imagemagick version mismatch

[Shivam Mathur]

For PHP 7.4 and lower after the release of imagick 3.6.0RC1, ImageMagick was updated, so it gives the version mismatch warning

PHP Warning:  Version warning: Imagick was compiled against ImageMagick version 1799 but version 1808 is loaded. Imagick will run but may behave surprisingly in Unknown on line 0

While this is a warning, it breaks PhpManager installing any extensions specified after imagick.
Test workflow: https://github.com/shivammathur/test-setup-php/actions/runs/1447619348/workflow

This can be fixed temporarily by changing the $pageUrl in Install-ImagickPrerequisite.ps1 to archives, but when imagick 3.6.0 releases it would break again as the change will have to be reverted, as that will use newer ImageMagick.

Also, I noticed now the ImageMagick DLLs are inside the extension zip for versions lower than PHP 8.0, so maybe using those instead of downloading the library might help.

I checked the ImageMagick versions used to build the different imagick versions:

Imagick \ PHP	5.3	5.4	5.5	5.6	7.0	7.1	7.2	7.3	7.4	8.0
3.1.2	6.8.8-4 Q16	6.8.8-4 Q16	6.8.8-4 Q16	6.8.8-4 Q16	x	x	x	x	x	x

So, in order to install the correct ImageMagick version, we need to know the version of PHP and the version of imagick.

At the moment, Install-PhpExtensionPrerequisite (and Install-ImagickPrerequisite) is only aware of the PHP version, so this is a problem.

We have 2 options:

1. get rid of the Install-ImagickPrerequisite function
   I noticed that the php_imagick-....zip files available at https://windows.php.net/downloads/pecl now come with the required ImageMagick DLLs (IIRC it was not so a few years ago), so we don't have to download another file with the ImageMagick dependencies
2. add a new (required) argument to Install-PhpExtensionPrerequisite and Install-ImagickPrerequisite with the imagick version
   In order to know it we'd need to call Get-PhpExtension:

   $extensionVersion = (Get-PhpExtension -Path Path\To\php_imagick.dll).Version

There will be a change required in setup-php in both cases, so option 1 seems better, but whatever is easier for you.

[Michele Locati]

so option 1 seems better

Here it is: #95.

I'm going to publish a new release with this fix as soon as your code is ready.

[Michele Locati]

@shivammathur just drop me a note when you are ready

[Shivam Mathur]

@mlocati Please go ahead with the release.

[Michele Locati]

@shivammathur Done

[Shivam Mathur]

Awesome! Thanks for fixing this quickly.
