barophobia wrote: I only know of one reason to submit a form as POST and that is because you can submit more data in one shot. What other reasons are there? The difference between get and post is not what you *can* do, it's what you *should* do. Get, as the name implies, should be used when retrieving a page. The URL, including the query string, should contain info needed to retrieve the right page. No significant changes to either session or persistant data should be made in response to a get request. Post is used to send data to the server, and should be used when modifying something. That something could be 'the logged in user' (in the case of a login form), or 'a blog entry' (in the case of a blog entry editor form). Put more simply, get requests should not make significant changes to the data or state of your website, always use post requests for that. These implied "rules" have existed since HTTP was invented, and when you think about it they make a lot of sense. They also get emphasized by the existance of so-called web accelerators that simply pre-fetch URLs on the page the user is viewing. If you have simple links (i.e. get requests) that make changes to your websites data or state, the accelerator will seriously screw it up. As an illustration, consider a blog editing app. You log in and view a list of entries in your blog. Each one has edit and delete links next to them. These are plain URLs. The delete link uses javascript to ask the user for confirmation. The accelerator happily goes through these links, helpfully pre-fetching them for you. This is fine for the edit links, but the delete links cause the website to delete your entire blog. Oops.

This is a terrible waste of bandwidth. So the "accelerator" downloads 50 pages linking from the first page you hit and after spending 5 minutes reading the first page you decide not to visit any of the other links.

Re: [PHP] PHP textbook suggestions?
I'd still like some actual recommendations for a good book for beginners. My "PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide" has already been mentioned by someone and gets good reviews. If you want something more basic, I wrote "PHP for the World Wide Web: Visual QuickStart Guide" for the non-programmer. It goes at a much slower pace but obviously doesn't cover as much. Although neither is technically a textbook, both are used as textbooks in high school and college classes. For a recommendation without the self-interest, the Thomson and Welling "PHP and MySQL " (Sams) is a very good book (I forget the title, but it is good and thorough). Whatever you look at, make sure you get the latest editions. I know that Amazon doesn't necessarily offer up the latest edition of a book, so you sometimes need to click on "All Editions" to see if it's been updated.

[PHP] Re: PHP4 vs PHP5
In my opinion, it is very safe to go for PHP5 (it's been out for a long time now). Also, PHP5 has a lot of built-in functionality that you will definitely feel you're lacking in case you go for PHP4. And don't forget, PHP4 will be deprecated sooner or later (I'm sure the developers will not really like the idea of maintaining 3 PHP versions once PHP6 is released). All in all, PHP5 is a very wise choice at the moment. -- itoctopus - http://www.itoctopus.com ""Fernando Cosso"" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi > I know this topic has to be discussed several times but I have a situation I > need some advices. > > I am working in a small company.

Not only your method may count some links twice, but it will count wrong
URLs also.
External is not a URL that will
take someone externally.
Below is the function is_url

[PHP] Help with table in database and login scripts.
Team,
I want to know if my table is setup correctly.
I am creating a site where team owners control fantasy football teams.
Imaginary teams. They can trade players, add and drop them as long as
they are under the salary cap at all times. if not they are given a warning
to make a different move or something along those lines.
I have created a table for league_members.
Can you tell me if I have this set up correctly.
This will be for the register.php form
Field Type Attributes Null Default Extra Action
fantasyteamname varchar(30) No
firstname varchar(20) No
lastname varchar(30) No
username varchar(10) No
emailaddress varchar(50) No 0
address varchar(50) No
city varchar(30) No
state varchar(30) No
zipcode tinyint(5) No 0
homephonenumber tinyint(4) No 0
mobilephonenumber tinyint(4) No 0
favoriteprofootballteam varchar(50) No 0
favoritecollegeteam varchar(50) No 0
Then once register they should be taken to login screen then once logged in
they should be taken
to their team page IE cougars.php or something like that.
Can you all please give me a how to write a script on that and let me know
if I did the table right?

[PHP] Design Dilemma - Database Data Abstraction
I have a dilemma on a design where I humbly ask your help. I'm working on
the model part of a web application (not to be understood in the "web2.0"
way, but in a more general way, where anything mounted on HTTP is a web
application) done in PHP5 following the MVC design pattern. But the strong
point is that the result must be those-who-never-RTFM-proof. But that's not
my dilemma, I only mention this so that no RoR concept or similar is thrown
into the table, that is, NO ActiveRecord.
The solution I presented is to access, and act upon, a database as if they
were PHP arrays, meaning that a table is presented as an array of records.
Here comes my dilemma. But first let me explain a bit about the scenario so
far:
* It's aceptable that some restrictions are set upon the DB structure, only
if at least the following constructions are allowed:
a) tables with only one field in the PK (usually an autonumeric int).
b) tables with a one-to-many relationship with itself, and one field PK (a
tree structure).
c) tables with a one-to-one relationship, and at most two fields in the
PK, and if there are two, one is a FK.
d) tables with a one-to-many relationship with one of the before mentioned
tables, at most two fields in the PK, and if there are two, one is a FK.
e) tables that create a many-to-many relationship between two of the
before mentioned tables, with possibly extra fields other than the fields of
the relationship, at most three fields int the PK, and if there are two or
more, two of them are FK.
* The actions than will be more used to access the data will be:
a) get one record using its PK, or a combination of FKs where it applies.
b) get one record using a unique key.
c) update or delete one record using its PK.
d) insert one record
e) loop on many records of one table, all or just one "page", or those
related to a FK.
f) order the records before the loop
My dilemma is as follows: a PHP array is a construct more restricted than a
DB table. In a PHP array the index is either an int or a string, in a table
de index can be any combination of fields. Then, my problem is how to design
coherently the indexing of the arrays that represent the DB tables.
I could index by the order as they are presented by the DB:
$DB['users'][0] is the first user from the query "SELECT * FROM users"
$DB['users'][1] is the second user from the query "SELECT * FROM users"
etc..
But this have many cons. First, without a deterministic order, the array can
change its logic order on the whim of the DB, nobody assures that the order
will be kept after a modification is made to the data, and this can be
confusing and error prone:
$name1 = $DB['users'][3]['name'];
$name2 = $DB['users'][5]['name'];
$DB['users'][3]['name'] = $name2;
$DB['users'][5]['name'] = $name1;
The last sentence may not be writing to the adequate record.
But this indexation has its pros. It can be used with a traditional for loop
(although it will prove inefficient in most cases). And the records after
and before can be easily obtained.
Another possible indexation could be by the value of the PK, but this also
have some problems. First, it can be confusing if the PK is an autonumeric
int, as this might be seen as a numeric indexation. Second, not all tables
have only one field as PK (I can ask that all tables have at least a PK, but
I can't ask that the PK is made of only one field).
But I have many pros with this strategy. I solve the actions on one record
using the PK (only if the PK is made of only one field):
$user = $DB['users'][$userid]; // get
$DB['users'][$userid] = $user; // update or insert
$DB['users'][] = $userid; // insert
unset($DB['users'][$userid]); // delete
I think I could use other than ints and strings in the array index, but I
rather stick to keeping this as seemingly equal to PHP arrays. I also could
use FK relationships to solve this, for example, if tone table has an index
made of two fields, one is an FK to another table, I could make one table
look as an array inside the other:
foreach ($DB['users'][$userid]['address_book'] as $address) {
...
}
In this case address_book refers to another table rather than a field (I
would have to ask that there are no fields with the same name). This table
has an FK to the id of the users tables and one other record working as a
PK. Accesing the array this way I have one of the values of the PK (the user
id), and I use the other as the array index.
There is also the problem with many-to-many relationships. If there was only
one table that related two tables in this way, I could do the following:
$DB['users'][$userid]['groups'] <- groups where the user belongs
$DB['groups'][$groupid]['users'] <- the users of a group
There would be a third table other than users and groups which doesn't show
up. But, what to do when there is more than one relationship table for the
same two tables? And if the relationship table also had some extra fields?
Also the delete action presents some problems:

I have a problem,
I need to turn an iterator into an array, but when I do, some methods I

//$files = iterator_to_array($files);
foreach ($files as $file) {

It works as expected. However, when the iterator is turned into an array:
$dir = 'c:/';
$files = new DirectoryIterator($dir);
$files = iterator_to_array($files);
foreach ($files as $file) {
echo "{$file->getFileName()}"; //does not work
echo "{$file->getPath()}";//works
}
It stops working. Can someone please help me, as a have tried and failed

I'm not sure if it's possible, it depends on the setup of switches
etc. You're remote connection is outside your LAN right? If so, then
your IP address is assigned by your ISP, this is assigned for each
connection. I guess you have more then one connection from your ISP,
then you have more then one IP. So if you have more then one
connection, you have more then one modem/router. So if you want to use
the IP of another connection, you should connect through another
router/modem. But this depends on your setup, and has nothing to do
with PHP.

Re: [PHP] Re: PHP4 vs PHP5
Although I rarely post here (mostly lurking)... I would think that the mere fact that support for PHP4 ends in 8 months should be in and of itself a strong argument for the server admins. In my current position, I code and am responsible for a few different servers. It's certainly a strong argument in my eyes. I'm also kind of surprised that with the amount of time that PHP5 has now been out that this is still a question for some people. (not directed at you but maybe the server admins) Once again, pretty strong argument is, if support for PHP4 is being dropped. that must mean that there is much confidence that PHP5 is mature enough... to be the only supported version in being rolled out in production environments.

Re: [PHP] Design Dilemma - Database Data Abstraction
At 4/7/2007 09:49 AM, Martin Alterisio wrote: The solution I presented is to access, and act upon, a database as if they were PHP arrays, meaning that a table is presented as an array of records. This implies to me that you'll read a series of tables into arrays, modify the arrays, then update or recreate the database tables from the arrays. I can't really see how this can work for multiple users because as soon as a second user reads and starts modifying the data there will be obvious discontinuities between the two data snapshots, and updating the tables from one user will erradicate changes made by others. Is this a single-user application you're working on? I could index by the order as they are presented by the DB: $DB['users'][0] is the first user from the query "SELECT * FROM users" $DB['users'][1] is the second user from the query "SELECT * FROM users" etc.. But this have many cons. First, without a deterministic order, the array can change its logic order on the whim of the DB, nobody assures that the order will be kept after a modification is made to the data, and this can be confusing and error prone: $name1 = $DB['users'][3]['name']; $name2 = $DB['users'][5]['name']; $DB['users'][3]['name'] = $name2; $DB['users'][5]['name'] = $name1; The last sentence may not be writing to the adequate record. Hmm. I don't see why this wouldn't work -- you're not changing the keys (3 & 5) required to point to those unique records. I can see a problem if $name1 and $name2 were themselves the keys, but you're not doing that in this example. If that were the problem, though, you could simply mandate a rule that you can never change the key of an array element that represents a data record, so that the record sequence remains what it was originally. However, making your program logic depend on the record sequence as it was read from the database seems quite iffy anyway [especially in a multi-user system]; I'd just use the data table's primary key as the array key and leave it at that. Random access rocks! From what you write, it almost seems as though you're assuming that these statements: $DB['users'][3]['name'] = $name2; $DB['users'][5]['name'] = $name1; actually modify the database records they represent. If so, what system are you using? I just don't see this happening using simple PHP and MySQL. When you read a data record into a PHP array [with, for example, mysql_fetch_array()] that array is just a static copy of the data and doesn't possess any dynamic updating power over the database. Or are you using an I/O class that you're not showing in your example code that executes a modifying query each time an "array element" is changed? Another possible indexation could be by the value of the PK, but this also have some problems. First, it can be confusing if the PK is an autonumeric int, as this might be seen as a numeric indexation. You can prefix an autonumber field with alphabetic characters to force it away from numeric indexing: $sKey = str_pad($aDataRecord['recno'], $iPadLength, 'pk_00', STR_PAD_LEFT); $aArray[$sKey] = $aDataRecord; e.g., recno 12345 becomes array key 'pk_012345' Using str_pad(...LEFT) ensures that the array keys will be in the same sequence as the data records even though the autonumber values will be composed of differing numbers of digits. You just have to choose a pad length that equals the longest series of digits your database will generate for an autonumber field. Second, not all tables have only one field as PK (I can ask that all tables have at least a PK, but I can't ask that the PK is made of only one field). You can construct a single array key from multiple database fields: $aArray['pk_' . $aDataRecord['fieldA'] . '_' . $aDataRecord['fieldB']] = $aDataRecord; unset($DB['users'][$userid]); // delete Unsetting the array element, rather than retaining it with a deletion marker, implies that you're intending to recreate the database tables rather than update them atomically.
