Answer 1

For servers with PHP 5.6

sudo apt-get install zip unzip php5.6-zip

Answer 2

On docker with image php:7.2-apache I just needed zip and unzip. No need for php-zip :

apt-get install zip unzip

or Dockerfile

RUN ["apt-get", "update"]
RUN ["apt-get", "install", "-y", "zip"]
RUN ["apt-get", "install", "-y", "unzip"]

Answer 3

Not to belabor the point, but if you are working in a Dockerfile, you would solve this particular issue with Composer by installing the unzip utility. Below is an example using the official PHP image to install unzip and the zip PHP extension for good measure.

FROM php:7.4-apache

# Install Composer
COPY --from=composer /usr/bin/composer /usr/bin/composer

# Install unzip utility and libs needed by zip PHP extension 
RUN apt-get update && apt-get install -y \
    zlib1g-dev \
    libzip-dev \
    unzip
RUN docker-php-ext-install zip

This is a helpful GitHub issue where the above is lovingly lifted from.

Answer 4

I'm Using Ubuntu and with the following command worked

apt-get install --yes zip unzip

Answer 5

For Debian Jessie (which is the current default for the PHP image on Docker Hub):

apt-get install --yes zip unzip php-pclzip

You can omit the --yes, but it's useful when you're RUN-ing it in a Dockerfile.

Answer 6

The shortest command to fix it on Debian and Ubuntu (dependencies will be installed automatically):

sudo apt install php-zip
