At the moment you're using integer values to describe the attribute type. Whilst this may be fine for your code, I've often found that people like to edit values in the database directly because it's faster, and you could end up with issue if they put the wrong values in the wrong places. I believe MSSQL (which is what I think you said you were using) has caught up now and has an enum field type which would allow you to use string values in your queries, but internally they are still stored as a very small integer (tinyint or the mssql equivalent iirc) which will save on storage space. I often do this for database fields (in MySQL) where I know a field will only ever have a limited range of values, as it sure helps. This is unless of course the integer value is actually the index of another table indicating the type, in which case ignore what I said! Thanks, Ash http://www.ashleysheridan.co.uk

Re: [PHP] Date Conversion Problem
David,
I think it would help people like me (newbie) to know the exact statements.
Though I could envisage what you would have done with my current learning,
it would be good if I double check the statements that went there to fix
it.

[PHP] Character Encoding for em-dash
Hi All, My client has a database (Sybase) in which a table column URL contains a string like- http://www.pjonline.com/cpd/nutrition_ _drugnutrient_interactions The box like un-recognized character is emdash. I need to display the data on the web lets say in a HTML page where box should be decoded somehow to be displayed as emdash. We cant change anything in the dataabse as such. So anything we need to do has to be done on the fly. I have tried using online tool like http://2cyr.com/decode/ which just converts the string to a best match decoded string and also displays box as emdash!! This means we can do something in PHP to convert the box to emdash somehow. Is there any possibility in php to convert to real emdash? I have alreasy tried urldecode, mb_convert_encoding etc. Also the interesting thing is that "http://2cyr.com/decode/"; website says that the string is of encoding hp-roman8! I want the string to look like- http://www.pjonline.com/cpd/nutrition_-- _prescribing_parenteral_nutrition.html Any help? Thanks, Gaurav Kumar

RE: [PHP] Unit testing in PHP
From: vikash > What do you use for unit testing in PHP? phpUnit, SimpleTest or any other? I use Mike Lively's "PHP TAP Test Harness" with test-more.php from the "Apache Test Harness." This requires a CLI interpreter be installed. I was already familiar with the equivalent packages in Perl, and this is mostly a port of them into PHP. In addition to that, I have written my own db_dummy.php to emulate the PostgreSQL library in PHP. I have no class, so the OOP test modules are of no use to me.

Mock Objects and the Web UI are IMO, way better than what they are with PHPUnit (the last I saw of it). Besides, everything comes as a package => much easier to set it up. As far as CI-tools go, phpUnderControl supports only PHPUnit (out of the box). Phing supports both PHPUnit and SimpleTest painlessly. -- Best Regards Pavan K Murthy http://grahana.net/ signature.asc Description: This is a digitally signed message part.

The "fix" is most likely to be ...
1 - Convert the string date using PHP's strtotime() function to
populate a new column on the DB.
2 - Find the code that inserts/updates the date string and add the new
column to the insert/update statement.
That will preserve the current app and allow you to have the new
column for new work.
Just remember, if _YOU_ update the new column, you must also update
the original date string also.

When a visitor closes their browser, or stops the page from completing its loading, no message is sent to the server, so your PHP script won't know about it. The only way I know of currently to check for this is use some form of regular check-in, with Ajax or something, that calls home at regular intervals to inform your script that it is indeed still connected.

RE: [PHP] Date Conversion Problem
Here's my approach to this problem, and how I am planning on fixing this - tell
me what you think if this will work...
I need the format in the database to be "1/14/2010 3:25:58 PM"
There's not a ton of records that need to be updated, so I was going to:
1) Change the PHP function that is writing the date format incorrectly to the
above format
2) Then manually go through the records and update the incorrect dates
3) Then change the datatype in the DB for that column from varchar to datetime
Far as I can see, this should work.
This is why I hate inheriting other people's stuff...not to mention I'm a
newbie, so that doesn't help ;-)
Thanks!

The "fix" is most likely to be ...
1 - Convert the string date using PHP's strtotime() function to
populate a new column on the DB.
2 - Find the code that inserts/updates the date string and add the new
column to the insert/update statement.
That will preserve the current app and allow you to have the new
column for new work.
Just remember, if _YOU_ update the new column, you must also update
the original date string also.

Having said that, you will have some serious issues is your dates are
generated from around the world and not purely in your local timezone.
A lack of timezone (Europe/London, Europe/Berlin) rather than the
timezone offset (+1:00, etc.) is the issue here.
Due to DST changes not being consistent worldwide, with the timezones
changing over time, etc. All quite complicated.

Under normal conditions, you would store the date in a datetime
column. That allows you to do all the date range work in the DB.
When you display the date, you would use PHP's date() function for
format it appropriately.
date('l jS \of F Y h:i:s A', $row['fieldname']);
sort of thing.

It's best to store the date as a date rather than a string, as it avoids the
sorts of problems you're seeing now.

[PHP] Date Conversion Problem
PHP newbie here...
I have some PHP code writing the date/time into a MS SQL 2000 database
like this:
date('l jS \of F Y h:i:s A')
So the text it writes into the DB is like: Thursday 15th of April 2010
10:13:42 AM
The database field is defined as varchar, not datetime...so it's a
string essentially...
How in the world do I do a date conversion on this? I've tried things
like:
select * from table where convert(datetime,fieldname) >= '6/10/2010'
(where fieldname is the string in question)
Which results in "Syntax error converting datetime from character
string."
So I guess I have two questions:
1) Can I write a SQL query that will convert this properly into a
datetime?
2) If not, I guess I'll need to change the code to write the date
differently into the system, how should this statement be changed to
allow for proper conversion? date('l jS \of F Y h:i:s A')
Thanks for any help!
