How do I install / enable the PHP phar extension?

Question

I am trying to install Composer on my KnownHost VPS. When I run this command:

curl -sS https://getcomposer.org/installer | php

I get this error message:

Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:

The phar extension is missing.
Install it or recompile php without --disable-phar

How do I install the phar extension? I am running PHP 5.4.22 on my VPS.

Try this instead: `curl -sS https://getcomposer.org/installer | php -d detect_unicode=Off`. — Amal Murali, Feb 26 '14 at 16:35
@AmalMurali Yes, but the flavour of *nix makes a big difference as to what the best way of installing/enabling the phar extension is. — Paul, Feb 26 '14 at 16:37
Did you ever resolve this? I am in similar boat at DreamHost. — jerrygarciuh, Apr 09 '14 at 18:47

You can modify your php.ini file to get this working. (Some hosts use a phprc file to enable different settings in PHP instead of php.ini. @jerrygarciuh On dreamhost, follow the directions here)

After you have added your php.ini/phprc file, add these lines to the file (just the first line if your server doesn't use Suhosin for security):

extension = phar.so 
suhosin.executor.include.whitelist = phar

restart php if you need to (insert php version number with no decimals if different):

killall -9 php70.cgi

then check to make sure it is working:

php -m | grep Phar

Finish with the install of composer and you should be good to go.

If I execute `apt-get install php-phar` in suse linux then it just loads forever. – Black Jul 10 '18 at 11:53
@Black On suse linux you may prefer zypper command to install, don't you ? https://stackoverflow.com/questions/7158838/how-to-install-packages-from-command-line-on-suse – 7Tonin Jul 16 '18 at 07:02
I don't see any difference. – Black Jul 16 '18 at 07:33
For Suse, `zypper install php-phar` works fine for me – Elikill58 May 11 '23 at 13:39

In the end I solved this by getting my host to rebuild PHP with PDO support.

I got the same issue in Ubuntu 16.04. After wasting two hours, I came up with this solution:

First install your required PHP version: sudo apt install php7.2
Install the composer. curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
Check whether the composer is working by simply typing composer

If the composer is working properly, you are good to go.
