PHP Packages Installing PEAR Packages

PHP Packages



Installing PEAR Packages

Problem

You want to install a PEAR package.

Solution

Download and install the package from the PEAR Channel server using Pryus:

       % php pyrus.phar install pear/Package_Name

You can also install from another PEAR Channel:

       % php pyrus.phar install channel/Package_Name

You can also install from any location on the Internet:

       % php pyrus.phar install http://pear.example.com/Package_Name-1.0.0.tgz

Here’s how to install if you have a local copy of a package:

       % php pyrus.phar install Package_Name-1.0.0.tgz

Discussion

To install PEAR packages, you need write permission where the packages are stored; this defaults to /usr/local/lib/php/.

You can also request multiple packages at the same time:

      % php pyrus.phar install pear/XML_RSS pear/XML_SVG
      Pyrus version 2.0.0a4 SHA-1: 72271D92C3AA1FA96DF9606CD538868544609A52
      Using PEAR installation found at /Users/rasmus/lib
      Downloading pear.php.net/XML_RSS
      Mime-type: application/octet-stream
      Downloading pear.php.net/XML_SVG=====================>] 100% ( 6/ 6 kb)
      Mime-type: application/octet-stream
      Installed pear.php.net/XML_RSS-1.0.2=====================>] 100% ( 7/ 7 kb)
      Installed pear.php.net/XML_SVG-1.1.0

When installing a package, Pyrus checks that you have all the necessary PHP functions and PEAR packages that the new package depends on. If this check fails, it installs all required PEAR dependencies:

       % php pyrus.phar install pear/XML_XUL-alpha
       Pyrus version 2.0.0a4 SHA-1: 72271D92C3AA1FA96DF9606CD538868544609A52
       Using PEAR installation found at /Users/rasmus/lib
       Downloading pear.php.net/XML_XUL
       Mime-type: application/octet-stream
       Downloading pear.php.net/XML_Util2===================>] 100% (26/26 kb)
       Mime-type: application/octet-stream
       Downloading pear.php.net/XML_Parser2==================>] 100% (16/16 kb)
       Mime-type: application/octet-stream
       Installed pear.php.net/XML_XUL-0.9.1====================>] 100% (11/11 kb)
       Installed pear.php.net/XML_Util2-0.1.0
       Installed pear.php.net/XML_Parser2-0.1.0

Once a PEAR package is installed, use it in your PHP scripts by calling require_once. For example, here’s how to include the HTTP_Request2 package:

       require_once 'HTTP/Request2.php';

Generally, if a package name contains an underscore, replace it with a slash, and add .php to the end.

Because PEAR packages are included as regular PHP files, make sure the directory containing the PEAR packages is in your include_path. If it isn’t, include_once and require_once can’t find PEAR class files.
