Downgrade php3 – php2, gỡ lỗi

PHP3 có hiện đại thật nhưng cũng hại điện không kém. Vì thế một số ứng dụng chỉ nên chạy với php2 (ví dụ như ứng dụng viết trên Zend Framework chẳng hạn).

Vì vậy bạn cần phải downgrade từ phiên bản 3 xuống phiên bản 2 khi đã lỡ cài đặt nó. Với windows thì việc này không vấn đề gì. Mình thường đặt sẵn mấy phiên bản PHP cạnh nhau, muốn đổi chỉ cần config lại apache là xong.

Tuy nhiên nó lại khá phiền toái với nhứng OS tự động cài đặt. Như Ubuntu mà mình đang sử dụng đây.

Vì thế sau khi search google, tìm được 2 đoạn shell script xài được. Note vào đây cho dễ nhớ này:

# OK, here’s how to do the Apt magic to get PHP packages from the karmic repositories:

echo “Am I root? “
if [ "$(whoami &2>/dev/null)" != "root" ] && [ "$(id -un &2>/dev/null)" != "root" ] ; then
echo “ NO!

Error: You must be root to run this script.
Enter
sudo su
“
exit 1
fi
echo “ OK”;

#install aptitude before, if you don`t have it:
apt-get install aptitude
# or if you prefer apt-get use:
# alias aptitude=’apt-get’

# finish all apt-problems:
aptitude update
aptitude -f install
#apt-get -f install

# remove all your existing PHP packages. You can list them with dpkg -l| grep php
PHPLIST=$(for i in $(dpkg -l | grep php|awk ‘{ print $2 }’ ); do echo $i; done)
echo these pachets will be removed: $PHPLIST
# you need not to purge, if you have upgraded from karmic:
aptitude remove $PHPLIST
# on a fresh install, you need purge:
# aptitude remove –purge $PHPLIST

#Create a file each in /etc/apt/preferences.d like this (call it for example /etc/apt/preferences.d/php5_2);
#
#Package: php5
#Pin: release a=karmic
#Pin-Priority: 991
#
#The big problem is that wildcards don’t work, so you will need one such stanza for each PHP package you want to pull from karmic:

echo ”>/etc/apt/preferences.d/php5_2
for i in $PHPLIST ; do echo “Package: $i
Pin: release a=karmic
Pin-Priority: 991
“>>/etc/apt/preferences.d/php5_2; done

# duplicate your existing sources.list replacing lucid with karmic and save it in sources.list.d:
#sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list

# better exactly only the needed sources, cause otherwise you can get a cachsize problem:
echo “# needed sources vor php5.2:
