Has anyone used any of the following frameworks? What is the general
opinion of using frameworks etc?
WASP - http://wasp.sourceforge.net/content/
Symfony - http://www.symfony-project.com/
Prado - http://www.xisc.com/
WACT - http://www.phpwact.org/
CakePHP - http://www.cakephp.org/

I haven't used them, but our local user group recently had a meeting
on PHP frameworks[1]. The feeling of the people that have used them
was that Symfony was a good project, and that CakePHP was a
particularly large installation. No one mentioned having used Prado,
WACT or WASP.
We also had the creator of PHP on Trax present on the framework he
created that very closely resembles Ruby on Rails. His company used
Trax to build KatrinaHousing.org, a site that helped hurricane
victims find housing. I have a copy of his (John Peterson's) slides
on my website[2].

You could start with list($t1, $t2, ...) instead. Personally, I'd done
it without assuming mysql_fetch_row is returning an array.
Try:
$t1 = "";
$t2 = "";
while ($row = mysql_fetch_row($result)) {
list($t1, $t2) = $row;
...
}
echo $t1;

Hallo,
I am adding a value to a session variable (an array). Then I want to place
the key of the array in another session variable to keep it for later use
(so I can return to the array to write data to it). The key function should
work there, but it seems to be a bit strange.
Imagine:
$array = array();
$array[] = "Yellow";
$array[] = "Geen";
$array[] = "Red";
foreach ($array as $key=>$value)
{
print ("Key: " . $key . " has color " . $value . " | ");
print ("current key = " . key($array) . "<br/>");
}
If you run the loop the key value returned from key is one higher than the
key in $key, and the last key is null?
How do I get the present key without a problem??
Thanks!!

You've already got it in $key. I think you will find that foreach advances
the internal array pointer by one each time it loops, so what you have is
key($array) looking at the next array element from the one in $key and
$value.
Nothing wrong with key(), just a misunderstanding on your part about how
foreach works :-)
In simplified terms, the first time through the foreach loop, this happens:
pointer at element 0
$key gets value 0
$value gets value Yellow
pointer moved to element 1
Then you use key(), which gives you - guess what?

Hi all,
I am writing my first website in php. I have a few questions.
1) I need to do vaildation on form values that I have entered into a
form. Is there a way I can write the vaildation code on the same page
as the form in php?
2) I have a drop down menu on one of my form fields. What I want to
do is if a certain item is seelected I want to have a new textbox
appear below the drop down menu. Is there a way to do this in php?
Thanks

Yes there sure is. :)
if (isset($submit)) {
// data validation etc.
}
else {
// display html form
}

You'll have to do this via JavaScript. =/
Hope that helps!

Yes. What you do is check to see if you have any input, if not then
display the form, if you do then validate the input and skip the
display.

It depends. If you want the text box to appear immediately then no,
you'll need JavaScript. If you're ok with the user hitting submit and
being re-desplayed the same page, this time with the text box showing,
then that is trivial in php. You can use the same process as the
validation in (1) above.

I send out a daily email to an email list. I have only been doing this for
about a week, and realized today that each one of them so far has had at
least one mysterious exclamation point somewhere in the email. This is
sometimes in the middle of the word or sentence, but always out of place. I
have tried replacing my quotation marks with single quotes, ", and
adding a backslash before them as I was told the issue had something to do
with these, but none of this has helped.
So first question.How do I lose this exclamation point?
And second questions.Is there anyway around changing my quotation marks to
something else or is that just part of it?
Thanks,

Hello!
I have a database and php classes and I'm not sure the best way I
should be retrieving the data.
as below, if 'other' (line 9) is stored in the database as an id of a
record in another table,
should my getData() method:
a. return the id as part of the MyObj object and whatever function
that called it is responsible for matching the id to the name?
or
b. should it look up the value from within the class?
(I read something about JOIN or stuff beyond SELECT --sorry i'm kinda
just getting into this-- could bring a database to it's knees)
Also I thought that with OOP you are supposed to keep the classes
independent of each other, but I was thinking if I need a MyObj I
would want all the data in a ready usable form and not a mix of data
and database ids.
I'm not sure what is the best practice or even if there is a correct
one, but suggestions would be appreciated!
-robert
here is my set up:
DATABASE:
myobj_table with id, name, other as columns
other_table with id, name as columns
PHP CLASSES:
1: <?php
2:
3: /* base object data structure */
4: class MyObj {
5:
6: function MyObj($id, $name, $other) {
7: $this->id = $id;
8: $this->name = $name;
9: $this->other = $other; // ?? ID OR VALUE ??
10: }
11:
12: // getters/setters
13:
14: }
15:
16:
17: /* create/update/delete database methods */
18: class MyObjData {
19:
20: var $_id;
21: var $_items;
22:
23: function MyObjData($id) {
24: $this->_id = $id;

26:
27: function getData() {
28: $query = "select * from myobject_table where id='" . $this-

29: $records = getDatabaseRecords($query); // some db action:

imagecreatefromjpeg takes a *filename* not the actual contents of the file
itself. So $image is going to be invalid so your next command isn't going
to do what you think which means you're going to get black as that's
probably the first/default color of $image_p.

Help, I can't find anything on this.
I upgraded from apache 1.3 to apache
2.2
My problem is, I currently have .htm files being
parsed as php, that works fine.
However, if I have the php_engine turned off for a
directory, any .htm files will now prompt firefox to download it.
How do I stop this? I need to keep .htm files
parsed for php, but I also need to be able to turn php off for certain
directories and still allow regular .htm files to be seen.
Thanks.
