验证ImageMagick安装

Question

我的网络托管称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中我可以验证安装？

Answer 1

这是最简单和最好的：

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

Answer 2

试试这个：

<?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); 
?>

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扩展程序工作，我将此代码段粘贴到Web可访问文件中

<?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;
?>

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
}

Answer 5

在bash中：

$ convert -version

或

$ /usr/local/bin/convert -version

无需编写任何PHP文件只是为了检查。

Answer 6

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......

这在我的Godaddy托管上找到了所有版本。

将此文件上传到您的服务器并将其命名为ImageMagick.php或其他内容然后运行它。您将获得所需的所有信息......希望......

祝你好运。

<?
/*
// This file will run a test on your server to determine the location and versions of ImageMagick. 
//It will look in the most commonly found locations. The last two are where most popular hosts (including "Godaddy") install ImageMagick.
//
// Upload this script to your server and run it for a breakdown of where ImageMagick is.
//
*/
echo '<h2>Test for versions and locations of ImageMagick</h2>';
echo '<b>Path: </b> convert<br>';

function alist ($array) {  //This function prints a text array as an html list.
    $alist = "<ul>";
    for ($i = 0; $i < sizeof($array); $i++) {
        $alist .= "<li>$array[$i]";
    }
    $alist .= "</ul>";
    return $alist;
}

exec("convert -version", $out, $rcode); //Try to get ImageMagick "convert" program version number.
echo "Version return code is $rcode <br>"; //Print the return code: 0 if OK, nonzero if error.
echo alist($out); //Print the output of "convert -version"
echo '<br>';
echo '<b>This should test for ImageMagick version 5.x</b><br>';
echo '<b>Path: </b> /usr/bin/convert<br>';

exec("/usr/bin/convert -version", $out, $rcode); //Try to get ImageMagick "convert" program version number.
echo "Version return code is $rcode <br>"; //Print the return code: 0 if OK, nonzero if error.
echo alist($out); //Print the output of "convert -version"

echo '<br>';
echo '<b>This should test for ImageMagick version 6.x</b><br>';
echo '<b>Path: </b> /usr/local/bin/convert<br>';

exec("/usr/local/bin/convert -version", $out, $rcode); //Try to get ImageMagick "convert" program version number.
echo "Version return code is $rcode <br>"; //Print the return code: 0 if OK, nonzero if error.
echo alist($out); //Print the output of "convert -version";

?>

Answer 7

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，您可以找到安装的版本以及使用位置：

<?php
echo "<pre>";
system("type -a convert");  
echo "</pre>";
?> 

Answer 8

在Bash中，您可以检查Imagick是否已安装模块：

$ php -m | grep imagick

如果响应为空，则未安装。

Answer 9

要仅测试IMagick PHP扩展（而不是完整的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";

请记住，在安装Imagick（或实际上任何PHP模块）之后，您需要重新启动Web服务器和/或php-fpm（如果正在使用），以使该模块出现在phpinfo（）中。
