Installing the ZF2 Composition Packs (Zend Framework 2)

when you use the zend skeleton to launch a new project and the composer to install packages, he recommends this:

"doctrine/common": "Doctrine\\Common >=2.1 for annotation features", "ext-intl": "ext/intl for i18n features", "pecl-weakref": "Implementation of weak references for Zend\\Stdlib\\CallbackHandler", "zendframework/zendpdf": "ZendPdf for creating PDF representations of barcodes", "zendframework/zendservice-recaptcha": "ZendService\\ReCaptcha for rendering ReCaptchas in Zend\\Captcha and/or Zend\\Form"

I could install zendpdf, zendservice-recaptcha and doctine / common package, but not PECL.

It seems a little sad to me that zf2 offers packages, but leaves users alone how to properly configure the .json composer.

I heard that the composer can also receive PECL packages, but could not find any documentation on it.

How to install them?

To install the suggested packages, modify composer.json to include them.

 "repositories": [ { "type": "composer", "url": "http://packages.zendframework.com/" } ], "require": { "php": ">=5.3.3", "zendframework/zendframework": "2.*", "doctrine/common": "dev-master", "zendframework/zendpdf": "2.*", "zendframework/zendservice-recaptcha": "2.*" }

Then run

 php composer.phar update

Note: this composer installs doctrine / common with

 git clone http://github.com/doctrine/common

On Windows git, the PATH environment variable must be specified.

As for ext / intl, this extension is associated with PHP with PHP version 5.3.0. and can be found in the ext / folder of your php installation. [one]

To enable, uncomment (delete the half-column before the directive) in php.ini

 extension=php_intl.dll

As for pecl-weakref, it is also a PHP extension, but it is not php related and should be installed. More information on how to do this can be found at http://php.net/manual/en/install.pecl.php

The DLL for this PECL extension is currently unavailable. See Also based on the Windows section. [4]
