验证ImageMagick安装

我的网站托管说ImageMagic已预先安装在服务器上.我在phpinfo()的输出中快速搜索了"ImageMagick",但我什么都没发现.我不能在服务器上SSH,所以有没有办法在PHP我可以验证安装？

这是短暂而甜蜜的:

if (!extension_loaded('imagick'))
    echo 'imagick not installed';

试试这个:

";
  for ($i = 0; $i < sizeof($array); $i++) {
    $alist .= "
$array[$i]";
  }
  $alist .= "";
  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 $rcode 
"; 
//Print the output of "convert -version"    
echo alist($out); 
?>

如果安装了ImageMagick应用程序,则测试,而不是PHP模块

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!

如果我想知道imagemagick是否已安装并且实际上是作为php扩展工作,我将此片段粘贴到Web可访问文件中

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;
?>

你应该看到一个hello world图形:

您可以在PHP中轻松检查Imagick类.

if( class_exists("Imagick") )
{
    //Imagick is installed
}

---

**important:**有时这会返回FALSE但是`extension_loaded('imagick')`返回TRUE!所以我想更好的是:`if(extension_loaded('imagick')|| class_exists("Imagick")){/*做想象*/}`

在bash中:

$ convert -version

要么

$ /usr/local/bin/convert -version

无需编写任何PHP文件即可查看.

---

只是为了省去别人的麻烦-转换是imagick安装的shell命令，因此上述内容直接与其进行了交谈，以检查它是否在其中+1

试试这个一次性解决方案应该找出ImageMagick的位置,如果你有权访问它...

这发现我的Godaddy托管上的所有版本.

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.您将获得所需的所有信息......希望......

祝好运.
