Yes, so maybe a simple preg_replace():
extract(array_combine(preg_replace('/^f_/', 't_', array_keys($_POST)),
array_values($_POST)));
You could also just replace with '' and then use the extract prefix of 't'.

Yeah. But this feature of PHP is a boon if used carefully and a curse if
careless. You can get AMAZING results if you're not careful to check the
data types ;)
And that's why language like C# and java supports to restrict the type
of data a collection can hold.

It's not clear what you are doing, but here is the problem that you are
asking about. array_combine() builds an array using the values from
$from as the keys of the new array and the values from change as the
values of the new array.
So here, if $locations2 is a value in the $from array:
if(in_array($location2, $from)) {
But here you are searching the values of $new_array which are copies of
the values from $to.
$key= array_search($location2,$new_array);

I have a very handy utility for problems like this:
// Expand string array, list all terms
function larec($array, $name) // List array recursive
{
if (is_array($array))
{
$j = count ($array);
$temp = array_keys($array);
$i = 0; while ($i $j)
{
if(isset($array[$temp[$i]]))
{
$new_line = $name.['.$temp[$i].'];
larec ($array[$temp[$i]], $new_line);
}
$i++;
}
}
else
{
echo 'p'.$name.' = '.$array.'/p';
}
}
If you have some array $foo then larec($foo,'Foo'); will list all the elements
of $foo
recursively, without any obvious limits. This makes it very easy to see what
you have
actually got, as opposed to what you thought you would get. The following is
an abridged
example of the result of listing an array $wkg_sys of mine, using:
larec ($wkg_sys,'Sys');
Sys['class'] = W
Sys['style']['0']['wkg_style'] = basic_tab
Sys['style']['0']['pad'] =
Sys['style']['0']['stripe'] = 0
Sys['style']['1']['wkg_style'] = nrml_style
Sys['style']['1']['pad'] = 1
Sys['style']['1']['stripe'] = 0
Sys['valid'] = 1
Sys['entries'] = 15
Sys['f_title'] = Developmental Web Page
Sys['version'] = IF1.4
Sys['ident'] = 0800
Sys['directory_id'] =
Sys['index'] = 2
Sys['date'] = CCY2N

}
That's bad, because it will run a variable number of SQL queries.
It's better to pull all of the data at once, and then recurse over that data
structure. To wit (off the cuff and not tested, using PDO syntax for the
database):
function print_menu() {
$items = array();
$db = db_connection();
$result = $db-query(SELECT menu_id, parent_id, name FROM menu_items ORDER
BY name);
foreach ($result as $record) {
$items[$record-parent_id][$record-menu_id] = $record;
}
$output = _print_menu($items, 0);
return $output;
}
function _print_menu($items, $parent_id) {
$output = '';
if (!empty($items[$parent_id])) {
foreach ($items[$parent_id] as $menu_id = $item) {
$output .= 'li' . $item-name . _menu_print($items,
$menu_id) . '/li';
}
}
return $output ? ul$output/ul : '';
}
That way you run only one SQL query, and by pre-grouping you can reduce your
iterations as well.

$resultArray will contain the output you specified; pretty quick IMO.

[PHP] Re: Array Question
Well I don't want have to specify $val['ponbr'] == 'TEST1' I want to say if
($val['ponbr'] == repeated value) then $resultArray[$key] = $val;
In other words I want to go through the array matched the values of ponbr
that repeat or are the same so if they match then I put the results in
another array. Does this make sense? sorry I have difficulties with arrays
still.
thnx for your input

RE: [PHP] Re: array variables with or without quotes
I believe it is because without the quotes, it is expecting a predefined
constant. With the quotes, it is expecting an array key. This is why if you
use a word that is not defined as a constant, php will first look for it as
a constant, won't find it, then looks through the array treating it like a
key. If it is found as a constant, then the constant's value is used as the
key.

Since foreach sets pointers and reads only array fields and not the whole array. Your example would pump the whole array in one var.

It would be interesting to know whether that method was faster or
slower than using this:
$iLen = strlen(implode(, $aArray));
the problem I would have with the above code would be that it assumes
you're using a single dimention array.
Recursive foreach:
function array_size($a){
$size = 0;
while(list($k, $v) = each($a)){
$size += is_array($v) ? array_size($v) : strlen($v);
}
return $size;
}
This could possibly be optimised even more by using references or something
like that.
eg
foreach(array_keys($a) as $k){
size = is_array($a[$k]) = array_size($a[$k]) : strlen($a[$k])
But I think that for the most part your time programming will be more
important than the programs time running.

Do something like:
$checkboxes = array('food','drink','smoking');
// display the checkboxes
foreach($checkboxes as $checkbox) {
echo $checkbox: input type=checkbox name=\$checkbox\ /;
}
Then when processing the form input check if each of the $checkboxes
array values are present, if not, you can set to something else such as
N, like so.
$sent_data = array();
foreach($checkboxes as $checkbox) {
if(isset($_REQUEST[$checkbox])) {
$sent_data[$checkbox] = 'Y';
} else {
$sent_data[$checkbox] = 'N';
}

your vehicle name displayed? If it is, and you're using it correctly, make
sure you're returning the value you'd like correctly. It might help to post
your grabQuotes function as well as the code that displays $cars[].

Hello all,
I have some array code driving me nuts.
I am pulling from a db:
select id, vehicle, has_quotes from cars where active=1
I then loop through these and build an array that contains the id's and
cars.
while($res){
$cars[$res[id]]=$res[vehicle];
//here is the problem, when has_quotes is 1, I call another function
to grab the quotes
if ($res[has_quotes]1){
$cars[$res[id]]=grabQuotes($res[id]);
}
}
The grabQuotes function returns an array and works fine. THe problem
is when I go to display these, I cycle through the car array printing
id and vehicle name. I do a check so if vehicle name is an array, I
print out the quotes from the inner array, problem is I have lost the
vehicle name! How can I fix this?

[PHP] Re: array from folder
* Ed Dorsch [EMAIL PROTECTED]:
Can PHP generate an array based on file names in a folder?
For example, if I have a folder called photos that includes three
files -- tree.jpg, house.jpg and boat.jpg -- can PHP look at the
file and generate a variable $photos = array (tree,
house,boat). Any ideas for how to sniff out a folder to
determine how many files are in it and then create an array with the
file names in it?
You might want to try PEAR's File_Find package. With it, you could pass
a pattern to match, and receive an array of files that match. You could
then use array_map() to strip the suffix:
include_once 'File/Find.php';
function photo_basename($file)
{
list($name, $sfx) = explode('.', basename($file), 2);
return $name;
}
$photos = File_Find::glob('/.*\.(jpg|png|gif)$/i', 'photos', 'perl');
$photos = array_map('photo_basename', $photos);
To determine the number of files, simply do a count() on the $photos
array.

I might be the only one to notice here, but you don't want to find the
KEY, you want to find the VALUE. Otherwise, you'll need to assemble your
array differently.
$viz_ip= $_SERVER['REMOTE_ADDR'];
$byte_ip= array(
204.126.202.56=Mark,
63.230.76.166=Bob,
63.220.76.165=John
);
That means:
$byte_ip[$viz_ip] = some_name;
That's because you have ips set as your *keys*, and not your values. To
do what you wanted, simply either:
a) reverse the array, making keys values and values keys:
$byte_ip= array(
Mark=204.126.202.56,
Bob=63.230.76.166,
John=63.220.76.165

Maybe it works if you put the expires value in a seperate array, sort it and
then you can get the key of the first one and use unset():
foreach ($foo as $key = $value) {
$tempArray = array();
foreach ($value as $subkey = $subvalue) {
// add expires value only to the temporary array for
sorting
$tempArray[$subkey] = $foo[$key][$subkey]['expires'];
}
// sort array by value descending
arsort($tempArray);
// get first (and therefore highest timestamp) key/value pair
$firstEntry = each($tempArray);
$notneededSubkey = $firstEntry['key'];
// now unset the array value with the not needed subkey
unset($foo[$key][$notneededSubkey]);
}
Have not tried it but may work. Hope you see my point.

I've managed to get the list so that all the (sub) entries are sorted in
the correct order. Now its just a matter of finding the highest expire

foreach ($foo as $key = $value) {

foreach ($value as $subkey = $subvalue) {

By the way, isn't there a way to filter this stuff BEFORE or WHILE the whole

By the way, isn't there a way to filter this stuff BEFORE or WHILE the whole
array is created?
Thanks for the help. I'll give that snippet a try and see what comes out.
The array is a result of a rather nasty SQL statement running against a
database (which I didn't design). Unfortunately, the way the database is
designed, its very difficult to extract the domain information.
I am in the process of rewriting the entire thing as a Java application,
hopefully that will make things a bit clearer, since I'll also be
refactoring the database schema.
Many thanks,

Re: [PHP] Re: Array Sorting Headaches
OK, so it's just the other way round - I see. Instead of deleting the
entry
with the highest expiry date we delete all the others:
foreach ($foo as $key = $value) {
$tempArray = array();
foreach ($value as $subkey = $subvalue) {
// add expires value only to the temporary array for
sorting
$tempArray[$subkey] = $foo[$key][$subkey]['expires'];
}
// sort array by value descending
arsort($tempArray);
/* new stuff starts here */
// remove the entry with the latest expiry (the first array
element)
array_push($tempArray);
// now unset all remaining/not needed entries
foreach ($tempArray as $tempKey = $tempValue) {
unset($foo[$key][$tempKey]);
}
}

[PHP] Re: Array Sorting Headaches
Burhan Khalid [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
Greetings everyone :
Having a hard time with this one. I have a multi-dim array
$foo[$x][$y]['key'], where $x and $y are numeric. Here is some sample data
:
Array
(
[$x] = Array
(
[0] = Array
(
[invoiceid] = 11842
[product] = myproduct
[domain] = foo.net
[expires] = February 28, 2004
)
[1] = Array
(
[invoiceid] = 10295
[product] = myotherproduct
[domain] = foo.net
[expires] = December 9, 2003
)
[2] = Array
(
[invoiceid] = 10202
[product] = product1
[domain] = foo.bar
[expires] = January 19, 2003
)
[3] = Array
(
[invoiceid] = 10005
[product] = product2
[domain] = foo.bar
[expires] = December 11, 2002
)
)
)
I need to filter the results so that I get the latest expiry date for
each product. The expires field actually contains a timestamp. So for
the sample array above, the resultant array would have only keys 0 and
2, filtering out all the rest. There are around 180+ main entries, with
any number of sub entries, but each sub entry has the same four keys.
Any ideas? Getting a rather large headache mulling over this.
Hi,
as your structure is always the same you could just loop through all
elements and subelements and use unset() to remove the unwanted array
elements:
foreach ($foo as $key = $value) {
foreach ($value as $subkey = $subvalue) {
// put your check logic here
if ($foo[$key][$subkey]['expires'] == '') {
unset($foo[$key][$subkey]);
}
}
}
What do you think?
Regards, Torsten Roehr
Thanks again,
Burhan

I'm afraid you'll have to start learning PHP from scratch. The freely-available PHP
manual has a fairly good introductory section and you'll also find tons of tutorials
for
beginners on the web.
Good luck,

RE: [PHP] Re: array block
If you have an array like this (change the url to href):
$menu = array (
'link1' = array(
'url' = 'foo',
'title' = 'bar'
'style' = 'dolor'
),
'link2' = array(
'url' = 'foo',
'title' = 'bar'
'style' = 'amet'
)
);
Then something like this, or the general idea should work:
$menu = array (
'link1' = array(
'href' = 'foo',
'title' = 'bar',
'style' = 'dolor'
),
'link2' = array(
'href' = 'foo',
'title' = 'bar',
'style' = 'amet'
)
);
foreach ($menu as $array) {
$tag = a;
foreach ($array as $k = $v) {
$tag .= $k=\$v\;
}
$tag .= $menu/a\n;
echo $tag;
}
There are better ways to do it I'm sure, but this is just following the
previous example.

Since it's two-dimensional, the $v you're getting is actually an array.
So you'll have to iterate through the outer array, $menu, and then do
it again for each inner array.
As was mentioned before/elsewhere, a for would be more efficient than a
foreach unless you actually need a specific key or value. So something like
$count = sizeof($menu);
for ( i=0; i$count; i++)
{
foreach( array_shift($menu) as $k = $v )
{ //ect. }
}
It's been a long day; please, someone verify this... :)

The way I would do what you are trying to achieve is go the $_SUPERGLOBALS
way..
on the submit_information.php page:
?php
session_start();
$_SESSION['image'] = $_POST['image'];
foreach($_SESSION['image'] as $foo){
echo $foo . br\n;
}
?
Also, another good way of debugging etc is to use the print_r() function
(http://www.php.net/print_r)
If you do :
pre?php print_r($_SESSION);?/pre
This produces a nice formatted look at the the session arrays/structures -
same goes for all arrays.
Hope that helps,

[PHP] Re: Array Searching
i have an array like:
Array
(
[1] = Array
(
[alias] = foo
...
)
[2] = Array
(
[alias] = bar
...
)
...
)
I need some way to find out, if an alias foo is in the array. Any idea how
to do this?
Assuming your outer array is called $array_of_arrays:
?php
$found = 0;
foreach ($array_of_arrays as $array) {
if ($array['alias'] == 'foo') {
$found = 1;
break;
}
}
if ($found) {
// you found it!
}
else {
// too bad!
}
?
Or, you can look at this:
http://www.php.net/manual/en/function.in-array.php
if you're not sure what key 'foo' will be at, or this:
http://www.php.net/manual/en/function.array-search.php
if you're not sure what key 'foo' will be at and you want to know what
that key is.

[PHP] Re: Array Javascript
if you have an array in javascript:
array1 = [1,2,3,4,5,6,7,8,'test'];
etc...
you can join it in JavaScript to make it a one string as:
array1 = array1.join('|');
then split in PHP to make it back an array:
?
$array1 = explode('|', $array1);
?
good luck,

can do this:

Don't use this method though! It makes your program slow!

This may be a silly question, but I'm used to being able to find PHP
functions to do whatever I want, but I can't find one to do this!
If I have an array like this:
[0] - 'apple';
[1] - 'pear';
[2] - 'orange';
[3] - 'apricot';
I know I can use in_array() to check whether, say, 'orange' is in the
array; but how do I then find out which index 'orange' is at?

RE: [PHP] Re: ARRAY, IF INSERT
Thanks for the input. I wasn't considering the possibility of making a new table for kids until now which seems pretty logic when trying to save space. The only thing missing now is how to assign a unique relation number for each kid/relative. That's 1 for the first born, 2 for the second one, etc... and it can't be done by auto_incrementing, for it will start over when a new member is inserted... i.e. the relatives table should show: Member level nameaddress 00251 Jr.1same as 0025/0 00252 Jr.2same as 0025/0 00261 Jr.1same as 0026/0 00262 Jr.2same as 0026/0 00263 Jr.3same as 0026/0 The catch would be to make PHP to auto assign the relatives level by knowing it has to start from $i=1 and loop $i++ until no other kid is inserted. Now that I write it, it seems I could use a for loop, but what should be the structure of it using the $name 0 you told me?
