[PHP] Question regarding OO
?php
/*
I have a question here regarding object orientation in PHP and any other
language.
Let's start with some hypothetical code:
*/
// --- 1st CLASS
class ParkingLot {
var size; // size in sq feet
var max_number_of_cars; // how many cars there is space for
function __construct($size, $max_cars) {
$this-size = $size; $this-max_number_of_cars = $max_cars;
}
};
cpark = new ParkingLot(5, 17);
// --- 2nd CLASS
class ParkingSpace extends ParkingLot {
var ps_ID; // ID of the parking space ( 1 .. max_number_of_cars )
var occupied_by; // ID of the car on the parking space
var st_time; // Unix time stamp set when the car parks
function __construct($car, $id) {
$this-st_time = time();
$this-occupied_by = $car;
$this-ps_ID = $id;
}
};
/*
OK, so i got a parking lot class and its subclass parking space.
Now the question:
I want a list of occupied parking spaces, where do I put that? One might put
it into the ParkingLot Class, but wouldn't that be a recursion (a child
instance in the parent class)?
*/
$occ_parking_spaces = array();
$occ_parking_spaces[] = new ParkingSpace('Joes Car', 8);
$occ_parking_spaces[] = new ParkingSpace('My Prshe', 17);
$occ_parking_spaces[] = new ParkingSpace('Toms Caddy', 4);
/*
After a while a method to print all occupied spaces is necessary. Correct me
if I'm wrong, but I usually add it to the ParkingLot class.
class ParkingLot {
// previous code ...
var $occ_parking_spaces = array();
function print_occ_spaces() {
var_dump($this-occ_parking_spaces)
}
};
What bothers me here is that I'm actually having a list of child classes in
the parent class, is there a better/correct way to do this?
I hope I made myself clear.

[PHP] IPv6 validation
Hello community,
I have been working with alot of IPv6 lately.
Now i was wondering of what there might be the best way to validate an IPv6
address.
Couldn't think of any working regexp, since even ::1 or :: is valid
(localhost), so i tried it the following way:
?php
//RFC 4291
//http://tools.ietf.org/html/rfc4291
function validate_ipv6($value) {
if (substr_count($value, :) 2) return false; // has to contain : at
least twice like in ::1 or 1234::abcd
if (substr_count($value, ::) 1) return false; // only 1 double colon
allowed
$groups = explode(':', $value);
$num_groups = count($groups);
if (($num_groups 8) || ($num_groups 3)) return false; // 3-8 groups of
0-4 digits (1 group has to be at leas 1 digit)
$empty_groups = 0;
foreach ($groups as $group) {
$group = trim($group);
if (!empty($group) !(is_numeric($group) ($group == 0))) {
if (!preg_match('#([a-fA-F0-9]{0,4})#', $group)) return false;
} else ++$empty_groups;
}
return ($empty_groups $num_groups) ? true : false; // the unspecified
address :: is not valid in this case
}
var_dump(validate_ipv6(::)); // false (wanted result)
var_dump(validate_ipv6(::1)); // true
var_dump(validate_ipv6(1234::abcd)); // true
var_dump(validate_ipv6(2001:DB8:0:0:8:800:200C:417A)); // true
var_dump(validate_ipv6(0:0:0:0:0:0:0:1)); // true
var_dump(validate_ipv6(0:0:0:0:0:0:0:0)); // false (wanted result)
var_dump(validate_ipv6(:::::::)); // false
(wanted result)
var_dump(validate_ipv6(2001:0DB8::CD30::::)); // true
var_dump(validate_ipv6(FF01:0:0:0:0:0:0:101)); // true
var_dump(validate_ipv6(bananas)); // false
var_dump(validate_ipv6(1:2:3:4:5:6:7:8:9)); // false
?
anybody with better ideas?

Re: [PHP] IPv6 validation
It will still take some time until every provider has PHP5 running, at least
where I am from. I have many customers who want me to get their sites
running on some cheap webspace they got along with their internet
connection. Then you have to tell them it won't work because of some problem
with the versions. I would love to write code for PHP5+ only.

Yes. It matches any character based on the latin 'a' that is not
followed by an 'e'. It keeps the pattern from matching the 'a' when it
immediately precedes an 'e' for the character 'ae' for words like
these:

of 'ae' in them. I'll leave that to you to resolve.)

I was intrigued by your example, so I played around with it some more
this morning. My own quick web search yielded a lot of results for
highlighting search terms, but none that I found did what you're
after. (I admit I didn't look very deep.) I was up to something like
this before your reply came in. It's still by no means complete. It
even handles simple English plurals (words ending in 's' or 'es'), but
not variations that require changing the word base (like 'daisy' to
'daisies').
?php
function highlight_search_terms($phrase, $string) {
$non_letter_chars = '/[^\pL]/iu';
$words = preg_split($non_letter_chars, $phrase);
$search_words = array();
foreach ($words as $word) {
if (strlen($word) 2 !preg_match($non_letter_chars, $word)) {
$search_words[] = $word;
}
}
$search_words = array_unique($search_words);
foreach ($search_words as $word) {
$search = preg_quote($word);

$search = preg_replace('/(ae|æ|ǽ)/iu', '(ae|æ|ǽ)', $search);

function normaliza ($string){

Re: [PHP] case and accent - insensitive regular expression?
The original problem was User X submits a character string A. A PHP scripts uses A to search for it's occurences in a DB, ignoring special characters. The result of ze search is a list of character strings M-LIST with matches. This list gets outputted to the user X, but before that all the matching strings should be replaced with 'span style=color: #FF'..'/span' If i clearly got the OP then he is using MySQL to perform the search. I guess he is doing it with MATCH. So MySQL already found the match and in PHP it has to be done again ... eg. The table has 2 entries, string1 and string2 .. string1 = 'Thís ís an éxámplè stríng wíth áccénts.' string2 = 'This is an example string without accents.' Now the user searches for ample: search = '*ample*' Both string have matches due to accent-insensitivity (AI). Now the result is outputted with highlighting .. *Thís ís an éx*span style=color: #FF*ámplè*/span* stríng wíth áccénts.* *This is an ex*span style=color: #FF*ample*/span* string without accents.* So since MySQL already did the job, why not get the occurances from it? I'm not an MySQL expert, but I know google and found something called string functions. Especially a locate function got my interest. http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_locate Now shouldnt it be possible to create a query that searches the db for matches and additionally uses the string function? I have no idea, but maybe some MySQL-expert out there has ...

The HTML Form submits to the same, a.php
Once the user submits the Form, a.php is called which INSERT's the row into
the mySQL Table. However, the row does not appear in the SELECT statement
table data unless I hit refresh on the page. (The INSERT function is
executed before the SELECT in the page).
I used the header() code that was suggested:

header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past

$ffile = 'a.php';
$time = filemtime($ffile);
header('Last-Modified: '.gmdate('D, d M Y H:i:s', $time).' GMT');
.. but it didn't help.
Everything is working fine except that the Browser is more then likely
caching the data and thus not allowing the newly inserted row to appear on
top when the SELECT is executed.

Not sure what to do - it's rather annoying. Novice users of the page would

The Last-Modified header tells the browser when the requested page was

is an example:
browser requests /test/test.php which is a simple php file without any
includes etc.
in this case
$file = '/test/test.php';
This wont work if $file outputs dynamic data, so only use it if the
content only changes when you change the file.
Now if you are using templates etc. obtaining the Last-Modified time is a
bit more complicated. If you use server side caching then you can chose the
cached file else you have to figure it out yourself.
And the RFC 2616 header specification says:
An origin server MUST NOT send a Last-Modified date which is later than
the server's time of message origination. In such cases, where the
resource's last modification would indicate some time in the future, the
server MUST replace that date with the message origination date.
So do not send a future date!

When the form submits and the page returns, the added record does not show

I'm imagining even after form submit, the Browser is caching the data and
displaying data from the Cache.
Is there a solution to this? Is there anything PHP can do to instruct the
browser not the cache the data?

[PHP] Reference or copy?
Hello everyone,
Many of you may be familiar with references in PHP. Now i read
somewhere in the PHP manual that creating references can take longer
than copies. PHP5+ also seems to reference a bit different thant PHP4
did.
Here is some working example code:
?php

I tested the code in PHP 4.4.7 and in PHP 5.2.5 and the results were
pretty much the same. Using references speeds up the script!
Occasionally obj2-with-references took longer than all the others. But
i don't know if that's to be taken serious.
Now if i do not need a copy, isn't it smarter to use references instead?
I'm grateful for any ideas, thoughts or experiences

Re: [PHP] Writing my own web based user forum
If I fully understood the question you were asking then no.
Since it seems you are using a database there is no need to serialize.
You can write a simple function that fetches user data from a DB query
and then creates the object.
If you are going to use sessions you will have to do that only when
the user logs in and for verification purposes of whatever kind.
You might think of something similar to:
http://webbytedd.com/b1/simple-session/
In your original post you did not mention a picture upload site so I
suggest it is about uploading pictures to the forum/attaching them to
a thread.
I do not really have an idea of how your site will be operating, but I
guess you analyze the GET parameters and include files according to
them.
Some code might be helpful to explain what you want

Re: [PHP] Internationalisation and MB strings
Oh right. Doing 1 measurement only is not even worth a theory.
Well, I'm wondering how much PHP can speed that result up, since we are
calling the same function with the same parameter 1 times. Wouldn't it
be even more realistic if we called it with changing strings?
?php
$iterations = 1;
$mb_array = array();
for ($i = 0; $i $iterations; ++$i) $mb_array[] = str_shuffle('œŸŒ‡Ņ');
$s_t = microtime(true);
foreach ($mb_array as $mb_string) {
mb_strlen($test_string, 'UTF-8');
}
$e_t = microtime(true);
echo 'pMB_STRLEN took : '.(($e_t - $s_t)*1000/$iterations).'
milliseconds/p';
$s_t = microtime(true);
foreach ($mb_array as $mb_string) {
strlen('œŸŒ‡Ņ');
}
$e_t = microtime(true);
echo 'pSTRLEN took : '.(($e_t - $s_t)*1000/$iterations).'
milliseconds/p';
?
MB_STRLEN took : 0.0525826 milliseconds
STRLEN took : 0.0020655 milliseconds
I could not find out how well str_shuffle supports multi byte strings in
PHP4, so I'm wondering if I did this right ..

You can't determine timing by simply calling each function one time. I
changed your script to the following:
?php
$iterations = 1;
$s_t = microtime(true);
for ($i = 0; $i $iterations; ++$i) {
mb_strlen('œŸŒ‡Ņ', 'UTF-8');
}
$e_t = microtime(true);
echo 'pMB_STRLEN took : '.(($e_t - $s_t)*1000/$iterations).'
milliseconds/p';
$s_t = microtime(true);
for ($i = 0; $i $iterations; ++$i) {
strlen('œŸŒ‡Ņ');
}
$e_t = microtime(true

The part that bothers me is that mkdir_recursive calls itself from within
itself.
I am not an expert on this particular type of thing, and maybe that is
allowed, but it seems wrong to me, and this error is being generated:
That's the point of recursion... to recursively call oneself!
Fatal error: Call to undefined function mkdir_recursive() in x.php on
line 1057
the call to mkdir_recursive() on line 1057 is made inside mkdir_recursive()
so it's impossible that the function doesn't exist ... unless the function
you posted is actually a method of a class, in which case some time in the
past
the project included a standalone function mkdir_recursive() which is been
removed. at least that would be my first/best guess.
Not sure why you're getting that error since it appears to be well
defined above... unless x.php is not the same file in which
mkdir_recursive() ha sbeen defined. I'll wager it's not... in which case
you need to ensure the file that contains the mkdir_recursive() function
declaration is included into x.php. BTW, FWIW, I wouldn't call the
above code good quality since it obfuscates its intent by using ||
hackishness. It's succinct but less obvious.
it's plain horrid, not to mention using is_dir() dirname() twice
unnecessarily,
providing no checks as to whether the path exists and is a file or whether
file
permissions are okay (if your gonna wrap mkdir() might as well do a proper
job) , etc.
worst of all the call to mkdir() is error suppressed ... a nice big wtf
waiting
to happen when it fails.
oh and there is absolutely no need to use recursion here, a while loop could
be used instead which would be more efficient.
lastly Stut pointed out that php5 negates the need for this function
altogether,
but you might still be stuck on php4 for some reason.
ain't it fun inheriting other peoples 'code' ;-)

Rob.

Re: [PHP] Alternative to HTTP_REFERER?
By definition: The referer, or HTTP referer, identifies, from the
point of view of an internet webpage or resource, the address of the
webpage (commonly the URL, the more generic URI or the i18n updated
IRI) of the resource which links to it.
More detail at:
http://en.wikipedia.org/wiki/Referer
http://tools.ietf.org/html/rfc2616
So is a redirecting page a referrer or not? I don't know. Had no time
to translate the gibberish.
I experimented a bit with it and the most suitable solution I found
was passing the referring page on with a GET parameter ...
## A page redirecting to test.php ##
?php
$location = (empty($_SERVER[REQUEST_URI])) ? 'Location: test2.php' :
'Location:
test2.php?ref='.urlencode(base64_encode(gzdeflate($_SERVER[REQUEST_URI],

Re: [PHP] Re: HTML5 canvas tag
I'm not very familiar with the whole thing yet but after looking at your site I find it quite interesting. So is it possible to render 3d vector based objects in the canvas and if so an entire 3d based website? Are there any 3d libraries yet like OpenGL for applications? It would be quite handy to describe 3d/2d objects or styles with a language like CSS. Do you think that will be possible in the near future?

Re: [PHP] RewriteRule
What's the point of using '{0,}' instead '*' ?
Well the thing is that with the {0,} more REQUEST_URIs are valid:
eg.
/blog
/blog/
/blog/17
/blog/17/
/blog/17/0
/blog/17/0/
AND additional characters get ignored (like when it is necessary to
reload content with javascript, due to caching issues)

Re: [PHP] RewriteRule
You are absoloodle right about that. Although I'm not sure about their
greediness, which might be different.
I prefer the '{0,}' in my rewrite rules because I usually define the
max-length to prevent code injection.
eg.
# to make sure only the first 8 chars get passed on to PHP
RewriteRule ^blog/([^/]{0,8} index.php?a=$1 [NC,QSA,L]

Re: [PHP] Pure PHP Templating Class/AJAX Problem
Well after looking at the template thing you posted with your link it
seems to me like PHP is used to create working XML. So i wonder why
you are using AJAX here.
Now could it be that you use appendChild() ? That function would
simply add the XML again.
It's not easy to tell if you are not showing the JavaScript code ..
Still it simply depends on how you are importing the node you get from
XMLHttpRequest() or responseXML
Btw. importNode() is not working on all Browsers ..
Below is a code snipped I use for my AJAX class in JavaScript to copy
a node of one XML document (like from responseXML) into another. It
works in IE6+ and all W3C compliant browsers.
To make this work you will still have to make some ajustments.
xml_obj.prototype.xml_import_node = function(node, to_node,
all_children) { // cross browser importNode, NOTE: if toNode not
specified it will be set to current root_element
// appends node as a child to to_node
// if all_children is true then all child nodes will be imported too
/* NOTE TYPES:
ELEMENT_NODE = 1;
ATTRIBUTE_NODE = 2;
TEXT_NODE = 3;
CDATA_SECTION_NODE = 4;
ENTITY_REFERENCE_NODE = 5;

Re: [PHP] Re: 1 last error to fix before the application is done!
Personally, I very rarely see the point in using array_key_exists... It's a
function call and has overhead where as isset() and empty() are language
constructs and (I would hope) are much more efficient (although I've not done
any benchmarks)
# i don't know what's wrong with this ..
$foo = array();
$foo['bar'] = null;
if (array_key_exists('bar', $foo)) {
switch ($foo['bar']) {
case true:
//do something
break 1;
default:
//do something else
}
}
# if that's causing more overhead then let me see your benchmark, then

Re: [PHP] Inheritance of class methods
Using extends means that a class IS-A substructure of its parent class(es).

class tree extends plant { };
class apple_tree extends tree { };
apple_tree inherits all methods and attributes from plant and tree
So if there was a methods plant-growth() you can also call it from
tree and apple_tree
IS-A versus HAS-A
apple_tree IS-A tree
apple_tree HAS-A fruit called apple
So apple does not extend apple_tree because it is not a tree
EXAMPLE:
class apple {
var color = 'blue';
var inhabitant = 'worm';
}
class apple_tree extends tree {
var apples = array(new apple());

obj.style.left= (canvas.offsetLeft) + x + 3;
obj.style.top = (canvas.offsetTop + y) - obj.offsetHeight;
/**

document.body.onclick = function ()
{

}
/**

clicks on the graph?

RGraph.tooltip.offsetHeight;
} else { // create tooltip if not drawn yet
var obj = document.createElement('DIV');
obj.style.position= 'absolute'
obj.style.backgroundColor = '#E1';

obj.style.fontSize= '10pt';
/*
//alternatively one could create a tooltip css

document.body.onclick = function ()
{
RGraph.tooltip.style.left = '-999'; //older

Re: [PHP] Regex validation
After ceo posted about the imap function I was eager to try it out
and got rather disappointed pretty soon.
imap_rfc822_parse_adrlist() should not be used for email validation!
EXAMPLE:
?php
var_dump(imap_rfc822_parse_adrlist('! # $ % * + - / = ? ^ _ ` { |
} ~', ''));
?
The above code will output:
array(1) {
[0]=
object(stdClass)(2) {
[mailbox]=
string(36) ! # $ % * + - / = ? ^ _ ` { | } ~
[host]=
string(0)
}
}
Although
! # $ % * + - / = ? ^ _ ` { | } ~@example.com
would be a valid email address!
Without the '@example.com' it is not.
Have a look at the user comments at [1], where one user has further examples.

This looks like a valid localhost email address to me...
It surely is a valid localhost email address, but what most people
(and the OP) usually need is to validate a full email string with a
local and a domain part.
What should be valid email addresses according to RFC 2822 [1]:
!#$%*+-/=?^_`{|[EMAIL PROTECTED]

Not valid email addresses:
\@example.com
@@example.com
- [EMAIL PROTECTED]
Valid email addresses according to the Multipurpose Internet Mail
Extension (MIME) [2]:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
So for people who got to write code that also works on PHP4 it is not
very easy to validate an email address.
Even nice regex attempts like [3] fail since more and more mail
servers support the MIME hieroglyphs.
That's why I was pretty excited about imap_rfc822_parse_adrlist(),
since it runs in PHP4 if installed.
Which clearly is no substitute for the PHP5+ filter functions [4].

ob_get_contents() returns the outputbuffer as it is right now.
By calling ob_end_clean() buffering is stopped and the buffer cache released.
Still keep in mind that headers will still be sent when buffering the output.
here is a more complex
EXAMPLE:
?php
ob_start(); // starting the output buffer
?
html
body
!-- inner xml --
{{replace_me}}
/body
/html
?php
$output_buffer = ob_get_contents();
ob_end_clean();
session_start();
$_SESSION['test'] = time();
echo str_replace('{{replace_me}}', 'pThis is the replaced string.br
/SESSION[test] was set to: '.$_SESSION['test'].'/p',
$output_buffer);
?
Now we start the output buffer at the beginning of the script and the
session at the end.
It does not matter whether we close the PHP tag after starting the
ob_buffer. ( like with ? )
As long as we do not flush_end or clean_end the output buffering
process it will continue caching the output (except headers).
So session_start should work after actually outputting markup.
Another method could be like we did above the str_replace() [2] ...
EXAMPLE:
?php
$some_number = time();
$html = HTML
html
body
pTime: $some_number/p
p{{replace_me}}/p
/body
/html
HTML;
echo str_replace('{{replace_me}}', 'This string was changed by PHP', $html);
?
There is still plenty of other possible solutions. Keep on rocking

Re: [PHP] Sessions in object oriented code
I can't really understand that. Not sure if you understand my problem properly (if I've not explained properly). Anyone can give me some solutions please? Well as long as you don not provide any code it's all just wild guesses. What I tried was to show you a way of simply preventing the HTML from being sent to the browser before you include the session and/or cookie file. So you would just have to add the output buffering syntax to your existing code without changing all the scripts. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I am feeling a bit boneheaded now. How easy things can be.
This would not work if the character string after the number started
with a number too.
EXAMPLE
?php
$line = '017. 85 apples were sold to customer John Doe.';
# now ltrim would clearly cut off the '85 ' which belongs to the sentence.
var_dump(ltrim($line, '0123456789 .'));
?
So if one still wanted the speedy string functions a simple trim() [1]
or another ltrim() [2] would have to be added.
EXAMPLE
?php
$line = '017. 85 apples were sold to customer John Doe.';
var_dump(ltrim((ltrim($line, '0123456789.'), ' '));
?
Still there is one flaw in this construct:
If there was no white space between the '017.' and the '85 apples ..'
we get the old mishap again.
EXAMPLE
?php
$line = '017.85 apples were sold to customer John Doe.';
# note the difference above: '017.85 apples ...' this time
var_dump(ltrim((ltrim($line, '0123456789.'), ' '));
?
To stick with the string functions one could either use the
strpos($line, '.') + substr() [3] method or do it with explode(),
implode() [4]:
EXAMPLE
?
$line = '017.85 apples were sold to customer John Doe.';
$line = explode('.', $line);
unset($line[0]);
$line = implode('.', $line);
?
So it seems that the regular expressions posted are not a bad choice after all.

Re: [PHP] Grouping records
Ok, this looks quite databasey so I guess you will have a query like:
SELECT Rowid, Person, Timediff FROM transitional_records ORDER BY Timediff
I don't know what DB you use. let's say it is MySQL (the others are similar).
Always provide such things when asking for advice. Else it's not easy to help.
EXAMPLE
?php
mysql_connect(localhost, mysql_user, mysql_password) or
die(Could not connect: . mysql_error());
mysql_select_db(mydb);
$result = mysql_query(SELECT Rowid, Person, Timediff FROM
transitional_records ORDER BY Timediff);
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
// do something with the result here
}
mysql_free_result($result);
?
So what we get is an array like this ..
array (
Person = (string),
Timediff = (numeric)
);
Rowid, Person and Timediff are the only Values we need to get each
entries Groupid.
Now back to our example ..
EXAMPLE
?php
mysql_connect(localhost, mysql_user, mysql_password) or
die(Could not connect: . mysql_error());
mysql_select_db(mydb);
$result = mysql_query(SELECT Rowid, Person, Timediff FROM
transitional_records ORDER BY Timediff);
$persons = array(); // array containing each persons current Groupid
$rowids = array(); // array containing each row's groupid
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
$rowids[$row['Rowid']] = 0; // default for a row's groupid
if ($row['Timediff'] 60) {
if (!isset($persons[$row['Person']])) $persons[$row['Person']]
= 0;
++$persons[$row['Person']];
}
if (isset($persons[$row['Person']])) $rowids[$row['Rowid']] =
$persons[$row['Person']];
}
var_dump($rowids);
mysql_free_result($result);
?
So what is that script doing?
Well, first of all we set 2 arrays $persons and $rowids;
$persons is some sort of buffer for each person's current Groupid
whilst processing the table entries.
$rowids contains Groupid for each Row (set whilst processing)
WHILE LOOP:
First the current row's Groupid is set to the default value, which is
zero ( $rowids[CURRENT_ID] = 0 ).
Then we check whether the Timediff of the current row is greater than 60 or not.
IF it is the person's current Groupid is incremented (
$persons[CURRENT_PERSON] += 1 )
After the IF statement the current rowid's Groupid is changed to
$persons[CURRENT_PERSON] if that one exists.
As result we should get an array $rowids with the Groupid for each array.
So simply loop through that array and have the database SET the
Groupid somehow like this ..
EXAMPLE
?php
foreach ($rowids as $row = $group) {
echo SQL
UPDATE transitional_records SET Groupid = $group WHERE Rowid = $row;
SQL;
}
?
I hope I could help a little
Be more specific next time

Re: [PHP] RegEx to check for non-Latin characters
Hi Behzad,
I would try a different approach ...
EXAMPLE (UTF-8):
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd;
html xmlns=http://www.w3.org/1999/xhtml;

/head
body
?php
$username = '1aﺠﺟﺝﭻﭽﭼﭺ2b;
$encoding = 'utf-8';
$username = mbStringToArray($username, $encoding);
foreach($username as $char) {
if (strlen($char) == 1) echo $char.' is not a multibyte characterbr /';
}
function mbStringToArray ($string, $encoding) {
$strlen = mb_strlen($string);
while ($strlen) {
$array[] = mb_substr($string,0,1,$encoding);
$string = mb_substr($string,1,$strlen,$encoding);
$strlen = mb_strlen($string);
}
return $array;
}

/html
As you can see I'm using the multibyte string functions [1] and split
$username into a character by character array.
Then I use strlen() for which an UTF-8 char has a length 1. Note:
This might change with PHP6.
It also does not check for Persian characters only yet. You would have
to try something like this ...
