PHP: Class 'Phar' not found

Question

I try to use the Silex framework as base for my web application. However, if I try to include the *.phar archive, PHP throws the following error:

Fatal error: Class 'Phar' not found in /var/www/framework/silex.phar on line 11

The following relevant lines are in my /etc/php/php.ini (as suggested in the docs of Silex):

extension=phar.so
phar.readonly = Off
phar.require_hash = Off
detect_unicode = Off

The PHAR library is present in /usr/lib/php/modules/phar.so which is set as the extension path for all libraries in my php.ini

Does anyone know why PHP is throwing this error?

Answer 1

Try specifying the path to the extension:

php -d extension=phar.so composer.phar <your_script>

Other options:

Based on the information you provided, there are a few possibilities:

• You are using a different php.ini. Check the output of phpinfo() to confirm, and ensure that you are editing the active one.

• /usr/lib/php/modules/phar.so is not readable. Ensure that the web server user can read this file.

• Your web server has not been restarted since you last added the phar-related information to php.ini. Restart your webserver.

Answer 2

This works for me:

php -d extension=phar.so composer.phar [... your command ...]

This includes the phar extension for the current runtime. Works for shared / VPC servers.

Answer 3

On CentOS ...

• phar.so is contained in the php-common package.
• the phar executable is contained in the php-cli package.
• php-mbstring and php-bz2 also seems to be required.

When php -m | grep phar returns nothing, one has to add these .ini files for the CLI:

sudo cp /etc/php-zts.d/phar.ini /etc/php-cli.d/phar.ini
sudo cp /etc/php-zts.d/mbstring.ini /etc/php-cli.d/mbstring.ini
sudo cp /etc/php-zts.d/bz2.ini /etc/php-cli.d/bz2.ini

Alternatively, one can add the same module .ini files as the webserver uses:

sudo cp /etc/php-zts.d/* /etc/php-cli.d/

It should look alike this:

$ php --ini

Configuration File (php.ini) Path: /etc
Loaded Configuration File:         /etc/php.ini
Scan for additional .ini files in: /etc/php-cli.d/
Additional .ini files parsed:      /etc/php-cli.d/bz2.ini,
/etc/php-cli.d/mbstring.ini,
/etc/php-cli.d/phar.ini

Then one can run it:

$ php ./composer.phar
   ______
  / ____/___  ____ ___  ____  ____  ________  _____
 / /   / __ \/ __ `__ \/ __ \/ __ \/ ___/ _ \/ ___/
/ /___/ /_/ / / / / / / /_/ / /_/ (__  )  __/ /
\____/\____/_/ /_/ /_/ .___/\____/____/\___/_/
                    /_/

And move it below the $PATH:

sudo mv ./composer.phar /usr/local/bin/composer
