Assunto: [PHP] Array help.
I am processing v4IP's and what I want to do is a prefix substitution if the
3rd octet matches a predefined list $groupMappings. I went down this path
and it isn't working as expected. Drawing a blank on this one. Why does 40
miss the comparison?
$hostname = Z;
$ips = array('10.1.40.1','10.1.41.1','10.1.1.1','10.1.40.1','10.9.1.1');
foreach ($ips as $ip) {
$groupMappings = array('40' ='A','41' ='B','1' ='C');
$ocTest = explode(., $ip);
$groupKeys = array_keys($groupMappings);
$groupTest = array_search($ocTest[2], $groupKeys);
if($groupTest != FALSE) {
$hostGroup = $groupMappings[$groupKeys[$groupTest]];
echo Hit! $ip : $hostname : $hostGroup\n;
} else {
$hostGroup = substr($hostname, 0,2);
echo Miss! $ip : $hostname : $hostGroup\n;
}
}
Miss! 10.1.40.1 : Z : Z
Hit! 10.1.41.1 : Z : B
Hit! 10.1.1.1 : Z : C
Miss! 10.1.40.1 : Z : Z
Hit! 10.9.1.1 : Z : C
Thanks!

I think you're making a little bit of a meal of this. My initial thoughts
included pointing you at array_key_exists() (and, why on earth
have you got $ocTest[2] in quotes?), but then I realised if I were
writing this I'd probably just use isset(), thus:
$ocTest = explode(., $ip);
if (isset($groupMappings[$ocTest[2]])):
// success
else:
// fail
endif;
Hope this helps!

Re: [PHP] array
how can you explain someone in a simplest and everyday use example of ARRAY.
The manual page explains it pretty succinctly. I don't think you'll get
more simple than this, as there is obvious prerequisite knowledge
assumed (i.e. that you know what a simple variable is, etc)
Hi saeed,
Ash means this:
http://www.php.net/manual/en/language.types.array.php
See the examples in grey-colored boxes.
Arrays are just a collection of things. Similar to when you assign one
variable one value.. well with an array you assign many variables one value
each. But the reason you use an array is that instead of a bunch of separate
variables, you want those variables to be part of a collection.. i.e. all
those variables have something in common.. like for example you might use one
array to describe the parts of a car, and another array to describe all the
fruits in your kitchen.
You could do this: (all separate independent variables)
$part1 = 'spark plug';
$part2 = 'rear-view mirror';
$part3 = 'steering wheel';
etc.
$fruit1 = 'apple';
$fruit2 = 'banana';
$fruit3 = 'orange';
etc.
...but (depending on your application, and the logic you use), it might make
more sense to do something like this instead: (make arrays!)
(these, below, are arrays where the key is just a number which is automatically
assigned. You can also use another syntax (see the manual) to make arrays
where you generate your own custom keys, and those keys can be strings instead
of numbers.)
$arrParts = array('spark plug', 'rear-view mirror', 'steering wheel');
$arrFruits = array('apple', 'banana', 'orange');
To use the arrays, there are tons of functions:

WRT functions: while I could see how this would seem like a good idea because of the symmetry in what's going on at a very high level of abstraction, I would be against including it in a language. I don't particularly like it for arrays, but it does make it easy to add items into an array, which happens pretty often in development, especially when writing exploratory code. Function signatures, on the other hand, probably aren't changing nearly as often. At the very least, I wouldn't want to encourage people to make functions with many parameters, as it's normally a sign of poor design. This wouldn't explicitly do so, but would do so implicitly as it's only real purpose is to make it easier to add things. As far as the supporting-a-leading-comma thing goes, I'm pretty ambivalent on it. I don't really like the style outside of Haskell code, but that's just a preference. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Try print_r($arrUsers);
also, the $line is an array of the CSV, so you're storing an array,
within the array $arrUsers.

foreach ($user as $val) {
echo $val . br /;

You are echoing out an array. If you use something like print_r() or var_dump()
you will see the array elements

But if you can suggest me a more efficient way to do it, I will definitely look into it. Are you also new to programming in general? If so, I suggest spending some time studying up on programming concepts and design patterns. I do understand the idea of just get the job done, but without basic knowledge, the result is not going to be very good, and likely lead to maintenance nightmares down the road. As I don't really understand what it is you're trying to do, it's hard to make concrete suggestions. From your very brief description, it sounds like you have one script that takes the form submission and populates an array, which you want to share with another script. Typically, data sharing between scripts is accomplished in a few different ways: 1) use of session variables (which requires the script to invoke session management) B) storing the information in a persistent data base (e.g. MySQL) iii) storing the information in a transient data store (e.g. a temporary file). There are different ways to format the data in the file, including as php script (so you can include the file), JSON, YAML, etc. d) passing the information to the second script via a query string or a post data buffer Any of these things require understanding of the mechanisms and implementation idioms involved. Choosing a particular implementation depends on several variables in your overall design and implementation environment. A mailing list is a poor way to transmit this information, which is why most of it is documented elsewhere.

You should probably get used to dealing with the array variables.
However, you can also look at the extract() function. It won't do
exactly what you want, but it will pull the array keys/values into the
current symbol table. Use with caution (note the second parameter to the
function).

Well, It occurs to me that you can't code in PHP without getting use to
dealing with arrays. ;-)
I just much rather like typing:
input name=f_email value=?PHP if (isset($t_email)) { print
htmlspecialchars($t_email);} ? /
Instead of:
input name=f_email value=?PHP if (isset($_GET['f_email'])) { print
htmlspecialchars($_GET['f_email']);} ? /
or
if ($t_ok) {
}
instead of:
if ($_GET['f_ok']) {
}
Save's a lot of typing time as far as I can tell.

Tommy, excellent.. I had just rewrote your first suggestion:
foreach ($a_formvars as $key = $value) ${str_replace('f_', 't_',$key)}
= $value;
(which works)
but I like that you are only affecting the vars that *begin* with
$match. I suppose the above would also work with $_REQUEST.
Shawn, I don't know if I have a good reason, other than I rather like
working with string vars instead of array vars from $_REQUEST for
(sticky forms and conditionals). I can check/verify them as well in the
process.
Thanks to all that posted.. I always learn from the skin the cat game.

I advice strongly against str_replace if you're looking specifically 'f_' at
the __beginning__ of the string. substr would guarantee it.

I realize this would be a major change, so that's why I also mentioned it as an addition to the language. I'm sure it's just what you're used to, but still being new to all this, it just makes sense (to me anyway) to have different symbols for different variable types: $scalar @array #hash Since the @ sign is already reserved, maybe there's another symbol that would work better? I don't know. These are just ideas that I came up with while reading and I thought I'd throw it out there to see what others thought. I like the idea of a naming convention, so that's what I'll do in my scripts. I also appreciate the heads up on is_string(), is_array(), and var_dump(). Thanks again, Marc PHP recently introduced namespaces to PHP5. One of the issues at the time was the namespace separator. Do to all the common symbols already being used, it was necessary to re-use one and the context dictates its intent. So whilst \n is the newline character, in the namespace string below namespace my\namespaces\are\here; the \n is not a newline. With that, there are no common symbols available. The Hungarian Notation [1] was what I was taught all those years ago when I learnt standard C programming. I've kept that with me through to PHP. Some say it is redundant in PHP. I suppose this is true, but it works for me and doesn't really get in the way. One thing to remember though is that PHP is a loosely typed language. Having a mechanism which would somehow enforce the type based upon a symbol would certainly be a different way of working for PHP. This is mentioned in the [2] and is suggested to be a poor way of working due to the lack of symbols in general. Regards, Richard.

I don't know if the PHP community has any standard convention.. but I would suggest something like: $a_foo (for arrays) $f_foo (imploding into form variables) $s_foo (string variables) $db_foo (variables coming from databases perhaps) etc..

Thanks,

PHP is a loosely typed language, so you can have a variable that,
throughout its lifetime in an app, is both a scaler (integer, string,
etc) or an array. For example:
?php
$message = hello world;
echo $message;
$message = array('hello', 'bob');
echo {$message[0]} {$message[1]};
?
There are functions you can use to determine the type of a variable,
such as is_string() and is_array() and you can use var_dump() in debug
statements to quickly see the type of a variable. I think changing
something as integral as a variable prefix would break a lot of code
which makes use of the loose typing, and would cause much more confusion
further down the line.
Also, as you may have guessed, the @ symbol is already in use at the
moment. In PHP it ensures that minor errors are silently ignored. For
example:
@executeSomeFunction()
would run that named function, but ignore any minor errors and warnings.
You'll typically find it used a lot in calls to mail() as that can be
flaky on some systems due to a number of factors outside of PHP.

Because the array is not formed until after the explode you cannot do it

$ret[] = $arr[$i];
}
// Return the array
return $ret;
}
/**

// but only if the number isn't zero
if ($pos !== 0) --$pos;
}
// Return the single position if it exists

I couldn't find out this answer anywhere, that's why I posted here.
Unfortunately, no --- at least, not yet. Chaining discussions
come up now and again, so it's quite possible that future versions of
PHP will have something similar. That said, for now you could do
something like this:
?php
/**
* mixed return_item( string $car, mixed $pos )
* - $str The original string
* - $charThe delimiting character(s) by which to explode
* - $pos The position to return
* - $shift Whether or not we should see 1 as the first array position
*/
function return_item($str,$char,$pos=null,$shift=false) {
// Make sure $char exists in $str, return false if not.
if (!strpos($str,$char)) return false;
// Split $char by $str into the array $arr
$arr = explode($char,$str);
// If $pos undefined or null, return the whole array
if (is_null($pos)) return $arr;
// If $pos is an array, return the requested positions
if (isset($pos) is_array($pos) !empty($pos)) {
// Instantiate a second array container for return
$ret = array();
// Iterate
foreach ($pos as $i) {
// This is just in case it was given screwy or a number as
a non-integer
if (!is_int($i) is_numeric($i)) $i = (int)round($i);
// Make sure $i is now an integer and that position exists
if (!is_int($i) || !isset($arr[$i]) || empty($arr[$i]))
continue;
// If all seems okay, append this to $ret
$ret[] = $arr[$i];
}
// Return the array
return $ret;
}
/**
* If $pos is a number (integer or round()'able number),
* we'll go ahead and make sure the position is there.
* If so, we'll return it.
*/
if (is_int($pos) || is_numeric($pos)) {
// This is just in case it was given screwy or as a non-integer
if (!is_int($pos)) $pos = (int)round($pos);
// If we want to start the array count at 1, do that now
if (isset($shift) ($shift === true || $shift === 1)) {
// but only if the number isn't zero
if ($pos !== 0) --$pos;
}
// Return the single position if it exists
if (isset($arr[$pos]) !empty($arr[$pos])) return $arr[$pos];
}
/**
* If we've failed every case, something is either
* wrong or we supplied bad data. Return false.
* Either way, feel free to add some trigger_error()
* stuff here if you want to have the function hold
* your hand.
*/
return false;
}
/**
* Some simple examples
*/
$foo =
'apple,banana,carrot,orange,carrot,lettuce,tomato,beer,carrot,idiot';
return_item($foo,',',7); // Returns 'beer'
return_item($foo,'carrot',0); // Returns 'apple,banana,'
return_item($foo,','); // Returns all items in an array
return_item($foo,',',array(0,'2',6.6)); // Returns array: apple,carrot,beer
return_item($foo,',',1,true); // Returns 'apple'
?
Of course, as with almost all code I submit here, it's typed
directly into this window and is untested, so you use it at your own
risk, your mileage may vary, see a doctor if you have an erection
lasting more than four hours, et cetera.
Happy Friday, all.

First at all, I wouldn't use 1 or 2 for defining important informations.
use something like
define('ORDER_GIFT', 1);
define('ORDER_PERSONAL',2);
If you want to check all values of your array you can use several
foreach loops like
foreach ($_SESSION['life_coaching_order'] AS $coaching_product = $tmp_array)
{
foreach ($tmp_array as $coaching_gift = $tmp_array2)
{
switch ($coaching_gift)
case ORDER_GIFT: break;
case ORDER_PERSONAL: break;
)
}
}
Personally I would prefer writing a class like
class Order
{
private $product;
private $gift;
private $quantity;
const ORDER_GIFT=1;
const ORDER_PERSONAL=2;
function getGift() {
return $this - gift;
}
}
using
$_SESSION['life_coaching_order'][] = new Order();
foreach ( $_SESSION['life_coaching_order'] as $order )
{
switch ( $order - getGift() )
case ORDER_GIFT: break;
case ORDER_PERSONAL: break;
}
I hope that will help you,

Re: [PHP] Array / form processing
Many thanks, Chris.
I have one additional question about this shopping cart project. I need
to make a submit button for the purpose of removing an item from the
shopping cart.
input type=submit name=submit value=Remove class=place_order/
What I am struggling with is to find an effective method for passing the
product serial number (auto_increment in the table it is stored in) so I
know which product the user is removing from their purchase. Then I will
just unset the session variable that matches.
What are your suggestion(s)?
Thank you your help with my original question Chris.

Re: [PHP] Array / form processing
input type=submit name=submit value=Remove class=place_order/ I don't know what the context is like, but you may be better off just using an entire form here with hidden fields. i.e. form target=... action=... input type=hidden name=submit value=Remove / input type=hidden name=product_so value=1234 / input type=submit value=Remove class=place_order/ /form Without knowing what else is going on in your page, and how the request is being handled on the server, it's kind of hard to give exact advice. :) Chris H.
Re: [PHP] Array question
I'd also like to add to that:
$array = array();
$array[] = 'text';
$array[2] = 123;
$array[] = 'hello';
Would output:
$array(
0 = 'text',
2 = 123,
3 = 'hello',
);
Note the missing index 1, as php makes a numerical index that is one greater
than the highest already in use. As the index 2 was explicitly created, php
made the next one at 3.

Ash

Mike,
$results[] will automatically push a value unto the end of an array.
So doing this...
--
$magic = array();
$magic[] = 'a';
$magic[] = 'b';
$magic[] = 'c';
-
is exactly this same as doing this...
--
$normal = array();
$normal[0] = 'a';
$normal[1] = 'b';
$normal[2] = 'c';
-
And yes, in your example $results[] would be equivalent to $results[$j]

What PHP magic is at work here? Mike: That's just a shorthand way to populate an array in PHP. One of the reasons for this feature is that somewhere in your code you may not know what the next index should be. So, if you use -- $results[] = $next_item; -- then the $next_item will be automagically added to the next available index in the array. So you may be right in calling it PHP magic because I have not seen this in other languages. Understand?

Dear Bob McConnell,
Thank you for your reply.
I really post the same message eight times because of the first e-mail
authentication.please remove the extra e-mail in your free time.
There are two servers ,the first installation of 32-bit linux(RHEL),the
second installlation 64-bit linux(CENTOS).
PHP version on 32-bit linux(RHEL):5.2.7
PHP version on 64-bit linux(CENTOS):5.2.13
I found this problem,because the software transplantation.In the 64-bit
systems,the array seems to always have limited capacity. I'm not sure that is
php version problem or need other configurations.
I suspect it's just different configuration.
That said, I've generally found that 64bit versions of PHP need more
memory than their 32bit equivs, so perhaps all you need to do is
something like:
ini_set('memory_limit', '50M');
and you'll be fine.

Try this:

If you want the form to retain the values, try this:

You need to iterate that array, as that holds the values of everything
sent by the browser

The painDesc array is what that should be iterated.

Re: [PHP] Array form processing
Am I on the right track? I don't know what to do with the second FOREACH
?php
foreach($_REQUEST as $key = $val) {
$$key = $val;
echo $key . : . $val . br;
if ( $val == Array ) {
$i=0;
foreach ($val) {
echo $val[$i]br;

Think about it...
You would not ?php echo $_REQUEST; ? and expect to get the value of any form
field would you. No, you wouldn't.
Given the following form...
form
Titleinput type=text name=title value= /br /
Subjectinput type=text name=subject value= /br /
input type=submit name=submit value=Send it! /
/form
on the processing page, I would access those variables by writing the following.
echo $_REQUEST['title'];
echo $_REQUEST['subject'];
With that said, going back to your issue, you would do this:
if ( $_REQUEST['painDesc'] count($_REQUEST['painDesc']) ) {
foreach($_REQUEST['painDesc'] as $key = $val) {
echo {$key}:{$val}br /;
}
}

If I were to hazard a guess as to the why of the current functionality, I would say converting an integer string to a real i nt is optimal with respect to both memory and processing when trying to find values by key. As for floating points... Due to the inability to accurately represent some floating point numbers in binary, one would often not get what one expects even when converting to a string. So maybe integer was chosen since it was more optimal than a string.

Thanks!
Group them??
How about this
while ($row = mysql_fetch_array($theData[0])) {
$col1[lookup($row[1])][] = $row[0];
which, using the data you showed, will give you this
Array
(
[ARMENIA] = Array
(
[0] = 52
)
[CANADA] = Array
(
[0] = 215
[1] = 57
)
[COLOMBIA] = Array
(
[0] = 261
)
[EGYPT] = Array
(
[0] = 53
)
[INDIA] = Array
(
[0] = 62
[1] = 50
)
)

I was actually hoping to have them arranged like:
$col1[0] = INDIA
$col2[0] = 112
$col1[1] = CANADA

foreach ( $group AS $x = $y )
{
$col1[] = $x;
$col2[] = array_sum($y);

I would probably do this:
$col1 = $col2 = array();
while ($row = mysql_fetch_array($theData[0])) {
$country = lookup($row[1]);
if(($found = array_search($country, $col1)) !== false) {
$col2[$found] += $row[0];

$col1[] = $country;

Although I myself would prefer it to be in this format:
$result = array();
foreach($rows as $row) {
$country = lookup($row[1]);
if(isset($result[$country])) {
$result[$country] += $row[0];
} else {
$result[$country] = $row[0];
}
}
Which would give:
array
(
INDIA = 112
CANADA = 272
//etc...
)
Then to use, just:
foreach($result as $country = $value) {
echo $country . ' ' . $value; // or whatever
}

Often when outputting csv, I usually do something like this:
?php
$fp = fopen('php://output', 'w') or die('Could not open stream');
foreach ($data as $row) {
// Assumes that $row will be an array.
// Manipulate the data in $row if necessary.
fputcsv($fp, $row);
}

So far, it has worked pretty well and is much faster than any other
way I have found to output the CSV data by iterating through the
arrays manually.

An interesting idea. I'd do:

If it's very simple data that works, but it doesn't allow for the
optional enclosure characters that fputcsv() uses in cases where a
data element includes the column and/or row delimiter characters. I
had originally written something using an array_map callback that did
the optional enclosures as needed and then used echo implode() as you
suggest, but found the solution I posted was shorter and faster. YMMV

Yeah, was considering that point as well. I'd use the echo if the
array values are getting modified anyway. Otherwise your solution is
probably simpler.

Re: [PHP] Array to csv or excel in php
For non-simple data I have been using PEAR's File_CSV package. It's
proven itself very useful in
regards to not having to determine in my own code whether something
needs to be quoted etc etc - especially if the output CSV needs to be
wholly RFC 4180 compliant.
The documentation of it is rather minimal - at the moment you are
dependant on the test/example files and the API docs but grokking how
to use it is rather easy.

RE: [PHP] Array differences
No because that only does a one-way comparison. It only tells me what's missing from $array2. I need it from both arrays. That's why I'm comparing 1 versus 2, then 2 versus 1, and then doing a merge/unique on the result. $array1 = array(1, 2, 3, 4, 5, 6); $array2 = array(1, 3, 2, 8, 9); $result = array_diff(array_unique($array1 + $array2), array_intersect($array1, $array2)); = (4, 5, 6) Versus: $array1 = array(1, 2, 3, 4, 5, 6); $array2 = array(1, 3, 2, 8, 9); $diff1 = array_diff($array1, $array2); $diff2 = array_diff($array2, $array1); $result = array_unique(array_merge($diff1, $diff2)); = (4, 5, 6, 8, 9) This second $result is what I want. So far I haven't noticed any problems doing it this way ... yet. I'm sure someone will tell me otherwise.

RE: [PHP] Array Search Problem
Hi,
At the time when I am writing this, looks like I already got the functions I
needed. It turned out that I had to use some array_combine, sorting the items
by keys instead of values as well as using array_keys to get the values I
needed.
Thanks for pointing me towards the right direction.

(almost) all the tricks are in the comments of the help page for a
function, on php.net
but all functions accept only a given (and usually documented) set of
parameter(type)s, so you'll probably have to prepare the var, or even
call the function in a loop, outputting to yet another descriptively
named array that'll be used as wanted list later in the code.

Yes, I found a recursive way to find out the index like I wanted, by
doing something like
$from = explode(-, $from);
$state_colors= explode(-, $state_colors);
$change = explode(-,$change);
$count = count($new_array);
$i=0;
foreach ($new_array as $key = $value){
echo $i . . $key . is . $value . miles awaybr /;
$i++;
}
You can see it is not very elegant, and plus, I created the $new_array so I
could do the ordering according to the values of the change array. I can
tell that since this is not a single array, which is probably why
array_search does not work.
Since I don't need the value of my new_array here, I am still finding
out how to strip off the values here without having to flatten my array.
Is what I am trying to do here possible? Or, is there a trick in
array_search that I could use to find the index without having to strip off
anything?
Thanks for your help.
