RE: [PHP-DB] Persistent Connections to Oracle databases

I know this is a late response, but I haven't seen anybody point this out yet: that's 1 connection *per Apache child process*, since each process still has to have its own connection. But in fact it is not what is happening, every time I submit the page to the same database a new connection is opened. Which is a little bit annoying if I submit this one 100 times (100 connections at the end). Potentially, if you have Apache configured to run 100 children or more. If you configure it to run only 50 children, that's the maximum number of Oracle connections you will get. Cheers!

[PHP-DB] Replacing subtring within table record
I want to replace one substring with another within a MySQL table record, eg a blob. Do I need to extract the record and do it in php or can I do it directly with mysql? The Replace Syntax notes in mysql.com seem to relate to replacing the whole row and I'm not quite confident with shell commands.

[PHP-DB] multiple returned lob resource being overwritten in oci8
Hi,
I am selecting multiple columns from a table, one being a clob. the
query returns multiple records for the query. The results are all good,
except the clob column. The last returned record's clob column
overwrites all previous clob columns (all the previous records have
there unique data, except the clob columns which contains the data for
the last record across all previous records), depending on how I fetch the
data.
A working example:
$query = 'select
id,
author,
cdate,
views,
title,
message,
top
from
APP_THREADS
where
TYPE = \'D\'';
$stmt = ociparse($fw_db-connection, $query);
ociexecute($stmt);
while (OCIFetchInto ($stmt, $row, OCI_ASSOC)) {
echo $row['MESSAGE']-load();
}
with the output being something like this:
clob1
clob2
clob3
clob4
All good. But, if I don't grap the lob output right away, and do some other
assignement work on the result before hand, the above explained issue takes
shape. The issue, after some testing, appears to be how the oci8 function
stores the clob resource. The following code results in this problem:
$query = 'select
id,
author,
cdate,
views,
title,
message,
top
from
APP_THREADS
where
TYPE = \'D\'';
$stmt = ociparse($fw_db-connection, $query);
ociexecute($stmt);
while (OCIFetchInto ($stmt, $row, OCI_ASSOC)) {
$messages[] = $row['MESSAGE'];
}
foreach ($messages as $message) {
var_dump($message-load());
}
with the output being:
clob4
clob4
clob4
clob4
In this example the lob resources are overwritten when you loop through
the result set the first time around, resulting in all fetched lobs
returning the value of the last lob in the result set.
The question is: is this an oci8 bug or just how things have to be done?
Thanks,
Michael
Re: [PHP-DB] Upgrading mySQL

RE: [PHP-DB] PHP vs ASP
These are some good points. My gut reaction is similar to Robby's, but here are the points he made: PHP = free ASP = not PHP = most widely used scripting language online PHP5 is out PHP = tons of open source libraries..free to download ASP comes free with PWS and IIS. So if you're already in a Microsoft environment, then PHP vs ASP as far as cost goes isn't a factor. PHP most widely used scripting language? I did some research on this (because I, myself, had a convince my Boss session a little while ago.. Which I'm never going to do, but I wanted to at least arm myself a little bit) and I found some surveys and the general breakdown seemed to be: IIS = 1/3 of the servers online (roughly) Apache = 2/3 of the servers online (roughly) PHP = 45+% of the primary scripting on Apache servers. Assuming ASP is used on 100% of the IIS boxes (or close to it), that puts PHP and ASP almost dead even on usage. I'm sure it sways depending on the survey, winds, alignment of the planets, etc. I don't think we'll ever get a fair, unbiased survey of such things. So that point is semi-debateable. The idea that they're neck and neck is encouraging though. PHP5 vs ASP, ASP.NET, or other current flavors of ASP.. I don't have direct head to head comparisons, but this seems to be a subjective measurement of worth. Tons of open source libraries,etc...There's a lot of sites devoted to posting code snippets and even full applications. Many for ASP as well as PHP. I think PHP's uniformity helps find useful code, whereas when I look for ASP stuff, I get ASP, ASP.NET (VB), ASP.NET (C#) and other mish-mashes of code samples. But there's certainly not a lack of ASP online resources. So back to Martin's post, these are definitely points to consider. Do you have in-house coders who already know something (that's the battle I fight right now. I'm the only PHP guy and we have at least two ASP.NET coders and another couple of VB or other MS based coders that could probably do the ASP.NET if needed.. So I'm outnumbered on that one). Do you have existing code that would have to be ported to PHP or would you have to support two different scripting languages (most companies prefer not to do this if they can help it). Will it be web based or do you desktop applications (where a VB.NET or some kind of Visual Studio compiled and developed application type language would be better than PHP... At least until WinBinder gets fully going hah). Server... Yes.. Do you already have a server? Do you have people that know Apache? Do you already have IIS running?If you're a small shop, these things could change on a whim, if you have a larger user base where even small changes can affect a lot of people, these can be very heavy considerations. I love developing in PHP, but there's no use trying to teach a pig to sing If you work for a pig, then you gotta learn to grunt and just use whatever they tell you to use. Don't force a change that's going to create a lot of problems, downtime, etc. Free is only free if you either don't have anything already or you have coders and servers that are already in-line with the new plan. If you take a bunch of ASP programmers and force them to learn PHP, then you have a learning curve, code porting and other things that can cost the company money and possibly create downtime or project delays. This makes Apache + PHP changover hardly free to the company. -TG -Original Message- From: Norland, Martin [mailto:[EMAIL PROTECTED] Sent: Monday, November 15, 2004 11:29 AM To: [EMAIL PROTECTED] Subject: RE: [PHP-DB] PHP vs ASP From: Perry, Matthew (Fire Marshal's Office) [mailto:[EMAIL PROTECTED] I need some ammo to convince my boss not to use ASP but use PHP instead.

[PHP-DB] IIS and php sessions
Hey everyone, I'm trying to migrate this php app with a mySQL database to IIS/Microsoft SQL Server. I know that I should be using a database abstraction layer but haven't had the time to do that just yet. In anycase, the question has little to do with that. I'm trying to get sessions in php working on IIS and I've noticed that that needs to be configured manually for IIS. But what exactly does that mean?

1. Ensure session.save_path is valid in php.ini (ensure the directory exists
and that's where you want to save session files)
2. Ensure the IUSR_computer_name user has access to read and write to the
directory in session.save_path. PHP runs as the IIS user when installed as a
module, which is the IUSR_computer_name user by default
3. Sessions should work. Run a simple test to find out.

[PHP-DB] PHP / Javascript question
Hi there everyone,
I have a form with check boxes and with PHP I use the array feature for the
form name. Now I need to check if the tickboxes are ticked and if not
return an error, normally with javascript I would use:
script language=JavaScript
function validate_form ( )
{
valid = true;
if ( document.removeitems.del.value == )
{
alert ( You cannot remove an item if it is not selected. );
valid = false;
}
return valid;
}
/script
BUT because the tickboxes information is stored in a PHP Array called del[]
I am having major problems getting it to work. Does anyone know how to
determine with javascript if any boxes are ticked, when the name for the box
is an Array such as del[] ??? Im grabbing the data from my MySQL DB
without a hitch etc . And I know technically this is more MySQL / PHP list,
but it is related and Ive looked online and cant seem to find anything, so
thought Id try here as usually you are all very helpful.
Thank you
Chris

Hey Chris
So, PHP creates HTML and Javascript on the server end. Javascript is read in
the browser. By the time the Javascript gets to do checks to see whether a
box is pressed or not, the PHP array is long-gone.
You should run your PHP, and then check the source code it makes in the
browser. What you'll hopefully see is a bunch of form boxes with the names
they got from the array. So, use Javascript to check those names.
If your list is dynamic, so there might be del1, del2, del3, etc., you'll
want to use a loop in Javascript to run through the names. To find out how
many there are for the loop, PHP can dump a javascript variable called
loopAmount or something.
Luck.
