The default PHP version of apt-get In Ubuntu 10.10 is 5.3. Currently, ZendOptimizer supports up to 5.2 php versions.
Therefore, to support ZendOptimizer, you must downgrade the PHP version to version 5.2, and the apt package management tool supports downgrading the version of a specific package.

For example, we found that Karmic Koala is the default PHP version of Ubuntu 9.10 is 5.2, so we can downgrade the 5 software packages we need php5-cli libapache2-mod-php5 php5-gd php5-mysql php5-common to 5.2 in the following way.

First, delete all currently installed php related suites.
$ Sudo apt-get purge 'dpkg-l | grep php | awk '{print $2 }'

Switch to root identity
$ Sudo-I

PHP downgrade is supported for creating dependency files
# Echo-e "Package: php5/nPin: release a = karmic/nPin-Priority: 991/n">/etc/apt/preferences. d/php
# Apt-cache search php5-| grep php5-| awk '{print "Package:", $1, "/nPin: release a = karmic/nPin-Priority: 991/n "} '>/etc/apt/preferences. d/php
# Apt-cache search-n libapache2-mod-php5 | awk '{print "Package:", $1, "/nPin: release a = karmic/nPin-Priority: 991/n "} '>/etc/apt/preferences. d/php
# Apt-cache search-n php5-mysql | awk '{print "Package:", $1, "/nPin: release a = karmic/nPin-Priority: 991/n "} '>/etc/apt/preferences. d/php
# Apt-cache search-n php5-gd | awk '{print "Package:", $1, "/nPin: release a = karmic/nPin-Priority: 991/n "} '>/etc/apt/preferences. d/php

Exit root identity
# Exit

Create APT Source for Karmic (Ubuntu 9.10)
$ Sudo vim/etc/apt/sources. list. d/karmic. list
Deb http://old-releases.ubuntu.com/ubuntu karmic main restricted universe multiverse
Deb-src http://old-releases.ubuntu.com/ubuntu karmic main restricted universe multiverse
Deb http://old-releases.ubuntu.com/ubuntu karmic-updates main restricted universe multiverse
Deb-src http://old-releases.ubuntu.com/ubuntu karmic-updates main restricted universe multiverse
Deb http://old-releases.ubuntu.com/ubuntu karmic-security main restricted universe multiverse
The deb-src http://old-releases.ubuntu.com/ubuntu karmic-security main restricted universe multiverse

Update APT data
$ Sudo apt-get update

Install php5-cli libapache2-mod-php5 php5-gd php5-mysql php5-common these 5 software packages
$ Sudo apt-get install-t karmic php5-cli libapache2-mod-php5 php5-gd php5-mysql php5-common

Check the PHP version. We can see that the version has been successfully downgraded to 5.2.
