用 mb_convert_encoding 进行转换,问题解决!不知道是 mb_convert_encoding 问题,还是我的系统问题,我用 mb_convert_encoding 时不支持 GB18030 编码。另外,用 GBK 或者GB18030 作为输入编码,并在输出编码中加上 //IGNORE 后缀,用 iconv 函数也能解决那封含有错误编码的邮件内容解析不正确的问题。不过用 mb_convert_encoding 可以指定多种输入编码,它会根据内容自动识别,这个比 iconv 要好的多。
其实,同事在生成图片文字水印的时候也遇到了这种问题,同事最初用的是GB2312字符集,结果直接报错,说是字符串的offset有问题,但仔细检查后却没有这种问题。后来才发现是直接调用的这个iconv转换出错了。
原来的转换是从gb2312往 UTF8转换,表面上确实没有什么问题,然而,现在的人特别爱装酷,受影响的那位同志,用的是繁体字,繁体字的字库大多情况是属于GBK的,所以后来换成GBK后就正常了。
估计以后再遇上用火星文的朋友,就真的只能使用andot提出的这种方法了。转换成18030,再使用ignore参数。哈哈
mbstring好象最初的版本里没有使用,如果换成这个,估计代码工作量非常大,先将就着点了

闲来无事,到coolcode.cn上去闲逛。发现了一些比较旧的文章,以前也都看过,但,那时候没有开博,所以也就没有记录。如今博客也开了,coolcode.cn估计要成为我搜刮的对象了。
coolcode.cn的作者是andot,PHPRPC的作者,我06年年中(应该没记错)就使用了这个软件,同年放弃使用xajax,当然,现在我更多的使用jquery来操作ajax,但PHPRPC的功能不完全局限于ajax,我这里就不详谈了。先谈这篇文章。。。
无耻的分隔线:
原来,在从 PHP 中直接传递字符串给 JavaScript 时,直接用了 addcslashes,如果传递的是带有 utf-8 编码汉字的,就用 "\0..\037\042\134",如果纯 ascii 范围内的字符串,就用 "\0..\037\042\134\177..\377"。但是今天在写加密程序时发现,发现程序有时行,有时不行。后来发现原来是 \v \a 搞的。addcslashes 会把 \007..\015(八进制) 转义成 \a\b\t\n\v\f\r,而其中 \a 这个 IE 和 Firefox 都不认识,\v 这个 Firefox 认识,IE 不认识。所以我写了下面这个函数,用它可以就可以转化成 JavaScript/JScript 所认识的字符串了(其中 $flag 表示是否转义 ascii 码大于 127 的字符)。感谢五帝同学的帮助!
PHP代码
-
- function addjsslashes($str, $flag = true)
- {
- if ($flag) {
- $str = addcslashes($str, "\0..\006\010..\012\014..\037\042\047\134\177..\377");
- }
- else {
- $str = addcslashes($str, "\0..\006\010..\012\014..\037\042\047\134");
- }
- return str_replace(
- array(chr(7), chr(11)),
- array('\007', '\013'),
- $str
- );
- }
