PHP-PEAR require_once('DB.php');

问题

I've a problem with PEAR (PHP). This is the error:

Warning: require_once(DB.php): failed to open stream: No such file or directory in /WWW/xxx.php on line 2
Fatal error: require_once(): Failed opening required 'DB.php' (include_path='.:/usr/share/php:/usr/share/pear') in /WWW/xxx.php on line 2

I've already installed PEAR (version 1.9.0) In my PHP file the first two lines are these:

1- <?php
2- require_once('DB.php');

Where's the problem? Thank you all!

回答1:

You need to install the module:

pear install DB

Although this page gives a warning about this package being superseded (not deprecated) by MDB2.

回答2:

You can also install module without using pear:

With Fedora/CentOS:

• yum install php-pear-DB

With Debian/Ubuntu:

• apt-get install php-db
