php 致命错误：找不到“imagick”类

Fatal error: Class 'imagick' not found

提问by Dev DOS

I am trying to install imagemagicphp extension under WampServer 2.

我正在尝试在 WampServer 2 下安装imagemagicphp 扩展。

• I've downloaded and installed ImageMagick . I've chosen ImageMagick-6.8.8-10-Q16-x86-dll.exe

• I've downloaded the php extension.

• I've moved the dll extension I just downloaded to C:\wamp\bin\php\php5.4.16\ext\

• I've altered php.ini (accessed it through wamp tray icon > right-click > PHP > php.ini) and added "extension=php_imagick.dll", without the quotes, to the extensions lists.

• I restarted Apache. Not noticing the extension displayed on the PHP extensions list from the tray icon, I restarted the wampserver. ImageMagick extensions now shows enabled on the list.

• 我已经下载并安装了 ImageMagick 。我选择了 ImageMagick-6.8.8-10-Q16-x86-dll.exe

• 我已经下载了 php 扩展。

• 我已经将刚刚下载的 dll 扩展移到 C:\wamp\bin\php\php5.4.16\ext\

• 我已经更改了 php.ini（通过 wamp 托盘图标 > 右键单击​​ > PHP > php.ini 访问它）并将“extension=php_imagick.dll”（不带引号）添加到扩展列表中。

• 我重新启动了Apache。没有注意到托盘图标中 PHP 扩展列表上显示的扩展，我重新启动了 wampserver。ImageMagick 扩展现在在列表中显示已启用。

However, I cannot use it. Doing a quick test returns "Fatal error: Class 'Imagick' not found". In the phpinfo() shows only that the imagemagick has been added to env variables.

但是，我无法使用它。进行快速测试会返回“致命错误：未找到‘Imagick’类”。在 phpinfo() 中仅显示 imagemagick 已添加到 env 变量中。

when I try to test the imagick :

当我尝试测试 imagick 时：

$im = new imagick( 'test.jpg' );
// resize by 200 width and keep the ratio
$im->thumbnailImage( 200, 0);
 // write to disk
$im->writeImage( 'test_thumbnail.jpg' );

I get the error:Fatal error: Class 'imagick' not foundWhat am I doing wrong? I'm working with win7 32 bit, phph 5-4-16 and apache2

我收到错误消息：Fatal error: Class 'imagick' not found我做错了什么？我正在使用 win7 32 位、phph 5-4-16 和 apache2

The only way that I make it works is by using an older version of imagick:php_imagick-3.2.0b1-5.4-nts-vc9-x86.

我让它工作的唯一方法是使用旧版本的 imagick: php_imagick-3.2.0b1-5.4-nts-vc9-x86。

• Try: php -m | grep imagick.
• If the result is empty do: sudo apt-get remove --purge php5-imagick && sudo apt-get install php5-imagick

• 试试：php -m | grep imagick。
• 如果结果为空，请执行以下操作： sudo apt-get remove --purge php5-imagick && sudo apt-get install php5-imagick

You might be having mis-aligned library versions.

您可能有未对齐的库版本。

Here's how I solved it

这是我解决的方法

I had really struggled with all these answers. Looking back I realised most of them are correct except they leave out some very finedetails that are crucial.

我真的为所有这些答案而挣扎。回顾过去，我意识到他们中的大多数都是正确的，只是他们遗漏了一些非常重要的细节。

1).First and foremost, before you start downloading any libraries or DLLs you want to start with your php_infoto find out these three very important parameters.

1）。首先，在您开始下载任何库或 DLL 之前，您要从 php_info开始找出这三个非常重要的参数。

Run the PHP_Info and check:

运行 PHP_Info 并检查：

1. Architecture : x86 or x64. Your computer might be x64 but your php is running on x86 so don't assume
2. Thread Safety : yes or no. Also very important.
3. Your PHP Version

1. 架构：x86 或 x64。您的计算机可能是 x64，但您的 php 在 x86 上运行，所以不要假设
2. 线程安全：是或否。也非常重要。
3. 您的 PHP 版本

2).Download ImageMagick from: https://windows.php.net/downloads/pecl/deps/. My computer is x64 but my php is running x86 so I downloaded ImageMagick-7.0.--vc*-x86.zip

2）。从以下位置下载 ImageMagick：https: //windows.php.net/downloads/pecl/deps/。我的电脑是 x64，但我的 php 运行的是 x86，所以我下载了 ImageMagick-7.0。--vc*-x86.zip

3).Unzip and copy all DLLs from the unzipped bin subfolder to the Apache bin directory. It's a bunch of CORE_RL_.dll and IM_MOD_RL_.dll plus a few other DLLs. In my case, [zippeddownload]/bin/* ->copied to -> C:\Xampp\apache\bin

3）。解压缩所有 DLL 并将其从解压缩的 bin 子文件夹复制到 Apache bin 目录。它是一堆 CORE_RL_ .dll 和 IM_MOD_RL_.dll 加上一些其他 DLL。就我而言，[zippeddownload]/bin/* -> 复制到 -> C:\Xampp\apache\bin

4).Go to http://pecl.php.net/package/imagick. You can select the zip link or just the DLL link. I prefer the DLL link. In my case I selected latest version 3.4.3. Which then took me to https://pecl.php.net/package/imagick/3.4.3/windows. Here we have to make another careful choice

4）。转到http://pecl.php.net/package/imagick。您可以选择 zip 链接或仅选择 DLL 链接。我更喜欢 DLL 链接。就我而言，我选择了最新版本 3.4.3。然后带我到https://pecl.php.net/package/imagick/3.4.3/windows。到这里我们又要慎重选择了

1. My php version is PHP 5.6
2. Thread Safety is enabled
3. Architecture php is running on is x86
4. So I took 5.6 Thread Safe (TS) x86

1. 我的 php 版本是PHP 5.6
2. 线程安全已启用
3. 正在运行的架构 php 是x86
4. 所以我拿了5.6 线程安全 (TS) x86

5).Unzip and copy "php_imagick.dll" to the php extfolder. And all other DLL files to the php folder

5）。解压并复制“php_imagick.dll”到 php ext文件夹。和所有其他 DLL 文件到 php 文件夹

6).Using an editor open php.ini. Search for "extension=" and add this line extension=php_imagick.dllas one of them.

6). 使用编辑器打开php.ini。搜索“extension=”并将这一行extension=php_imagick.dll添加为其中之一。

7).Restart Xampp/Wamp or just restart Apache and run PHP_INFO again. Imagick should display. If you still can't see it refer to this link http://php.net/manual/en/imagick.setup.php#119084

7）。重新启动 Xampp/Wamp 或只是重新启动 Apache 并再次运行 PHP_INFO。Imagick 应该显示。如果您仍然看不到它，请参阅此链接http://php.net/manual/en/imagick.setup.php#119084

Bonus tip:You might need to download visual c++ 14 runtime. From this link https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloadsI chose the latest version.

额外提示：您可能需要下载visual c++ 14 runtime。从这个链接https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads我选择了最新版本。

回答by Paulo Amaral

Did you try using the proper casing for the class, starting with capital "i"?

您是否尝试为类使用正确的大小写，以大写“i”开头？

$im = new Imagick( 'test.jpg' );

In php, class and files names and not case-sensitive, but classloaders are.

在 php 中，类和文件名不区分大小写，但类加载器是。

回答by earnest

do a <?php phpinfo(); ?>in any page. This will show all the services running on the service. If it is running then it will show you in which directory.

<?php phpinfo(); ?>在任何页面上做一个。这将显示在该服务上运行的所有服务。如果它正在运行，那么它将显示在哪个目录中。

If you are using WHM panel you might have to install imageMagick there

如果您使用 WHM 面板，您可能需要在那里安装 imageMagick
