Verify ImageMagick installation
提问by Desmond Liang
My web hosting said ImageMagic has been pre-installed on the server. I did a quick search for "ImageMagick" in the output of phpinfo() and I found nothing. I can't SSH in the server so is there a way in PHP I can verify the installation?
我的虚拟主机说 ImageMagic 已预装在服务器上。我在 phpinfo() 的输出中快速搜索了“ImageMagick”，但一无所获。我无法在服务器中使用 SSH，所以在 PHP 中有一种方法可以验证安装吗？

Try this:
尝试这个：
<?php
//This function prints a text array as an html list.
function alist ($array) {
$alist = "<ul>";
for ($i = 0; $i < sizeof($array); $i++) {
$alist .= "<li>$array[$i]";
}
$alist .= "</ul>";
return $alist;
}
//Try to get ImageMagick "convert" program version number.
exec("convert -version", $out, $rcode);
//Print the return code: 0 if OK, nonzero if error.
echo "Version return code is $rcode <br>";
//Print the output of "convert -version"
echo alist($out);
?>

This is as short and sweet as it can get:
这是尽可能简短和甜蜜的：
if (!extension_loaded('imagick'))
echo 'imagick not installed';

EDIT: The info and script below only applies to iMagick class - which is not added by default with ImageMagick!!!
编辑：下面的信息和脚本仅适用于 iMagick 类 - 默认情况下不会添加 ImageMagick ！！！
If I want to know if imagemagick is installed and actually working as a php extension, I paste this snippet into a web accessible file
如果我想知道 imagemagick 是否已安装并实际用作 php 扩展，我将此代码段粘贴到可访问的网络文件中
<?php
error_reporting(E_ALL);
ini_set( 'display_errors','1');
/* Create a new imagick object */
$im = new Imagick();
/* Create new image. This will be used as fill pattern */
$im->newPseudoImage(50, 50, "gradient:red-black");
/* Create imagickdraw object */
$draw = new ImagickDraw();
/* Start a new pattern called "gradient" */
$draw->pushPattern('gradient', 0, 0, 50, 50);
/* Composite the gradient on the pattern */
$draw->composite(Imagick::COMPOSITE_OVER, 0, 0, 50, 50, $im);
/* Close the pattern */
$draw->popPattern();
/* Use the pattern called "gradient" as the fill */
$draw->setFillPatternURL('#gradient');
/* Set font size to 52 */
$draw->setFontSize(52);
/* Annotate some text */
$draw->annotation(20, 50, "Hello World!");
/* Create a new canvas object and a white image */
$canvas = new Imagick();
$canvas->newImage(350, 70, "white");
/* Draw the ImagickDraw on to the canvas */
$canvas->drawImage($draw);
/* 1px black border around the image */
$canvas->borderImage('black', 1, 1);
/* Set the format to PNG */
$canvas->setImageFormat('png');
/* Output the image */
header("Content-Type: image/png");
echo $canvas;
?>

Try this one-shot solution that should figure out where ImageMagick is, if you have access to it...
试试这个一次性解决方案，它应该找出 ImageMagick 在哪里，如果你可以访问它......
This found all versions on my Godaddy hosting.
这在我的 Godaddy 主机上找到了所有版本。
Upload this file to your server and call it ImageMagick.phpor something then run it. You will get all the info you need... hopefully...
将此文件上传到您的服务器并调用它ImageMagick.php或其他东西然后运行它。你会得到你需要的所有信息......希望......
Good luck.
祝你好运。

In Bash you can check if Imagick is an installed module:
在 Bash 中，您可以检查 Imagick 是否已安装模块：
$ php -m | grep imagick
If the response is blank it is not installed.
如果响应为空白，则表示未安装。

If your ISP/hosting service has installed ImageMagick and put its location in the PATH environment variable, you can find what versions are installed and where using:
如果您的 ISP/托管服务已安装 ImageMagick 并将其位置放在 PATH 环境变量中，您可以找到安装了哪些版本以及在何处使用：
<?php
echo "<pre>";
system("type -a convert");
echo "</pre>";
?>

To test only the IMagick PHP extension (not the full ImageMagick suite), save the following as a PHP file (testImagick.php) and then run it from console: php testImagick.php
要仅测试 IMagick PHP 扩展（不是完整的 ImageMagick 套件），请将以下内容另存为 PHP 文件 (testImagick.php)，然后从控制台运行它： php testImagick.php
<?php
$image = new Imagick();
$image->newImage(1, 1, new ImagickPixel('#ffffff'));
$image->setImageFormat('png');
$pngData = $image->getImagesBlob();
echo strpos($pngData, "\x89PNG\r\n\x1a\n") === 0 ? 'Ok' : 'Failed';
echo "\n";
