windows7下安装php的imagick和imagemagick扩展教程_PHP
最近的PHP项目中,需要用到切图和缩图的效果,在linux测试服务器上很轻松的就安装好php imagick扩展。但是在本地windows开发环境,安装过程遇到好多问题,在此与大家分享。
1. 下载 ImageMagick
下载地址:http://imagemagick.org/script/binary-releases.php#windows
下载最新版本,ImageMagick-6.8.6-9-Q16-x86-dll.exe
2. 安装 ImageMagick
安装 ImageMagick 到 PC 上。安装路径不能出现空格,否则无法使用。安装时,一点选中把执行路径添加到 path 上,否则你就得手动去添加 path 路径了。
3. 测试安装
打开windows 命令行窗口(win+r -> “cmd” -> Enter),输入convert,回车。会出现convert的帮助文档,如果没有出现,说明没有安装成功,或没有把安装目录添加到环境变量 path 中。
添加到环境变量,如我的 ImageMagick 安装目录是 c:/imagemagick。
添加过程:
我的电脑 -> 右键点击 -> 高级系统设置 -> 高级 -> 环境变量 -> 系统变量 -> path -> 选择并编辑 -> 把你的安装目录,添加到其中
4. 下载 php扩展 php_imagick.dll
php5.4.x or php5.5.x 下载地址 http://www.peewit.fr/imagick/
dyn = dynamic, st = static, q16 = 16 bit, q8= 8 bit.
以上标识,同你下载的ImageMagick下载标识相同,本人用的是q16
5. 把dll文件重命名为php_imagick.dll,并放到php 扩展文件目录 php/ext 中。
6. 在 php.ini 配置文件中添加,extension=php_imagick.dll。
7. 重启电脑,只重启apache不管用的情况下,重启下PC。因为扩展底层使用的是imageMagic软件,所以软件重启电脑,重新加载软件,并刷新path路径。
8. 重启后,打开 phpinfo页面,查看,扩展已经安装成功。如果还未安装成功,极有可能imagemagick软件版本过高,请选择更低一级的版本安装。
9. PHP测试代码。
<?php $im = new imagick( 'a.jpg' ); // resize by 200 width and keep the ratio $im->thumbnailImage( 200, 0); // write to disk $im->writeImage( 'a_thumbnail.jpg' );
10. 查看手册,学习API
相关扩展学习手册地址 http://uk3.php.net/manual/zh/book.imagick.php 手册中包含大量易用实例。
这里还有查看命令行参数的文档 http://www.imagemagick.org/Usage/

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
