Verify ImageMagick installation
PhpImagemagickPhp Problem Overview
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?
Php Solutions
Solution 1 - Php
This is as short and sweet as it can get:
if (!extension_loaded('imagick'))
echo 'imagick not installed';
Solution 2 - Php
Try this:
<?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);
?>
Solution 3 - Php
EDIT: The info and script below only applies to iMagick class - which is not added by default with 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
<?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;
?>
You should see a hello world graphic:
Solution 4 - Php
In bash:
$ convert -version
or
$ /usr/local/bin/convert -version
No need to write any PHP file just to check.
Solution 5 - Php
You can easily check for the Imagick class in PHP.
if( class_exists("Imagick") )
{
//Imagick is installed
}
Solution 6 - Php
In Bash you can check if Imagick is an installed module:
$ php -m | grep imagick
If the response is blank it is not installed.
Solution 7 - Php
Try this one-shot solution that should figure out where ImageMagick is, if you have access to it...
This found all versions on my Godaddy hosting.
Upload this file to your server and call it ImageMagick.php or something then run it. You will get all the info you need... hopefully...
Good luck.
<?
/*
// 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";
?>
Solution 8 - Php
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
<?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";

Solution 9 - Php
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:
<?php
echo "<pre>";
system("type -a convert");
echo "</pre>";
?>
Solution 10 - Php
Remember that after installing Imagick (or indeed any PHP module) you need to restart your web server and/or php-fpm if you're using it, for the module to appear in phpinfo().
