     * Enable the extension(s) in php.ini you want to use by uncommenting
       the extension=php_*.dll lines in php.ini. This is done by deleting
       the leading ; from the extension you want to load.

   Example 2-8. Enable Bzip2 extension for PHP-Windows
// change the following line from ...
;extension=php_bz2.dll

// ... to
extension=php_bz2.dll

     * Some of the extensions need extra DLLs to work. Couple of them can
       be found in the distribution package, in the C:\php\dlls\ folder
       in PHP 4 or in the main folder in PHP 5, but some, for example
       Oracle (php_oci8.dll) require DLLs which are not bundled with the
       distribution package. If you are installing PHP 4, copy the
       bundled DLLs from C:\php\dlls folder to the main C:\php folder.
       Don't forget to include C:\php in the system PATH (this process is
       explained in a separate FAQ entry).
     * Some of these DLLs are not bundled with the PHP distribution. See
       each extensions documentation page for details. Also, read the
       manual section titled Installation of PECL extensions for details
       on PECL. An increasingly large number of PHP extensions are found
       in PECL, and these extensions require a separate download.

     Note: If you are running a server module version of PHP remember to
     restart your webserver to reflect your changes to php.ini.

   required additional dlls.

Chapter 3. Installation of PECL extensions

Introduction to PECL Installations

   PECL is a repository of PHP extensions that are made available to you
   via the PEAR packaging system. This section of the manual is intended
   to demonstrate how to obtain and install PECL extensions.

   These instructions assume /your/phpsrcdir/ is the path to the PHP
   source distribution, and that extname is the name of the PECL
   extension. Adjust accordingly. These instructions also assume a
   familiarity with the pear command.

   To be useful, a shared extension must be built, installed, and loaded.
   The methods described below provide you with various instructions on
   how to build and install the extensions, but they do not automatically
   load them. Extensions can be loaded by adding an extension directive.
   To this php.ini file, or through the use of the dl() function.

   When building PHP modules, it's important to have known-good versions
   of the required tools (autoconf, automake, libtool, etc.) See the
   Anonymous CVS Instructions for details on the required tools, and
   required versions.
     _________________________________________________________________

Downloading PECL extensions

   There are several options for downloading PECL extensions, such as:

     * http://pecl.php.net
       The PECL web site contains information about the different
       extensions that are offered by the PHP Development Team. The
       information available here includes: ChangeLog, release notes,
       requirements and other similar details.
     * pear download extname
       PECL extensions that have releases listed on the PECL web site are
       available for download and installation using the pear command.
       Specific revisions may also be specified.
     * CVS
       Most PECL extensions also reside in CVS. A web-based view may be
       seen at http://cvs.php.net/pecl/. To download straight from CVS,
       the following sequence of commands may be used. Note that phpfi is
       the password for user cvsread:

$ cvs -d:pserver:[e-mail]:/repository login
$ cvs -d:pserver:[e-mail]:/repository co pecl/extname

     * Windows downloads
       Windows users may find compiled PECL binaries by downloading the
       Collection of PECL modules from the PHP Downloads page, and by
       retrieving a PECL Snapshot. To compile PHP under Windows, read the
       Win32 Build README.
     _________________________________________________________________

PECL for Windows users

   As with any other PHP extension DLL, installation is as simple as
   copying the PECL extension DLLs into the extension_dir folder and
   loading them from php.ini. For example, add the following line to your
   php.ini:

   extension=php_extname.dll

   After doing this, restart the web server.
     _________________________________________________________________

Compiling shared PECL extensions with PEAR

   PEAR makes it easy to create shared PHP extensions. Using the pear
   command, do the following:

   $ pear install extname

   This will download the source for extname, compile, and install
   extname.so into your extension_dir. extname.so may then be loaded via
   php.ini

   By default, the pear command will not install packages that are marked
   with the alpha or beta state. If no stable packages are available, you
   may install a beta package using the following command:

   $ pear install extname-beta

   You may also install a specific version using this variant:

   $ pear install extname-0.1
     _________________________________________________________________

Compiling shared PECL extensions with phpize

   Sometimes, using the pear installer is not an option. This could be
   because you're behind a firewall, or it could be because the extension
   you want to install is not available as a PEAR compatible package,
   such as unreleased extensions from CVS. If you need to build such an
   extension, you can use the lower-level build tools to perform the
   build manually.

   The phpize command is used to prepare the build environment for a PHP
   extension. In the following sample, the sources for an extension are
   in a directory named extname:

$ cd extname
$ phpize
$ ./configure
$ make
# make install

   A successful install will have created extname.so and put it into the
   PHP extensions directory. You'll need to and adjust php.ini and add an
   extension=extname.so line before you can use the extension.
     _________________________________________________________________

Compiling PECL extensions statically into PHP

   You might find that you need to build a PECL extension statically into
   your PHP binary. To do this, you'll need to place the extension source
   under the php-src/ext/ directory and tell the PHP build system to
   regenerate its configure script.

$ cd /your/phpsrcdir/ext
$ pear download extname
$ gzip -d < extname.tgz | tar -xvf -
$ mv extname-x.x.x extname

   This will result in the following directory:

   /your/phpsrcdir/ext/extname

   From here, force PHP to rebuild the configure script, and then build
   PHP as normal:

$ cd /your/phpsrcdir
$ rm configure
$ ./buildconf --force
$ ./configure --help
$ ./configure --with-extname --enable-someotherext --with-foobar
$ make
$ make install

     Note: To run the 'buildconf' script you need autoconf 2.13 and
     automake 1.4+ (newer versions of autoconf may work, but are not
     supported).

   Whether --enable-extname or --with-extname is used depends on the
   extension. Typically an extension that does not require external
   libraries uses --enable. To be sure, run the following after
   buildconf:

   $ ./configure --help | grep extname

Chapter 4. Problems?

Read the FAQ

   Some problems are more common than others. The most common ones are
   listed in the PHP FAQ, part of this manual.
     _________________________________________________________________

Other problems

   If you are still stuck, someone on the PHP installation mailing list
   may be able to help you. You should check out the archive first, in
   case someone already answered someone else who had the same problem as
   you. The archives are available from the support page on
   http://www.php.net/support.php. To subscribe to the PHP installation
   mailing list, send an empty mail to
   [e-mail]. The mailing list address is
   [e-mail].

   If you want to get help on the mailing list, please try to be precise
   and give the necessary details about your environment (which operating
   system, what PHP version, what web server, if you are running PHP as
   CGI or a server module, safe mode, etc...), and preferably enough code
   to make others able to reproduce and test your problem.
     _________________________________________________________________

Bug reports

   If you think you have found a bug in PHP, please report it. The PHP
   developers probably don't know about it, and unless you report it,
   chances are it won't be fixed. You can report bugs using the
   bug-tracking system at http://bugs.php.net/. Please do not send bug
   reports in mailing list or personal letters. The bug system is also
   suitable to submit feature requests.

   Read the How to report a bug document before submitting any bug
   reports!
