Most ISPs have PEAR DB installed. Ask your ISP to install it if they haven't already. You can tell if PEAR DB has been installed by trying the PHP code in Example 9-7 to see whether the require_once ('DB.php'); line causes an error when the script is executed. Adding Additional Packages Once that's complete, you can access the PEAR Package Manger by entering pear at the command prompt. Adding new modules is as easy as executing pear packagename . You won't need to do anything, since the DB package was installed along with the install by default. However, if you're running Windows XP Home, you'll need to take these steps to install the PEAR DB: C:\>cd c:\php To find out what versions of PEAR packages are installed, execute pear list. That returns a listing such as the one shown in Figure 9-6.
Once you've got PEAR installed, you're ready to try it out. |
