To install the PECL on debian based linux distros (ubuntu, mint, kali, etc.)
Use the apitude command:

sudo apt-get install php-pear

I hope helped someone

Options to pass to configure (with -D or --configureoptions=) need to be specified this way in a Dockerfile RUN command:

RUN pecl install -D 'with-example-dir="/dir" enable-example-thing="yes"' package
or
RUN pecl install --configureoptions='with-example-dir="/dir" enable-example-thing="yes"' package

Otherwise, docker build might quote the command in a way that pecl doesn't parse correctly, and the build will fail with an error like this one:

PHP Fatal error:  Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array, null given in /usr/local/lib/php/PEAR/Builder.php:397

on Mageia Linux use urpmi

[afk@mageia5][~]$ sudo urpmi php-pear

The Arch Linux package that contains PECL is 'php-pear'

# pacman -S php-pear

To compile pecl extensions on Amazon Linux AMIs, follow the tutorial at http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-LAMP.html and then install these additional required packages with the following command:

[ec2-user ~]$ sudo yum install php-devel zlib-devel curl-devel gcc

You should then be able to compile pecl extensions; for example, enter the following command to compile the pecl_http extension:

[ec2-user ~]$ sudo pecl install pecl_http

Install pecl for gentoo:

emerge dev-php/PEAR-PEAR

to use the pecl, pear, or phpize commands in fedora, install the php-devel package:
$ yum install php-devel
