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';
}
}

[PHP] Arrays: Comma at end?
Was there ever a time when having a comma at the end of the last array element was not acceptable in PHP? I just did a few quick tests: https://gist.github.com/1761490 ... and it looks like having that comma ain't no big deal. I can't believe that I always thought that having the trailing comma was a no-no in PHP (maybe I picked that up from my C++ classes in college? I just don't remember where I picked up this (bad) habit). I would prefer to have the trailing comma... I just can't believe I have avoided using it for all these years. Thanks!

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.

[PHP] Arrays Regexp - Help Requested
Happy New Year, here's my first question of the year (and it's only 15 hours
into the year!).
I am creating a small database management tool for my a website (my work IP
blocks my access to PhpMyAdmin) and I don't want to install any additional
software.
I am working on adding rows and need to format the input boxes properly (ie.
VARCHAR needs an text input, TEXT needs a textarea input). Using a mysql
query I can determine the data types for each field. I have a function that
uses this information to return datatype specific variables. For example
$field['field'] may equal int(6) or varchar(256).
The code is a bit extensive, but it's necessary to explain what's going on.
?php
// Loop:
echo 'table width=100% cellspacing=1 cellpadding=2 border=0' .
\n;
foreach ($fields as $field)
{
// ROW BEGIN
echo \t . 'tr' . \n;
// NAME OF FIELD
echo \t\t . 'td`' . $field['field'] . '`: /td' . \n;
// FIELD DATA TYPE
echo \t\t . 'td' . $field['type'] . '/td' . \n;
// VALUE INPUT
echo \t\t . 'td';
$input_type = printByType($field['type'], 'INPUT_TYPE');
echo 'input type=' . $input_type . ' ';
if ($input_type == 'text')
{
echo 'size=';
$length = printByType($field['type'], 'INPUT_LENGTH');
echo $length;
echo ' ';
echo 'value=';
if ($field['null'] == 'YES') // CAN BE NULL?
{
echo 'NULL';
}
echo ' ';
}
elseif ($input_type == 'textarea')
{
echo 'rows=7 cols=30 ';
echo 'value=';
if ($field['null'] == 'YES') // CAN BE NULL?
{
echo 'NULL';
}
echo ' ';
}
echo 'name=value[] id=value[]
onfocus=if(this.value==\'NULL\')this.value=\'\'; /';
echo '/td' . \n;
echo \t . '/tr' . \n;
}
echo '/table';
?
The function:
?php
function printByType($string, $mode)
{
(string) $string;
$lengths = array(
'VARCHAR' = 10
, 'TINYINT' = 1
, 'TEXT' = 10

switch ($mode)
{

foreach ($lengths as $key = $val)
{
(string) $key;

// DETERMINE LENGTH VALUE eg. int(6) GETS 6

switch ($length_value)
{

return $length_value;
break;
case ($length_value 7 $length_value 15):
return $val += ($length_value/2);
break;
case ($length_value 14 $length_value 101):
$result = ($length_value / 5);
$divide = ceil($result);
return $val += $divide;
break;
case ($length_value 100):
return 40;
break;
default:
return 7;
break;
}
return $val;
}
else
{
return 7; // default value
}
}
break;
case 'INPUT_TYPE':
foreach ($types as $key = $val)
{
(string) $val;

$found = preg_match($regex, $string);
if ($found === false)
{
return 'text'; // default value
}
else
{
return $val;
}
}
break;
}
}
?
The first part of the function (the first switch case) works, and the text
fields are variable in length, but even the fields with a TEXT datatype is
printing out a text box instead of a textarea. Can anyone see why this is
happening?
Thanks!
Re: [PHP] Arrays Regexp - Help Requested
I think the problem is here:
echo 'input type=' . $input_type . ' ';
[...snip...]
elseif ($input_type == 'textarea')
{
echo 'rows=7 cols=30 ';
echo 'value=';
if ($field['null'] == 'YES') // CAN BE NULL?
{
echo 'NULL';
}
echo ' ';
}
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
http://www.w3.org/TR/html401/interact/forms.html#h-17.7 for how to use textarea.

The data is actually stored as a text document, with a separate line for each piece of information. To minimise the file length blank fields are simply omitted. When I load the file into memory it is much simpler to enter only the fields which are actually specified. As there are ~600 entries this presumably gives a significant saving in loading time and in memory. However if I take this approach I then have to add an if(isset( ...)) test before I read each field when I'm trying to access a specific entry. This would only increase the memory usage by a very small amount, and would have a negligible effect on timing. So if I fill in all the entries when I load the file it will increase the loading times slightly, and use slightly more memory. On the other hand it will save me from having to think about it whenever I access a variable. The question really comes down to whether the saving in memory if I don't load the empty variables is worth the extra programming hassle when I write new procedures for accessing an entry. so one would guess that code would far outweigh any tiny speed gain from dropping the additional items in the array. on another note; php has been stable and speedy now for a very long time, some bit's like the reflection api could be speeded up a little bit as demand grows, but certainly all scalars and compound types have been tested and optimized to hell and back (afaik). One could reasonably hope that the same could be said for every part of the programming chain, but it is one of the ironies of modern computing that computers get faster and faster, memory gets cheaper and cheaper, programming appears to get simpler and simpler, yet the programs get slower and slower. I have a fairly modern (maybe 2yo) computer, and use XP professional 5.1. Not long ago I switched to Office 2007 12.0, and when I did so I was appalled to discover that if I had a document loaded into Word, and hit Ctrl A, I could watch the highlighting scroll down the screen!

[PHP] Hidden costs of PHP arrays?
PHP arrays permit extremely concise programming; for example if I have all my contacts in an array $contacts, I can write: $my_phone_no = $contacts['clancy']['phone']; However it is clear that there must be a lot going on behind the scenes to achieve this simple result, as it requires some sort of search procedure. Is it possible to give any indication of the overheads and memory costs that are involved in such a statement, and of how well the search procedure is implemented? Also what the relative virtues of defining the same set of fields for every contact, as against either defining only the fields which actually hold values, as in the following examples? a: $contacts['clancy']['home_address'] = 'jkjkjk'; $contacts['clancy']['home_phone'] = 0123 4567; $contacts['clancy'][' office_address''] = ''; $contacts['clancy']['office_phone'] = ''; $contacts['joe']['home_address'] = ''; $contacts['joe']['home_phone'] = ''; $contacts['joe']['office_address'] = 'jsfvkl'; $contacts['joe']['office_phone'] = 'jsfvkl'; b; $contacts['clancy']['home_phone'] = 0123 4567; $contacts['clancy']['home_address'] = 'jkjkjk'; $contacts['joe']['office_address'] = 'jsfvkl'; $contacts['joe']['office_phone'] = 'jsfvkl'; And is there any advantage in always assigning the keys in the same order? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Arrays help
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;
$result=mysql_query($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:
$TopLevelCounter = 1;
foreach ($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? If so how to implement them here and how they
should be referred to when printing to browser?
Thanks

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.

It is a rather simple re2c parser. Don't look at var_unserializer.c, look at var_unserializer.re and read up on re2c. http://re2c.org/ You would obviously want to replace the creation of internal PHP data types with whatever you want to unserialize to in your app, but I don't see how you would find any code somewhere else where you wouldn't need to yank out the destination code from since that is going to be the unique part in each implementation. And if you use the same re2c grammar that PHP uses, it will be correct. Using any other implementation likely wouldn't be. Of course, I also wouldn't suggest using serialized PHP for a target that wasn't PHP. Why don't you look at json or perhaps wddx instead? -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

return $ret;
then...

if you want to make it associate you can...just push the assocative onto
another array so you get the complete set...

[PHP] Question for PHP Arrays
Hi,
I'm making a PHP Installer that is customizable by using plugins, I haven't
used PHP for a while and which I have forgotten some things about PHP *eek*..
Anyway, I want to know how to add things to an array. Like this:
$foobar = array()
$foobar['rar']['miaw']
Would that output come out (for the array) as:
array(
'rar' = 'miaw'
)
Please correct me if wrong. Also I need to ask one more question, would this
work:
$foobar = array()
function addToArray($int, $value) {
$foobar[$int][$value]
}
And with a function call addToArray(1, meow) output as the array looking
like:
array(
'1' = 'meow'
)

No, it would create a multi-dimensional array that contains nothing.
You want:
$foobar['rar'] = 'miaw';
Please correct me if wrong. Also I need to ask one more question,
would this

$foobar = array()

No (because of the mistake commented on above). However another issue
at play here is scope. $foobar the array will not be visible to the
function addToArray unless you make it global.

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:
Array
(
[0] = 1,492,11
[1] = 2,211,20
)

[PHP] Arrays
Hi,
How can i destroy an array?
I mean i have a loop and for each new value in the loop i want to destroy the
array. Something like that:
while($row = mysql_fetch_array($result))
{
$product[] = $product_id;
// some code here
}
I've tried this but doesn't work
while($row = mysql_fetch_array($result))
{
$product = array();
$product[] = $product_id;
// some code here
}
Any help would be appreciated !!
Re: [PHP] Arrays
Hello,
You may try unset($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

Would it be possible in a form fields name to make it an array?

Now is there a way to iterate through the array when I submit the form

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}'] ?

on that line, what is the error you are trying to catch? I can't read what
ever language that is ;-) thanks.

/snip
You need to generate the javascript array from your PHP array.
Example:
In your script create a php array of the values you wish to use. Using
indeces is not essential. If you do not use them, you can just use a
counter var when you loop through the array to create the indeces for
the JS array.
?php
$arrayVar = array('first index'='item 1', 'second index'='item 2',
'third index'='item 3');
$jsVar = var myArray = new Array();\n;
foreach ($arrayVar as $idx=$val) {
$jsVar .= myArray['{$idx}'] = {$val}\n;
}
?
The final output of this will be:
var myArray = new Array();
myArray['first index'] = 'item 1';
myArray['second index'] = 'item 2';
myArray['third index'] = 'item 3';

RE: [PHP] Arrays
Hi Ben, Welcome to the wonderful world of PHP. Working with array in PHP is very easy. A large number of functions are there. Please visit the manual http://www.phpcertification.com/manual.php/ref.array.html You can move values ( including Arrays) from page to page in session variables. But you need to do serialize and unserialize in case of array or object. Do :: $val_ar=array(one,two,three); $_SESSION['val_ar_store']=serialize($val_ar); Now you can get your array in any page simply $val_ar=unserialize($_SESSION['val_ar_store']); Print_r($val_ar); This process is very simple. Please see manual http://www.phpcertification.com/manual.php/function.serialize.html http://www.phpcertification.com/manual.php/function.unserialize.html Revert back with any other problem.

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. If all you really were asking was how to iterate through an array - then I would recommend looking at the manual's page on arrays ( http://www.php.net/manual/en/language.types.array.php ).

[PHP] arrays() current() next() who to use

do {
//SET ARRAYS
$z['username'][$k] = $row_rsUSERIDID['uname'];
$z['distance'][$k++] = $totaldist;
} while ($row_rsUSERIDID = mysql_fetch_assoc($rsUSERIDID));

//SORT BY DISTANCES
natsort ($z['distance']);
reset ($z['distance']);
foreach($z['distance'] as $k = $v){
$newuser = {$z['user'][$k]};
echo $newuser . br;
}
How can I now get this output displyed in groups of 10 so that I can display
them 10 at a time on a page then click a next button to dispaly they next 10
and so forth?

Re: [PHP] arrays() current() next() who to use
Problem with that is it sorts according the results of the recordset range. For instance: It will show the user 1 trhough 10 sorted by miles then 20 - 30 sorted by miles, however, in 1 through 10 could have a range of 0 to 1000 miles and the next set will have 5 to 200 miles. What I need is to sort them all by miles first. The only way I know to do that is to do the way I set it up. So if I create an array, sort that array by the miles then use that array. However the array is different that the recordset and thus does not use LIMIT. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

First I create a do..while loop to get the miles
do {
$k = 0;
//SET FIRST ARRAY OF ONLINE USERS AND CALCULATE MILES
do {
//GEOZIP
$zip2 = $row_rsUSERIDID['zip'];
$coor1=mycoors($zip1);
$coor2=mycoors($zip2);
$line1=split(\|,$coor1);
$line2=split(\|,$coor2);
$totaldist=distance($line1[0],$line1[1],$line2[0],$line2[1],mi);
//SET NEW ARRAY WITH MILES
$z['username'][$k] = $row_rsUSERIDID['uname'];
$z['distance'][$k++] = $totaldist;
} while ($row_rsUSERIDID = mysql_fetch_assoc($rsUSERIDID));
//SET NEW ARRAY
$z['user'] = $z['username'];
//SORT BY DISTANCES
natsort ($z['distance']);
reset ($z['distance']);
//DISPLAY USER INFORMATION SORTED BY MILES

$newuser = $z['user'][$k];
echo $newuser . - . $v . br;
