2.1 Install PHP Recommended Extensions

Install REMI Repository

Command to enabled the CRB repository:

subscription-manager repos --enable codeready-builder-for-rhel-9-x86_64-rpms

Command to install the EPEL repository configuration package:

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

Command to install the Remi repository configuration package:

dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm

Install ImageMagick (Image Manipulation) Tool

To use the ImageMagick tool with PHP or Perl programming language, you will need to install ImageMagick with the Imagick PHP extension for PHP and ImageMagick-Perl extension for Perl.

Imagick is a simple PHP extension for creating and modifying images using the ImageMagick API program. There is a confusion in name, as people think that ImageMagick and Imagick both are the same, but you can use ImageMagick without Imagick extension but you need both installed on your machine to use and run it.

Installing ImageMagick from Repository

First, install following prerequisite php-pear, php-devel and gcc packages to compile the Imagick PHP extension.

sudo dnf install php-pear php-devel gcc

Once you’ve installed php-pear, php-devel, and gcc packages, you may now install ImageMagick software for PHP and Perl support using dnf command.

sudo dnf install ImageMagick ImageMagick-devel ImageMagick-perl

Next, verify that ImageMagick has been installed on your system by checking its version.

convert --version

Installing ImageMagick 7 from Source Code

To install ImageMagick from source, you need a proper development environment with a compiler and related development tools. If you don’t have the required packages on your system, install development tools as shown:

sudo dnf groupinstall 'Development Tools'
sudo dnf -y install bzip2-devel freetype-devel libjpeg-devel libpng-devel libtiff-devel giflib-devel zlib-devel ghostscript-devel djvulibre-devel libwmf-devel jasper-devel libtool-ltdl-devel libX11-devel libXext-devel libXt-devel lcms-devel libxml2-devel librsvg2-devel OpenEXR-devel php-devel

Now, download the latest version of the ImageMagick source code using the following wget command and extract it.

wget https://www.imagemagick.org/download/ImageMagick.tar.gz
tar xvzf ImageMagick.tar.gz

Configure and compile the ImageMagick source code. Depending on your server hardware specs, this may take some time to finish.

cd ImageMagick*
./configure
make
make install

Verify that the ImageMagick compile and install were successful.

magick -version

Install Imagick PHP Extension

Install from PECL

Next, compile the Imagick for PHP extension. To do, simply run the following ‘pecl‘ command. It will install ImageMagick and imagick PHP extension module imagick.so under /usr/lib/php/modules directory. If you are using a 64-bit system, the module directory path would be /usr/lib64/php/modules.

Note: It will ask you to provide Imagemagick installation prefix, simply hit enter to auto-detect.

sudo pecl install imagick

Install from REMI Repository

If for some reason the installation from pecl fails, we can install the extension from the REMI repository:

sudo dnf install php84-php-pecl-imagick-im7

Now, add the imagick.so extension to /etc/php.ini file.

echo extension=imagick.so >> /etc/php.ini

Next, restart Apache webserver.

sudo systemctl restart httpd

Verify the Imagick PHP extension by running the following command. You will see the Imagick extension similar to below.

php -m | grep imagick

Install PHP Zip Extension

Install from package manager

Use DNF to install the PHP Zip extension:

sudo dnf install php84-php-pecl-zip libzip-devel

Add the extension to your PHP configuration file

echo "extension=zip.so" | sudo tee -a /etc/php.ini

Check the Installation

After installation, check if the Zip extension is active:

Run in the terminal:

php -m | grep zip

If you see zip in the output, the extension is active. You can also create a PHP file with this content:

<?php
if (extension_loaded('zip')) {
    echo "ZIP extension is installed.";
} else {
    echo "ZIP extension is not installed.";
}
?>

Save this as check_zip.php and run it in your browser or command line to confirm the installation.

Install using PECL (PHP Extension Community Library)

PECL offers another way to install PHP extensions. To use PECL for installing the ZIP extension:

Install PECL

sudo dnf install php-pear libzip-devel

Install the ZIP extension through PECL

sudo pecl install zip

Add the extension to your PHP configuration

echo "extension=zip.so" | sudo tee -a /etc/php.ini

Restart your web server to apply the changes.

Install Intl PHP Extension

As you have php-commom from remi repositories, you need to get php-intl from remi also.

sudo dnf install php84-php-intl

Add the extension to PHP configuration file

echo "extension=intl.so" | sudo tee -a /etc/php.ini

Add PHP extensions to path

If you installed the extensions from the REMI repository and the system still does not recognize them, you must create a symbolic link to the php path. This happens because the REMI packages are installed in a different location by default than the one where php is installed. You must do this with all the extensions, and it is done in the following way:

sudo ln -s /opt/remi/php84/root/usr/lib64/php/modules/xxx.so /usr/lib64/php/modules/xxx.so

For example:

sudo ln -s /opt/remi/php84/root/usr/lib64/php/modules/intl.so /usr/lib64/php/modules/intl.so

This will create a symbolic link, so every time the package is updated, php will recognize the updated library without needing to do anything
