Here is an introduction to the installation of pear (this is important):

First of all, the PHP include path problem, this is similar to Java classpath, there is a default path, such as PHP.ini set a few default path/etc/include or/etc/demo, then in the PHP code, If there is a similar "include ' file.php ';" The inclusion of the statement, the execution of the program will be in the current folder search whether there is a file.php this file, if not, then go to search/etc/include or/etc/demo folder whether there is this file, if still not, then error!

For the foreign virtual host, many have installed PEAR, and the installation of the PEAR package is very complete, so you in PHP file reference include "PEAR.php", The program will be referenced based on the path php.ini finds pear, but if the virtual host does not have pear installed, we will have to install it ourselves.

Install pear is a very simple process, can not fear, the following or guide you to see the Help manual, link here (because many people do not understand the pear file structure, so this manual was deleted), but no relationship, you can go to this link to see. Probably very few people have the patience to look down, anyway I can not go down, in fact, the most important thing is this line, that is to tell you the default include path to add PHP method

OK, let's start with the installation steps:

First in the root directory of the site suggested folder "Tutor", and then set up a Folder inc, download pear, the current latest version of the download address is http://download.pear.php.net/package/PEAR-1.6.1.tgz.
Download complete unzip, put Pear in the INC directory, expand the directory;
Path to the Includedefine,].define,web_dir.//pear directory
, Pear_dir. Path_separator.? >
Open http://127.0.0.1/tutor/demo.php again and find out what? The mistake is gone!
At this point, pear installation ends
