PHP and PEAR version dependencies

Hi all,
I would like to know if on a system with

PEAR Version: 1.3.2
PHP Version: 4.3.10

it is possible to update the version of pear without updating the
version of php in order to install recent versions of pear modules
without changing the php.
Moreover, does this make sense? I think that probably many pear
modules can be used with php4, also if cannot be installed with old
version of pear (am I wrong?) For a given pear module is anyware
documented the supported php version?

Thanks in advance

Valeria

I guess it would depend on exactly which package(s) you want to update.

You'll probably get your best information in pear.php.net, where the
developers hang out.

Definitely. PEAR itself still runs fine on PHP 4, although you should
probably consider upgrading to 4.4.7 for non-PEAR reasons to do with
security.

Note that 1.3.2 is a _really_ old version of PEAR, though, and upgrading
will be slightly more difficult than just running "pear upgrade PEAR".
The instructions are at http://pear.php.net/news/package.xml.1.0.php, but
it basically boils down to running four pretty simple upgrade commands at
the command line.

You can see which version of PHP a given PEAR package requires by going
to the "Download" tab of the package home page. For example, the relevant
page for the MDB2 package is at http://pear.php.net/package/MDB2/
download, and indicates that it has a dependency on PHP 4.3.2 or later.

Note that you will need to upgrade PEAR to at least version 1.4 (and
preferably the current version 1.6.1) before you can install a lot of
recent package versions, as the package metadata format changed from PEAR
1.3 to 1.4.
