[PHP] Encoding issue with £
This may be more of a mysql issue, but I am using php for my app so here goes... I have a fee field in the database, and when users post events they can specify entrance fee in £. In some, not all, of the fields I am getting, for example, £7 rather than £. Is this an encoding issue? Many thanks in advance... -- http://www.web-buddha.co.uk
Re: [PHP] Encoding issue with ?
Thanks guys. The issue is that users can specify text as well as currency in the input field ie '£2 students / £5 general admission'.
[PHP] Ongoing encoding issues
Hi all, I posted a question a couple of days ago regarding a web app I have wherein users are able to indicated prices and concessions via a text field, and the resulting encoding issues I have experienced, the main one being seeing the pound sign as £ if viewing the results in a browser with the encoding set to Latin-1. My question is, how do I overcome this. If I set my browser encoding to Latin-1 and enter the data I get that odd symbol, if I set it to UTF-8 I get clean data. Is there a way to sniff out what encoding the browser is using and then clean the data in any way. I am googling for help also but you guys have been so helpful in the past I thought I'd try you also. -- http://www.web-buddha.co.uk
Re: [PHP] php code to upload a url correctly

[PHP] Sorting a multidimensional array
Hi all. I am building an online events directory and as part of the system
users can search for events by date, category etc.
The logic involved in finding events that match the user-entered dates works
like so:
1. we create a range of dates from the start and end dates specified by the
user
2. we then poll the database for any events that encompass or intersect this
range (using the start_date and end_date fields from events table).
3. we then find out the frequency of the event ie weekly, monthly and then
map out its lifetime.
4. we then go through those dates, and for any that match a date in the user
range, the event on that date (ie all it details, name, venue, date, start
time etc) is added to an array.
...etc etc
So we eventually have a large multidimensional array whose elements contain
arrays of events that fall on a specific date.
I am using usort to ensure the events are sorted by date, but I also want to
sort by time, for instance if there are five events on one day I want to
sort them by start_time.
Here's an example of how the event array looks:
element [0] contains an array as follows ('date', 'name' venue',
'start_time', 'category...');
element [1] contains an array as follows ('date', 'name' venue',
'start_time', 'category...');
I tried using array_multisort but it didn't seem to do what I wanted. I want
to sort by date, then start_time if the dates are equivalent.
Any ideas?

http://www.web-buddha.co.uk
Re: [PHP] Sorting a multidimensional array
Thanks for that - can't do that as all I know in the database is the start
and end date for each event (so I don't have to create mapping tables and
perform massive joins), the rest is handle dynamically.
I think I can do it using usort, this seems to work, any comments?
function compare($x, $y) {
if (($x['date'] == $y['date']) && ($x['start_time'] ==
$y['start_time'])) {
return 0;
} else if (($x['date'] == $y['date']) && ($x['start_time'] <
$y['start_time'])) {
return -1;
} else if (($x['date'] == $y['date']) && ($x['start_time'] >
$y['start_time'])) {
return 1;
} else if ($x['date'] < $y['date']) {
return -1;
} else {
return 1;
}

[PHP] Problems processing UNIX timestamps in events directory
Hi all. I have an odd problem. I am building an events directory and when users search, they provide a date range ie Feb 16 2007 to March 12 2007 as one of the options for searching. The system then creates an array of timestamps from this and then polls the database for all events whose lifetimes (start to end data) intersect with or contain the user date ranges. The system then checks how many of those dates map onto the dates provided by the user and returns an array of events on specific dates, all by comparing timestamps. The system is working like a dream apart from the following. If the user selects a start date prior to March 26 2007 or after October 29th 2007 all is well. If they specify a start date after March 26 the events are not being pulled in. I have converted the user-friendly date output to timestamps to check and sure enough, when the user selects a start date before March 26 2007, March 26 2007 is output as: 1174863600 ...after that it becomes: 117486 ...a difference of 3600 Is this anything to do with leap seconds or any other clock drift phenomenon anyone has seen before? Much hair being torn out at present! -- http://www.web-buddha.co.uk
Re: [PHP] Problems processing UNIX timestamps in events directory
I AM using the logic you and Jochem suggest in the query, I am not performing any joins. I query for certain criteria re the start and end dates held in the database, and once I have my set I then work with it dynamically as I need to know, based on the event frequency, how many events from that range fall on dates within the user range.
Re: [PHP] Problems processing UNIX timestamps in events directory
Thanks all for your input - you're all correct, I don't really need to use timestamps as I am only interested in dates so will be reworking the app to use dates only. I still need to generate sequences of dates and really don't want to deal with DST, so my question is: can I add days to dates without converting to timestamp and adding 86400 for example. If I can it will make things much simpler. I am talking about doing this dynamically with php rather than at database level. Many thanks in advance, I will also start googling... -- http://www.web-buddha.co.uk

OK. Blank entries means that as date is passed in and validated via forms, it is then entered into $_SESSION so data can be persistent as the user goes back and forth. These values are eventually entered into the database and are blank, whereas the few values that are entered from $_POST (ie credit card numbers that I don't want to carry around in the session) are fine. The system works in IE7, FF and Opera and has also worked on my local version of IE6.

Re: [PHP] Intro to PHP question

Why not learn in a web environment if your goal is to build a website? Just create the following file: save it, upload it and view it. If you see the php details you have the system set up as you need it and can just start writing php-driven web pages (the file you are using now is one!). If you really want to run that on the command line, you will need the path to php on the first line of the file. Please, forget the command line stuff unless you want to write command line scripts, and get that file running in a web environment where it belongs. happy to help if you need any more assistance doing that!
[PHP] Variable variables and references
Hi guys, I have just read 'Programming PHP' (O'Reilly) and although I think it's a great book, I am confused about variable variables and references - not the mechanics, just where you would use them. The subject of variable variables is explained but no examples are given as to why and where you would utilise them. As for references, the examples given with regard to passing and returning by reference in functions is clear, but no real examples are given as to when this would be a preferred approcah - in fact, the authors stress that due to PHP's copy-on-write mechanism, it is not a frequently-used approcah. So my question - are there any 'classic' situations in which either should be used, and where and when do you guys use them in your real-world efforts? -- http://www.web-buddha.co.uk

Turn off register_globals - if you pollute your scripts with global

clean the variable.
Using include("$page.php") is asking for trouble.
If you can get register_globals switched off (it's off by default in PHP5
for this very reason) then use the kind of security procedure so well
explained on brainbulb.com (also well worth watching the audit cast):
Maybe something like:
$page = isset($_GET['page']) ? trim(strip_tags($_GET['page'])) : 'page';
// clean data here, ie check suffix, reun tests, and only then...

...you are running the query and assigning the results into $sql and then

Re: [PHP] Re: CSS vs. Tables OT
Tables used for presentational layout are a hack, implemented in an albiet ingenious way to overcome the shortcomings of the Web quite a while ago now. Tables should be used for the display of tabular data, ie spreadsheets, calendars etc. Table layout increases download times, the deeper nested the worse it becomes. They compromise accessibility and the semantic structure of the content, and confuse screen readers and search engine bots. Clearly laid out with the proper use of captions, summaries, headers, etc for tabular data they are a beautiful thing. CSS layout is possible, faster, easier to maintain, more flexible and more accessible and the situation is only going to improve. The pain experienced by old-school designers at making the transition is understandable, but necessary. At the moment it's a subject of hot debate, but the tables-for-layout crowd are going to be increasingly marginalised as we move forward - and this is the way it should be as we try to evolve the web.

Re: [PHP] http_request
It's advisable as the page you will be redirected to will be relative to the one the browser actually requested, so it's a good habit to get into.

Re: [PHP] More frustration with MySQL and PHP
Don't be scared of functions, no magic or mystery there, all you are doing
is putting your code in a function like so:
function add($a, $b) {
return $a + $b;
}
..for example and calling it like so:
$a = 12;
$b = 100;
$sum = add(12, 13);
...etc etc, not too much more to learn than that and now I can call add() in
many places...

Re: [PHP] Question about functions
Methink you're a little confused. A function is a piece of code that
performs a specific job that can be called. You may send it
data, you may not. It may return data, it may not. If your link goes to
logout.php, that script may use functions to do it's job.
You can't call a function in a link as php is server-side. What you are
thinking of is an event handler, ie client side (javascript).
Example of how you could achieve what you want:
logout.php
include 'logfunctions.php'
logout($_GET['id']);
header("Location: index.php");
exit();
logfunctions.php
function logout($id) {
unset($id);
}
etc etc etc - crude example but pushed for time and you get the idea!

[PHP] IE and cookie issues in PHP app
Hi all. I have built an online events directory in php (
http://dontjustsitthere.co.uk) where people can find local events and also
post their events. The app is composed of a single page, index.php, that
generates different content depending on the parameters passed to it and
uses sessions for persistence.
I have had nothing but pain with IE6 with this, I don't use any third-party
cookies and one issue was resolved by using this line at the top of the
page:
ini_set('session.name', 'couchy');
session_start();
To post an event, the first form processes the category and postcode of the
event plus a captcha field. The fields are validated and cleaned and then
passed into $_SESSION.
On the next stage I perform a cookie check, and if there are issues warn the
user. This has been happening to every IE6 user, they can't get past the
first page - so that means that $_SESSION['category'] and
$_SESSION['postcode'] are not being populated.
I thought I had this nailed but it's rearing it's butt-ugly head again.
Anyone aware of the probable cause of this?

Try it the same as the php manual page:
$conn = mysql_connect('');
if (!$conn) {
die("Could not connect: " . mysql_error());
}
You may be logging the errors. Tty echoing the value of the resource
($conn) - it should be an integer.

$item[] = $_POST['category'];
$item[] = $_POST['copy'];
$item[] = $_POST['pic_style'];
$item[] = $cost;
$item[] = $image;
session_register('item');
In the session the item is known as 'item'. What I need for it to be is
'item1' so when the customer chooses another product I can increase $count
by 1 and have the next array with values stored as 'item2'.
Thanks for any help,

First off, don't use session_register, use the $_SESSION superglobal
array, that way you can create:
$_SESSION['count'] = 1
and increment like so:
$_SESSION['count']++
then you can create the cart like so:
$item{$_SESSION['count']} = array();
does this make sense. Maybe not, but then again I've had far too much
coffee. Make sense to the php gurus out there?

Re: [PHP] Regular expression to find from start of string to first space
On 08/08/06, Dave M G <[EMAIL PROTECTED]> wrote:
PHP,
Shouldn't this regular expression select everything from the start of
the string to the first space character:
$firstWord = preg_match('#^*(.*) #iU', $word);
It doesn't, so clearly I'm wrong, but here's why I thought it would:
. stands for any single character, not *. Also, # is the delimiter, but
you can use a variety of deliimters. The following should work:
^[\w\d]+\s{1}
^ start of line
[\w\d]+ range of any digits or letters, one or more
(\s{1}) exactly one whitespace character
hope this helps!

Re: [PHP] break up variable and put each element in an array

A. I have a page on which people can supply dates in a text area. Dates
are
entered like this:
3/01/2005
29/12/2005
2/01/2006
20/02/2006
28/12/2006
1/01/2007
15/02/2007
B. Now I need this Post element to be broken into pieces (per date) and
each
of those pieces should be put into a text so the outcome (echo on screen)
would be like this:
Date=3/01/2005
Date=29/12/2005
Date=2/01/2006
Date=20/02/2006
Date=28/12/2006
Date=1/01/2007
Date=15/02/2007
The posted variable from A looks like this (when written on screen):
3/01/2005 29/12/2005 2/01/2006 20/02/2006 28/12/2006 1/01/2007 15/02/2007
So I need break this up and store any individual date into a key of an
array
Afterwards I need to loop through this array and use the value of each key
to be printed after 'Date='
try this:
$string = "3/01/2005 29/12/2005 2/01/2006 20/02/2006 28/12/2006 1/01/2007
15/02/2007";
$array = explode(' ', $string);
foreach ($array as $value) echo "Date: $value";

Hi,
How do I add so that it checks for a comma , in this preg_match. I think
the
documentation is not that good for the pref_match:
preg_match('/^[a-z0-9-_\'() +]*$/i', $s);
Check for a comma inside a range - use a comma!

It was that it was not suited to me, and that I actually just wanted to find a solution to my problem directly, and it did not give me that. I have never worked with Regular Expressions before, so I might need to do some more research on that, it seams to be a good tool :) I will do some testing in the CMD to learn how to use it, should not be that big of a deal :) Many times the regex looks like rubbish, but that is just because I do not know the "language" :) Indeed - remember, regex is a language all of its own and it takes a while to get comfortable with the syntax and think in regex. The Regex Coach is great by the way. Also, when you build expressions, build them up slowly, testing each part as you go.

Yep. The PEAR XML_RSS class.
for example:
$feed = 'foo.rss';
$rss =& new XML_RSS($feed);
$rss->parse();
foreach ($rss->getItems() as $item) {
// output rss

[PHP] Include and require
Hi all - I have several require_once statements in my web app to load in small function libraries. A common one bundles a variety of functions to handle date math and map month numbers to month names. I originally defined an array in that file plus a bunch of functions but when I loaded the page, the array variable, referenced further down the page, was NULL. I wrapped a function def around the array and returned it and all was fine. I may be suffering from mild hallucinations, but can you not define variables in a required file? It is not a scope issue as the array variable is referenced in the web page, not in any function. -- http://www.web-buddha.co.uk http://www.projectkarma.co.uk
