Jim,

Thanks for the script; it didn’t solve my problem, but it pushed me in the right direction.

I documented my steps here, for those who are interested: http://nerdstock.org/php_extensions

Cheers,
Rob

I found that sybase_ct.so needs to be loaded last or else you will also have unknown core dumps. Scripts execute fine but it cores just like everything else mentioned.

Thanks!

again i have now a problem with 5.2.10 version for cli.
i have seen that mssql extension must come after dba extension, otherwise i get “Segmentation fault: 11 (core dumped)” after the script is executed.

Thanks a zillion.
The re-ordering is my problem as well!

I am still trying to solve this problem on one of my servers.

I have tried using the extension reordering script and httpd still core dumps. The work around that I found, although quite unsatisfactory operationally, nevertheless works and it would be useful to find out why.

I found that if I restart the running httpd using apachectl graceful httpd coredumps. However if I comment out the LoadModule php5_module and the AddModule mod_php5.c lines, httpd starts and I can then copy back the uncommented version of httpd.conf and do a graceful restart successfully.

Another graceful restart then crashes httpd.

I am running apache 1.3.41 and php5.2.9 on freebsd 7.0

Any ideas?

If you just recently updated PHP on FreeBSD with the ports system, be sure to read /usr/ports/UPDATING, specifically the 20081211 entry. It is possible you have some extensions that are out of date with respect to the version of PHP you are running.

I saw some errors until I followed the instructions in that entry, forcing an update of pcre (I actually had to rm /usr/local/lib/php/20060613/pcre.so before reinstalling).

There are, unfortuantely, more ways to crash PHP than by extension ordering alone… :)

my original extensions.ini:
extension=pgsql.so
extension=pdf.so
extension=ctype.so
extension=simplexml.so
extension=spl.so
extension=dom.so
extension=filter.so
extension=hash.so
extension=iconv.so
extension=json.so
extension=pdo.so
extension=pdo_sqlite.so
extension=posix.so
extension=session.so
extension=sqlite.so
extension=tokenizer.so
extension=xml.so
extension=xmlreader.so
extension=xmlwriter.so
extension=zip.so
extension=zlib.so

after running fixphpextorder.sh:
extension=pgsql.so
extension=pdf.so
extension=ctype.so
extension=simplexml.so
extension=dom.so
extension=filter.so
extension=hash.so
extension=iconv.so
extension=json.so
extension=pdo.so
extension=pdo_sqlite.so
extension=posix.so
extension=session.so
extension=tokenizer.so
extension=xmlreader.so
extension=xmlwriter.so
extension=zip.so
extension=zlib.so
extension=spl.so
extension=sqlite.so
extension=xml.so

issuing “/usr/local/etc/rc.d/apache2 graceful” gives “Performing a graceful restart”

but “/usr/local/etc/rc.d/apache2 status” says “apache2 is not running.”

httpd-error.log shows:
[notice] Graceful restart requested, doing restart
[notice] seg fault or similar nasty error detected in the parent process
[warn] pid file /var/run/httpd.pid overwritten — Unclean shutdown of previous Apache run?
[notice] Apache/2.0.63 (FreeBSD) PHP/5.2.8 with Suhosin-Patch configured — resuming normal operations

the output of the commands above is the same when i was using my original extensions.ini..

FreeBSD 7.1-STABLE

please help. TIA!

Thanks for your helpful post! Although the script didn’t eliminate the error messages, it gave me some ideas. I solved it by removing some modules.
