Pear 安装注意事项

Verifying the include path

To use PEAR and PEAR compatible packages in your applications, you normally include them into your PHP scripts using require_once(). For this to work, PEAR'sphp_dir must be a part of PHP's include path.

1. First, check where PEAR installs .php files:

   $ pear config-get php_dir
   /usr/share/lib/php/

   This directory will contain System.php.

2. Now it's time to find which configuration file is used by your PHP installation. On command line, execute:

   $ php --ini
   Configuration File (php.ini) Path: /etc/php/cli-php5
   Loaded Configuration File:         /etc/php/cli-php5/php.ini
   Scan for additional .ini files in: /etc/php/cli-php5/ext-active
   Additional .ini files parsed:      /etc/php/cli-php5/ext-active/php_gtk2.ini,
   /etc/php/cli-php5/ext-active/xdebug.ini

   To see which php.ini is used by PHP on your web server, create a file with only <?php phpinfo(); ?> as the contents, and save it in your local web root ascheck_php.php. Open the file in your browser as http://localhost/check_php.php, to find the path to the php.ini file your web server is using.

3. Now check PHP's include_path setting on command line:

   $ php -c /path/to/php.ini -r 'echo get_include_path()."\n";'

   To check PHP's include_path in your web server, create a file with only <?php phpinfo(); ?> as the contents, and save it in your local web root as check_php.php. Open the file in your browser as http://localhost/check_php.php, to verify the include_path your web server is using.

   In every case, PEAR's php_dir should be in the include path. If not, add it in your system's php.ini.

   
   

   这里特别要注意，如果你用的wamp，实际在起作用的php.ini并不是在php文件夹下，而是在apache里
