I recently had to install PEAR into a PHP environment on a Linux machine, and as I did the install I wrote it up. This information is pretty easy to find, but I like to write these things up so I don’t forget them in future and have to keep going round in circles trying to find information. I thought it might be useful for others, so here it is.
Installing PEAR into a PHP/Apache install
Download the go-pear.php script from http://go-pear.org/.
Open a command line shell and run the script:
Welcome to go-pear!
Go-pear will install the 'pear' command and all the files needed by
it. This command is your tool for PEAR installation and maintenance.
Go-pear also lets you download and install the PEAR packages bundled
with PHP: MDB2.
If you wish to abort, press Control-C now, or press Enter to continue:
HTTP proxy (http://user:email@example.com:port), or Enter for none:: http://my-proxy-server.com:80
Below is a suggested file layout for your new PEAR installation. To
change individual locations, type the number in front of the
directory. Type 'all' to change all of them or simply press Enter to
accept these locations.
1. Installation prefix : /usr
2. Binaries directory : $prefix/bin
3. PHP code directory ($php_dir) : $prefix/share/pear
4. Documentation base directory : $php_dir/docs
5. Data base directory : $php_dir/data
6. Tests base directory : $php_dir/tests
7. Temporary files directory : $prefix/temp
1-7, 'all' or Enter to continue:
The following PEAR packages are bundled with PHP: MDB2.
