This will never work. Your last array will always overwrite your previous
array.
Here is how I would suggest building it:
$items = array(
1 = array(
serviceid = 1,
servicename= signature required,
price = $4.95
),
15 = array(
serviceid = 15,
servicename = return receipt,
price = $2.30
)
)
This will ensure that your first level indexes never overwrite themselves.
But, with that change made, then do this:
foreach ( $items AS $item ) {
if ( array_key_exists('price', $item) ) {
echo $item['price'];
} else {
echo 'Item does not have a price set';
}
}

Yes? No? Nope. In fact, it's officially supported syntax: http://us3.php.net/manual/en/function.array.php I love it, particularly when used with the already-noted multi-line array syntax (I don't recommend it with single-line arrangements): $foo = array( 1, 2, 3, ); //$foo This makes it dead easy to add, remove, or reorder elements without worrying about accidentally breaking the syntax.

That's because it's not an array you've got the trailing delimiter on,
it's a string. We were talking about commas on the end of the last
element in the array, like:
$var = array(
'foo',
'bar',
);
That only contains two elements, and won't have a hidden 3rd at any
time.

{
echo 'rows=7 cols=30 ';
echo 'value=';
if ($field['null'] == 'YES') // CAN BE NULL?

}
because to create a textarea, the HTML is textarea rows=7 cols=30default
text/textarea. It looks like your code is trying to make a textarea that
starts with input type=' which won't work. See

Hello,
I'm making a menu script that uses mysql, php and javascript to build a on
mouse over dropdown menu to a page. I ran into some problems and would need
help to get this working. (This is just the top level of the menusystem)
1. Get the toplevel links from DB, create array and put values there.
$sql =SELECT * FROM x_menu WHERE menulevel = '1' ORDER BY 'id' ASC;
Yeesh... should be using parent ID references. How does a sub-menu item
know to which menu item it belongs? It has a parent right? What
determines a root menu entry? No parent (or root node parent)... What
is this wierd menulevel field?
$result=mysql_query($sql);
$num = mysql_num_rows($result);
$cur = 1;
while ($num = $cur) {
$row = mysql_fetch_array($result);
$id = $row[id];
$menulevel = $row[menulevel];
$linktext = $row[linktext];
$linkurl = $row[linkurl];
$toplevel =array($id, $menulevel, $linktext, $linkurl);
$cur ++;
}
The first problem comes here. How can I create a different array at every
iteration of the loop? Or how this should be done if the toplevel objects
are echoed with foreach to the browser like this:
Just create the array at each iteration of the loop...
$foo = array( /* put some data in it */ )
$TopLevelCounter = 1;
foreach ($toplevel as $value){
print menuSyS.addItem('labelItem', '$toplevel[2]', $TopLevelCounter,
$width, '$colour1', '#aa', '$colour2');\n;
$TopLevelCounter ++;
}
Now, because I just fill the same array again and again in the DB query all
top level items finally contain the same text. So my question is how to
query the DB and create the arrays so that it would be easy to refer to the
data in the arrays when printing to screen. Do I have to make
multidimensional arrays?
Yes.
If so how to implement them here and how they
should be referred to when printing to browser?
Use a foreach loop for the menu array. When you come across a menu item
with children, use another foreach loop. Alternatively you can use
recursion.
Cheers,
Rob.

Re: [PHP] arrays question
Here's a few loops that should work. You can actually just use the
first loop to concatenate text string instead create array items, but
I wasn't sure what type of processing you wanted to do with the result.
//Convert Array from 3 rows by 2 cols - 2 rows by 3 cols
for($i=0; $icount($mainArray); $i++ ) {
for ( $x=0; $xcount($mainArray[$i]); $x++ ) {
$resultArray[$x][]= $mainArray[$i][$x];
}
}
Resulting Array
Array
(
[0] = Array
(
[0] = 1
[1] = 492
[2] = 11
)
[1] = Array
(
[0] = 2
[1] = 211
[2] = 20
)
)
//Convert array items to text string with , separator
for($i=0; $icount($resultArray); $i++) {
$resultArray[$i]= ''.implode(',',$resultArray[$i]).'';
}
Resulting Array:

[0] = 1,492,11

Re: [PHP] Arrays
Hello,
You may try unset($product) in your loop if you want to delete this var.
Your code $product=array(); must work too...
Another way, must be to use something like this $product[id]=$product_id;
But i dont think it's your real goal?!
Could you give some more information about that?

First of all, where does $product_id come from? You gave us no code
that gives us that.
Second, if you're trying to make an array populated with a feild from
each row returned, your first example will work, but not the second.
The second example will empty the array, and start a new one (which
doesn't make sense to me why you would do that--because in the end,
you're only going to have the array with the last row returned).
But if you're trying to destroy an array doing either:
unset($an_array)
or $an_array = array();
will do the job.

RE: [PHP] Arrays
I guess your purpose is to just save the row data from the mysql to the
array each unit. So may be the result that you expected is sth like:
$product[0] = 1;
$product[1] = 2;
$product[2] = 3;
..
If you just loop for each new value in the loop and to destroy the array,
you second example is okey.

Re: [PHP] Arrays
You can absolutely use arrays as form field names. They allow great
flexibility. Although you wouldn't use quotes for the array keys.
So your form field name would be something like:
att[keyname]
While in PHP, the same array would look like:
$att['keyname']
Your array id's are consider keys since they are not sequential. Just
treat them as names for the array entry. There are a number of ways to
reference it.
$att = $_POST['att'];
foreach($att as $attkey=$attval) {
echo $att[$attkey];
echo $attval;
}
Or you could use the array_keys functions to get the keys to the array
in it's own array that can be referenced sequentially.
$att = $_POST['att'];
$attkeys = array_keys($att);
echo $att[$attkeys[0]];
echo $att[$attkeys[1]];
etc.
You can even use multidimensional arrays as form field names, which is
helpful when you need to keep separate form fields related. Like having
multiple phone number/phone description fields:
input type=text name=phone[home][desc] value=Vacation Home
size=10
input type=text name=phone[home][number] value=123456789
size=10
input type=text name=phone[work][desc] value=Uptown Office
size=10
input type=text name=phone[work][number] value=123456789
size=10
On Dec 28, 2004, at 10:52 PM, GH wrote:
Would it be possible in a form fields name to make it an array?
This way it would be i.e. att[$part_id]
Now is there a way to iterate through the array when I submit the form
to process it, being that the ID numbers are not going to be
sequential and that there will be some numbers not included?
I.E. the id's would be 1, 5, 6, 7, 20, 43
and how would I refence it? would it be $_POST['att']['[partIDhere}'] ?
Thanks

Re: [PHP] Arrays
There are a couple of ways to pass arrays (and their values) between pages. I personally would put the array into a session variable ($_SESSION - see reference) and access the various parts as needed. Another option is sending the whole array or it's parts as hidden fields in a form (access with the $_GET and $_POST - again see reference), but that means the user has to click a submit button. If you are trying to store the array in a Database I would suggest you make each element of the array into it's own column of the database. Databases generally should only have 1 piece of information being saved per cell (think excel). If you would like a link to database design, let me know and I will send it.

Re: [PHP] arrays and sessions
I've got some code and it simply isn't working. I thought it might be because each time the form submits data, the array I'm storing information in is being re-initialized. If this is the case, I don't have the multidimensional array I'm trying to get, but just a vector array with the most recent submission data. I tried making the array a session variable, but I'm not even sure the session part of it is working. So, if you have any methods that you think might work better than what I'm trying to do, I'd love to hear about it. Basically, my file is structured like this: 1. Pull in POST data, and store them in php variables 2. If the POST data is null, display the first form and get the table name, field name, field type, primary key, and null allowed information. On submit, the information is stored in an array. 3. If the POST data is not null, again display the entry form in case the user needs to add more fields, and step through the array to display the existing table info that the user has already entered. A button in a second form is also displayed. When clicked, it actually creates the table. My problems are that when I try to step through the array and display its current contents, I get index not defined errors on my for loop indices (?!). The second problem is, when I try to use the print_r function to display my array, it only displays one set of data. This might be because I'm trying to do a C++ type 2 dimensional array concept when PHP arrays are associative by nature, and I'm not sure how to get around this. Suggestions? (Yes, Kermit is my real name. Miss Piggy is well, and sends her regards.) -Kermit Chris W.

Re: [PHP] arrays and sessions
First of all, make sure you're doing session_start() before
reading/writing any session data and before you do any output.
Second, You likely need to just do something like this:
session_start();
if(post data) {
$_SESSION['formArray'][] = $_POST;
}
This will save each POST array as-is in the session.

?php
$iteration = ++$_POST['iteration'];
$_SESSION['post_data'][$iteration] = $_POST;

echo QQQ
form method=post action=myself

input type=hidden name=iteration value=$iteration /

?
you should then see a multi-dimensional array with
'print_r($_SESSION);'.
this code is untested and not very complete. ;) but maybe it will give

Re: [PHP] Arrays and performance
Hi, I belive PHP should be able to handle it but it's a bad idea. The reason being your app will not scale. Because if you script consumes 2mb of memory on average, 100 users accesing it at the same time will be 200Mb. Of course if you expect only a small number of users it does not matter. The biggest XML job i have handled with PHP is parsing the ODP RDF dump which is around 700MB. Obviously arrays are out of the question in such a scenario, even though only one user will be accessing the script at a given moment. the ODP dump has a couple of million records Kim Steinhaug wrote: Something Ive wondered about as I started working with XML. Importing huge XML files, and converting theese to arrays works indeed very well. But I am wondering if there are any limits to how many arrays the PHP can handle when performance is accounted for. Say I create an array from a XML with lots of childs, say we are talking of upto 10 childs, which would give 10 dimensional arrays. Say we then have 10.000 records, or even 100.000 records. Will this be a problem for PHP to handle, or should I break such a prosess into lesser workloads (meaning lesser depth in the array)?

Re: [PHP] Arrays and performance
hi, In fact i had to handle the ODP dump on two occaisions the first time the results went into a mysql db, the second time it went into a series of files. On both occaisions i used SAX parsers. DOM would just roll over and die with this much of data. I placed code in the end element handler that would either save the data into a db or would save it to a file. In either case i only kept the data in memory for a short period. ie from the time the start element was detected through the character data handling until the end element was detected. (Obviously i am not talking of the root node here :-)) During the whole process you barely noticed the memory usage, however the disk usage still went up of course. Reading from disk 1 and writing to disk 2 does wonders! please let me know if you need any further clarifications.

Re: [PHP] Arrays and performance
Thanks for your reply! Im going to use this for a backup system for our webstore system, where some of our customers have *alot* of products. Given the structure of the database with categories and images 5000 unique products quickly gives 3x = 15000 arrays. But again, how often would the client need to revert the backup? Ive never needed to do it for now, but I still want to do this backup system in XML (Looks kinda up to date, :), and at the same time know that it will eventually work - even for the customers that infact has alot of products in their system. The alternative, would be that customers with x products would only have access to mySQL dump. Or to have a script that evaluates the XML file and prompts the user that this file is to large for automatic import / revert. a) From what I understand of your answer you're telling me that PHP itself will not have any problems working with 1.000.000.000 arrays, aslong as there are enough ram and processing power available, and that the timeout is extended. Or would the PHP die a painfull death as soon as it gets to much data? Could we coclude the follwing, XMLfile 200 MB = No PHP! b) I should do some benchmarking, to find the magic marker for how much XML data that is affordable to grab when done on a webserver with other clients to prevent angry customers or failures due to factory timeout setting to 30 secs. -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- Raditha Dissanayake [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, I belive PHP should be able to handle it but it's a bad idea.

faster than using concatenation, but every benchmark I've tried

reach the same conclusion.
I tried this, and I think the comma was just slightly faster than the
period. But then again I didn't always get consistent results because I
was trying this out on a machine that is not very fast so the speed at
which is processes something varies quite a bit.
My conclusion was that it's not fast enough to bother changing all my
code, or start writing in a new way.
Although during some testing I did find that writing loops in the
following way is faster than normal.
$counter = -1;
while(++$counter $amount)
{
// do stuff
}
It made a big enough difference on my slow machine to merit me writing
as many loops in this way as I can. (I think.)

How about:

Re: [PHP] Arrays and Alphabetical order
I need it to echo out a table with all the A's first, then a blank line,
then all the B's, a blank line and so on. I could write 26 different
queries, one for each letter of the alphabet, but surely there is a tidier
way.
Do a query, sorting by the field you need alphabetized. Then do this (and
tidy it up as you need):
echo table;
while($result = mysql_fetch_row$(query)) {
if(substr($result, 0, 1) != $previousfirstletter) {
$previousfirstletter = substr($result, 0, 1);
echo trth$previousfirstletter/th/tr;
}
echo trtd$result/td/tr;
}
echo /table;
It's untested, but I believe it will work.

Re: [PHP] Arrays and MySQL
It gets a little more complicated than this. There are several teams (each
with 20 players) and then there is the team owner and then there is the
player position, etc. So to do this I would have to do some kind of a join
and so on - and to date haven't been able to figure this out with sums. I
would also have to do a second query (I am already doing one to get the
points for each player), so I might as well just use it and through the
results in an array and then total it from there - and thus my question of
how I total the array

You can use array_sum().

You can use array_sum().
What about SELECT SUM(Goals), SUM(assists)?

Re: [PHP] Arrays and MySQL
You can use array_sum().
I have used that in the past, but only on single arrays, I can't figure out
how to do on multi-level arrays, and since I need to have different totals
from different levels of the array, I don't think this will work. If you can
shed some light on this it would be appreciated.
From below - $totals[0][4] through $totals[19][4] , $totals[0][5] through
$totals[19][5], etc.

Re: [PHP] Arrays of strings from regex
David Pratt wrote:
Am working through document to collect pieces that match and then insert
them into an array so they can be used to construct another file.
Looking in my doc for lines like this:
{\*\cs43 \additive \sbasedon10 db_edition;}

{\*\cs45 \additive \sbasedon10 db_email;}
Wrote this regex to find them:
^\{\\\*\\?(cs[0-9]{1,3}) (.*)\\[a-z0-9]+ (.*);\}$
^
I suppose this wants to eat the whole line, use ([^ ]*) - all except space,
or switch to perl expressions with its ungreedy match
Now looking for best method for getting the parts in parenthesis () into an
array so it will contain these values by finding the above three lines:
$matches [0][0][0] = cs43 , \additive \sbasedon10, db_edition
$matches [1][1][1] = cs44 , \additive \sbasedon10, db_editor
$matches [2][2][2] = cs45 , \additive \sbasedon10, db_email
Thanks in advance for any pointers.
