completely compatible.

Unescaping An Escaped Entry
how to unescape an escaped database entry if that makes sense. When they fill out a comment form, it shows up with words like..."that/'s the reason I/'m doing this" if that makes sense. i want to remove the "/" and I assume its doing that b/c I had to escape the text box when they enter info into the database.

How To Search Strings Escaped By Mysql Real Escape String()?
I am currently developing an article script and there are Titles and Contents. To prevent sql injection, people say we must use mysql_real_escape_string().

So let's say if there is a Title that says "My Friend's best friend", if I look into the MySQL table record, the text will be saved as "My Friend's best friend", where the apostrophe is escaped. Code:

Unescaping Characters In Flat Files
I'm making a modular website using flatfiles (can't use mysql) and I realized I've never done a flatfile before (too much mysql) and I realized I'm having issues with quotes
like if i say "data" it returns as "data" I know i can do a stringreplace on the out put to remove slahses, but there is a lot of characters to escape any tipsideas on making it easier on myself?

Escaped Or Not?
I have magic_quotes on. Therefore, backslashes are added before single quotes after a form is submitted. When executing a mysql_query, data is inserted into DB without problems.

I remember that some time ago, my single quotes (and of course some other characters as well) were kept escaped in the DB. I could see that when I looked in phpmyadmin at the table records.

As of now, my data is kept as it is, as it should look in the DB when I look in phpmyadmin. No escaped characters. As far as form injection and security is concerned, is this safe? How do you keep your records?

The Amazing Escaped Single-quote
Say you have a form with a textarea. Say you type something with single-quotes (e.g. I'm happy so I'm sad) in the textarea. When the textarea is POSTed to a PHP program, are they escaped with the backslash?

I ran it on two different servers and one did and one didn't. Why is this? Is there some setting somewhere? Or is this a version diff thing? Here is the PHP code (I changed all angle brackets to square ones so it'll appear): Code:

How To Get Un-escaped Text From A Form Field
I have a php script that gets the text from a form field:

<?php

include("global.inc.php");

pt_register( 'POST', 'test1');
echo $test1;

?>

The text comes back fine, just some characters (', " and ) are now escaped
(', " and ). The problem is that I need the he text to be exactly as it
was entered by the user. I could process the text myself, and replace the
escaped characters, but I'd like first to understand why this is happening
and if there is a way to disable this behavior and get the unmodified text
directly.

Find A Single Or Double Quote In $desc That Was Not Escaped.
I am having problems getting php to escape characters, so I can use them with javascript. Here is the code. PHP Code:

$desc = $item['description'];

$desc = str_replace("'", "'", $desc);
$desc = str_replace('"', "'+String.fromCharCode(34)+'", $desc);

echo "<a href='index.php' onMouseover="showTooltip(event,'$desc');return false">Link</a>";

I am trying to get a tooltip to work. It seems to work most of the time, but sometimes the tooltip does not work, and when that happens I can find a single or double quote in $desc that was not escaped.

PostGreSQL INSERT
I've written some scripts to display information from a PostGreSQL database in a table format, and everything is fine. I've been adding data manually up until now. So, I've written a page where users input their information and this gets inserted into the relevant table. However, this isn't working.

I have been chopping code out to the bare minimum just to get something working, but even the simplest thing doesn't work.Here's what I've got at the moment :

$resultSet = pg_exec($conn, "INSERT INTO ntable (make, model) VALUES ('Suzuki', 'Bandit'))";

I have connected ok, so there's no problem there, but the above line produces :

Php And MS-SQL And PostgreSQL (with Apache)
I have an architectural type question that centers around php.
We have a website that people hit that uses php to dynamically
generate
web pages. We use Apache and php (although we don't have php compiled
in with apache). Our Unix like server (FreeBSD) that has php (and
Apache) on it that today communicates with the postgresql database on
another Unix like server (Linux). I configured the php set of
libraries with postgresql support in them.

(Unix server) (Unix server)
[Apache + PHP ] -----> [ postgresql ]

- (Win 2003)[color=blue]
> [ MS SQL 200 ][/color]

We are adding a Windows server into our system that contains MS-SQL
2000 on
it with another database to interact with. My question is to access
both databases from the php server (freebsd), is it only a matter of
compiling php with postgresql and mssql support in it or are there
other things to consider? I know there are different function calls
for each database type and even a PEAR interface that handles
different databases with a common interface. I am just looking at my
configurtion options/possibilities.

Cannot Connect To Postgresql
I am running on Win XP. I have installed Apache 2.2. Works fine.
I have installed php-4.4.4-Win32 manually.
Apache to php connection is working fine, I tested a couple of trivial
php scripts.

I have installed PostGreSQL v8. I can do stuff (create table, populate
data) thru pgAdminIII tool, so I think that is also fine.

I want to install phpBB. When I try to do the set up I get message
"The PHP configuration on your server doesn't support the database type
that you chose"

So it tells me the issue is with php and PGSQL, hence my question here.

I have modified php.ini to uncomment the line
extension=php_pgsql.dll
and restarted the server. No good.

I tried running this script that I copied from a site
<html>
<head>
<title>PHP Test</title>
</head>
<body>
<?php echo '<p>Hello World</p>' ?>
<?php $conn = pg_connect("host=localhost port=5432 dbname=postgres
user=postgres password=mypasswd");
$sql = "SELECT current_date AS today;";
$result = pg_query($conn, $sql);
$row = pg_fetch_object($result, 0);
echo "Today is: " .$row->today;
?>
<?php phpinfo(); ?>
</body>
</html>

It prints out the Hello World line. Doesn't print the phpinfo. Nor
the current date.

Needless to say, I know no php, just want to get the bulletin board up
and running on my PC.

Too Many Connections To PostgreSQL
I'm running into a problem wherein I'm unable to connect to my postgresql db because the maximum number of connections has been reached. I use ADOdb for my db work, and the thing is I'm using the PConnect function, so it's supposed to be using persistent connections.

Since this is the case, I find it very strange that I'm having problems with the number of connections to postgresql. Also, I'm the only one using Postgresql on this server (a test machine) and I'm working on one area of my project (two or three pages) so it should definitely be reusing the connections.

New Stuff In PostgreSQL 8.1
what new stuff in PostgreSQL 8.1 are you looking forward to? Moving pg_autovacuum into main sounds pretty significant. I guess I can remove my cron vacuums? The replacing of users and groups with roles sounds pretty significant too. wonder if I'll have to worry about that. The csv header option is a nice small touch. Looks like there's some new IN/INOUT functionality for plpgsql that may replace RETURN. Other than that, it appears there are also quite a few performance improvements.

Getting Off The Ground With Postgresql
I have managed to install postgresql on my server and i've successfully added a database and user. HOWEVER, i can't figure out how to setup Postgresql and phppgadmin to work together. Ivisit the phppgadmin page which seems to work and prompts me for login but then i cannot log in no matter what.

I checked the postgresql log file and it appears that postgresql is trying to use an ident server which i don't think i have. I've seen some docs that talk about making changes to pg_hba.conf but this looks a bit scary to me. I'm accustomed to the mysql/phpmyadmin approach which has a root user who can create databases and user accounts with access to them. I'd rather not have 'trust mode' on if I can help it as that sounds a bit like a security risk.

Sort Of Bugzilla In PHP/PostgreSQL?
I've now become a HUGE fan of PHP and PostgreSQL on Red Hat 9. We're
moving everything we can to it as fast as humanly possible in the next
2 years. Some other things we do are moving to Progress/Webspeed on
Linux and AIX.

Do you know of anyone out on the web who has made a kind of
Bugzilla-knockoff (even primitive) and has implemented it in
PHP/PostgreSQL? (Bugzilla is user-friendly and was written in Perl.
It's also quickly becoming the industry standard among non-MS
programming circles.)

Can you show me a website demo? If I get to see some of these, I might
be able to convince my boss to purchase a copy to install here and
then customize for our environment. (Can't promise this, however.)

I would code this myself, but I have been so under the gun to get so
many other projects out the door. (Heck, I might even need to fly in a
temp PHP programmer to come in and help me with all this other stuff I
need to build, but again -- I can't promise anything.)

So, if you're a PHP entrepreneur, get cracking! :)

Query Problems With PostgreSQL
I'm having intermittent problems with queries from my php script to a
postgresql database.

I have a form where I can enter a search query - for instance a last
name. This leads to a results page with a brief bit of information
about each of the matching results. From there, I can click a link
associated with any of the results which takes me to a page with all of
the details. Pretty standard stuff.

Problem I'm having is that for some of the results, when I click the
link to go to the full details page, no information is returned by the
script. I basically end up with my html template & no data populated.
For the majority of items, things work just fine.

One thing I've noticed is that it seems to be reproducable - that is,
for example item 5123 always fails to return any results on the full
details page.
