[PHP] Oracle persistent connection limit
Is there a way to limit the total number of persistent connection to an oracle database? I know this functionality exists for MySQL through a setting in the php.ini but I haven't found it for oracle. I am in an environment where we have about 10 users that connect to oracle from each of 10 webservers that each have about 20 apache processes and I would like to use persistent connections but the resulting 2000 connections would overwhelm oracle. I am looking at reducing the number of users but that will be a large undertaking to go through the entire codebase. Any ideas?

Re: [PHP] Oracle persistent connection limit
That is what I figured. The problem is that oracle doesn't even seem to have per-process limits. Eric On Tue, 23 Jul 2002, Thies C.

[PHP] Re: mysql_db_query and the future?
You can add the database to your query. Such as: SELECT * FROM database.table WHERE stuff=other_stuff; I am not sure what other databases support this notation but I know that MySQL does.

[PHP] Re: some kind of "library loader"
I have had a similar idea. I also tried the custom error handler
aproach and it didn't work here either. I have set the project aside
that I was thinking about it for but I do have some ideas that would
help and may be able to contribute. I wasn't even able to get php to
call my custom error handler for function not found errors. How did you
do that? Was there anything useful in the context argument? My guess
is that to get this aproach to work would require hacking the code to
php itself but the hack wouldn't be very major. However I do have an
alternate plan that has been waiting for me to get around to building it
is a simple parser that will read a php file and get the required
functions and classes and then pre build a library file for just that
page. The parsing shouldn't be that dificult as all function calls
begin with 'func(' and for classes checking for 'new classname' or
'classname::' would give me a list of all items that need to be checked
for. Then simply build (from the source) a list of all builtin php
functions and allow those and check for declarations of inline functions
and classes while parsing and remove those. That would leave a list of
functions and classes that are external. Then build a database of
classes and functions either as a real database or simple an index of
the files that contain each resource. I don't think it would be too
hard. The next step would be to make a publicly available archive of
functions and classes that fit into this index. Or to build it into
pear.
Please keep in touch with me on this issue. Feel free to email me off
list if you want.

[PHP] Re: alphabetizing titles when first word begins with 'The','A',etc.
It could be done with MySQL itself by either adding a sort_title field that you make those changes to, by selecting the data into a temporary table then performing the appropriate updates before selecting it ordered properly, or by some crazy complex combinations of the if, index, and substr functions (all multiple times in one query). The last idea is probably the worst and an crazy hack but even that could work. In reality I would think for a reasonably small result set you would be better off simply doing the sorting in PHP where you can define your own sort functions (usort and friends) that will do whatever you want.

[PHP] Error compiling pdflib extension
I recently tried to recompile PHP-4.0.6 and my pdflib extension stopped working. I was building it in directly but the module wasn't being listed on phpinfo() and of course the pdf functions didn't work. So after many attempts I decided to try another approach and build it as a shared module. I had a very hard time finding any documentation about how to even compile a shared module at all but I did finally find it. I got it compiled but it still doesn't work. I recieve the following error message when I try to load it. Warning: Invalid library (maybe not a PHP library) 'libpdf_php.so' in /home/httpd/html/u7/lib/pdflib.inc on line 3 I tried running 'file' on the module to see if I could find any justification for that error. I recieved $ file libpdf_php.so libpdf_php.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped I am running on Mandrake 8.1 (I tried with 8.0 as well) I know that the module interface is working because I compiled many other modules (same compile) and they all work. Then I had a really strange idea, I went out and found an rpm for php-pdf-4.0.6 and extracted the share module. It worked! So now I am really confused. I am up and running but at some point I will want to upgrade so I will need find the problem. Anyone have an idea?
