Php5 >> Php4

Eric45008 · 04-24-2005, 12:33 AM

I have been using PHP 4 for a while now and it worked great on my server. I upgraded to PHP5 and now 90% of my php scripts show up blank. Is there anyway to make Apache2 load the old modules? What files do I need to change? -Eric

just change the php module apache loads in httpd.conf. But if you installed from a slackpack, your previous installation has prolly been wiped out. So, easiest way is to first remove the php package, then install again the php4 package you had.

Remember tho, that with /var/log/apache2/error_log at your usage, you could allways solve the problems, instead of fleeing to a previous version.

You can also try to run the scripts from command-line, sometimes usefull for debugging. And when they show "blank pages" it's often because the script had an error before showing anything.

I think this could be something to do with register globals, you may have to rewrite your scripts using super global arrays.

Well, it's not always errors. When I installed PHPBB it rejected it saying that the PHP version was incompatible with MySQL 4.

Also, how do you uninstall a package?

reddazz · 04-24-2005, 08:41 AM

A lot of forum software and content management systems are not yet compatible with php5. Phpbb works with mysql 4, I use it myself. To uninstall, go to the directory from which you installed and do "make uninstall" as root.

See this url to check compatibily between PHP4 and 5
http://fr2.php.net/manual/en/migrati...compatible.php

To uninstall a package : removepkg <package name> or use pkgtool

If the package was installed from a slackware package (.tgz) you can just do as root:
removepkg packagename

I removed:

php4
php5
apache2

Apache refuses to start. I REALLY need to get this thing running:

Right after I removed apache2 I deleted all the apache2 directories on the server and tried to install the apache2-php4 package on linuxpackages.net:

root@ehost:~# installpkg apache2.tgz
Installing package apache2...
PACKAGE DESCRIPTION:
Executing install script for apache2...
cat: etc/apache2/httpd.conf: No such file or directory

Why not use apache version (1.3.33) that comes with slackware ?
It works well with php here

Eric45008 · 04-24-2005, 01:52 PM

I prefer Apache2...how would I get back to 1.3 anyway and install php + mysql for it? Hmm I think I'm gonna have to reinstall slackware and reinstall all the packages.

Eric45008 · 04-24-2005, 02:10 PM

I finally got the package to install correctly. I get this error when I try and start Apache:

# apachectl start
/usr/sbin/httpd: error while loading shared libraries: libaprutil-0.so.0: cannot open shared object file: No such file or directory

Please help.

Eric45008 · 04-24-2005, 04:34 PM

Removed apache2-php package again, added apache2 alone, then added php4 alone. Apache2 works great without php but with php:

Cannot load /usr/modules/libphp4.so into server: /usr/modules/libphp4.so: cannot open shared object file: No such file or directory

gbonvehi · 04-24-2005, 05:09 PM

Try to locate libphp4.so in your system and make a symlink to it in /usr/modules/ so apache can find it. I think you can also achieve this by modifing apache config files and set it to look for libphp where it's.

I did that before, when I did it said something about an undefined variable.
