Re: [PHP] How can an elephant count for nothing?
I guess the main reason for PHP to behave like this is to make life easier for many everyday situations. EXAMPLE: User input via GET or POST - usually string You compare it to some value - int/string or whatever So if a user posts '17' (string) and you compare it to 17 (int), unless you are using ===, PHP won't complain. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Help on caching an object.
Hello gang, First of all, yes I searched the mailing list's archive. My problem is very simple: I have an object that's definately called with every page request. It's pretty much the same for every unregistered/anonymous user. And it's not small. Alot of attributes are being set from DB queries etc. Now my idea was to do some sort of caching with PHP to speed things up. So I was wondering if anybody had experiences on this ... Of course, I considered using serialize(), but it seemed to me as if it could cause even more lagging since PHP requires the class to unserialize the object correctly. Then I would end up reading the class file, reading the searialized object and unserializing it. A 100 simple DB queries might be done in the same time or at least not much slower. Could it be that I'm looking at the wrong place? Should it be more like caching the queries or something similar? Thank you very much for everyone's effort in advance. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Basic bar code detection is not that difficult. You set a couple of virtual lines over the images and crawl them pixel by pixel. Then you count the black/white changes and the density of each change.

On the other hand it can get pretty complicated if you need error correction like a neuronal network would provide it. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Accessing the 'media' attribute in php
I have enough trouble getting my rather ancient brain around PHP, and was hoping that I could avoid getting involved with JavaScript. However it seems that it, or CSS, are the only possibilities for this case. If I understood you correctly what you want is to change the style of the page when the user is printing it. As others mentioned before all you would have to do would be adding a second style sheet for that purpose. EXAMPLE: link rel=stylesheet media=screen href=/styles/main.css type=text/css / link rel=stylesheet media=print href=/styles/print.css type=text/css / That would be all. Now if you want the user to have some kind of preview when clickin on a print the page button or link you need either JavaScript or PHP. The easiest way I could think of would be using the same print style sheet. For JavaScript have a look at this page ... http://www.quirksmode.org/dom/changess.html I think it should work in most modern browsers.

Re: [PHP] SELECT into array of arrays
How should I proceed? Thanks in advance for any suggestions.
Since you are looping through the result already, why not do it this way ..
$combinedArray = array();
for ($i=0;$icount($myArray);$i++) {
$sql = SELECT study,symbol FROM test WHERE study IN ('$myArray[$i]');
$result = mysql_query($sql);
if(mysql_num_rows($result) 0) {
while ($myrow = mysql_fetch_array($result)) {
if (in_array($myrow['study'], $myArray))
$combinedArray[$myrow['study']][] = $myrow['symbol'];
}
}
}
You should get an array like this ...
array(b2008 = array(A, B, C, D), b2005 = array(A, B, E))

[PHP] Short circuit evaluation and include
Hello everyone,
I'm posting this as a warning when using include() or include_once()
and checking their return values.
I'm refactoring someone else's code at the moment and got a short
circuit evaluation problem that made some problems ..
Here's the code:
FILE some_file.php:
?php
function some_function($file) {
$obj = false;
if (
!isset($file)
|| !is_string($file)
|| !is_readable($file)
|| !include_once($file)
|| !class_exists('some_class')
|| !is_a(($obj = new some_class()), 'some_class')
|| !method_exists($obj, 'some_method')
|| !$obj-some_method()
) return false; // line 14
return $obj;
}
$file = 'some_class.php';
some_function($file);
?
FILE some_class.php:
?php
class some_class {
function some_method() {
return true;
}
}
?
ERRORS PRODUCED:
Warning: some_function(1) [function.some-function]: failed to open
stream: No such file or directory in */some_file.php on line 14
Warning: some_function() [function.include]: Failed opening '1' for
inclusion (include_path='.;*/php/pear/') in */some_file.php on line 14
Note: I ran this code in PHP 4.4.9
It seemed to me like include_once() was not fully executed or
something when short circuited, because this code worked just fine
...
FILE some_file.php:
?php
function some_function($file) {
$obj = false;
if (
!isset($file)
|| !is_string($file)
|| !is_readable($file)
|| !include_once($file)
) return false;
if (
!class_exists('some_class')
|| !is_a(($obj = new some_class()), 'some_class')
|| !method_exists($obj, 'some_method')
|| !$obj-some_method()
) return false;
return $obj;
}
$file = 'some_class.php';
var_dump(some_function($file));
?
OUTPUT:
object(some_class)(0) {
}
So I was wondering how include() or include_once() are actually being
executed. I know they both return int(1) if no return specified in the
included file.
That's why I had a glance at the manual [1], where I saw this ..
Because include() is a special language construct, parentheses are not
needed around its argument. Take care when comparing return value.
Example #4 Comparing return value of include
?php
// won't work, evaluated as include(('vars.php') == 'OK'), i.e. include('')
if (include('vars.php') == 'OK') {
echo 'OK';
}
// works
if ((include 'vars.php') == 'OK') {
echo 'OK';
}
?
So when I added the paranthesis it worked ...
FILE some_file.php:
?php
function some_function($file) {
$obj = false;
if (
!isset($file)
|| !is_string($file)
|| !is_readable($file)
|| !(include_once($file)) // --- added paranthesis
|| !class_exists('some_class')
|| !is_a(($obj = new some_class()), 'some_class')
|| !method_exists($obj, 'some_method')
|| !$obj-some_method()
) return false;
return $obj;
}
$file = 'some_class.php';
var_dump(some_function($file));
?
Me, after an hour of coding without a line of code.

Re: [PHP] How to hide MySQL password in connection string in PHP script?
Robert Dodier robert_dodier AT yahoo.com wrote on 12-21-2003 Hello, I am experimenting with a wiki system (PhpWiki) which uses a MySQL database to store pages. It seems like a great system. The MySQL connection string is specified in a PHP script in the form mysql://FOO:[EMAIL PROTECTED]/baz. If I'm not mistaken the script has to be world-readable. But then, can't any other user (logged in to the host) just read the password? I share the host with other users, and the script has to be in my home directory, so I don't think I can guarantee that no other user can see it. Thanks for any advice, Robert Dodier I recently had the same problem on a shared host. The only solution I could think of was to have the server admin set an environment variable in an httpd.conf include file owned by root (chmod 600) [1]. EXAMPLE (mysql_pw.conf): SetEnv mysql_pw password SetEnv mysql_user username In PHP the variables then should end up in the $_SERVER array ... EXAMPLE (PHP): ?php var_dump($_SERVER['mysql_pw'], $_SERVER['mysql_user']); ? If this is impossible I can't think of another secure way on shared host systems, since other hosts usually are able to read your files. Maybe (if supported) one could SetEnv in .htaccess, so an attacker would at least have to glance into the PHP source code to find out where the password is stored. Still most people have it inside an include file and it works, I think.

Re: [PHP] Voting methodology
I once had to implement something similar for a client's intranet page. First we designed it to work without login simply by logging the IPs (static and in the 10.10.*.* range) to avoid people voting twice or more. Then the client wanted to have some statistics like what department voted for what (yeah, not very democratic i know). So we changed it have the user log in before voting. Now we could also make sure that only authorized users were voting, unless a user forgot to log out and a delivery guy was taking his chances (very unlikely). I think the thingy about online voting is to ask oneself how serious the result has to be. Getting a 99% bulletproof result might be quite time consuming (thinking of HTTPS, tokens, authorization, etc. here). So it all depends on what your client wants. //A yeti -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] getStatic
What would you do? I think PHP's string functions are pretty fast and even with large documents we are talking about a couple of extra microseconds on a modern machine. I once saw someone do pretty much the same as you are trying to do with strtr() [1], but I don't know if that function is faster than str_replace(). You should also consider that if you framework is going to manage someone's site one day then it could possibly be on a server with an older PHP version. I disagree with those on the list saying one should just stick to an existing templating framework, since it can be quite exciting to think some neat thingy out. Of course, most people (including me) hardly have any time at all to spend 1000s of hours on a more or less private project.

First of all .. always be careful with tainted data.
Like when you

be aware that this could be a security risk one day an ImageMagick
exploid is circulating.
At the first glance I saw a syntactical thingy that might cause problems ..
case default:
break;
In PHP switch for default this way ...
switch ($statement) {
case 1:
// do something
break;
default:
//do something else
}
then you forgot a semicolon
$orientation = $image-getImageProperty(exif:Orientation); // --- ; added
after that I got your script running.
Note:
At least turn error reporting on during debugging etc.
All error-reporting behavior can be modified at any level, so if you
are on a shared host or otherwise unable to make changes to files such
as php.ini, httpd.conf, or .htaccess, simply ...
ini_set('error_reporting', E_ALL | E_STRICT);
ini_set('display_errors', 'OFF');

Re: [PHP] Re: Some kind of Popup
One issue is I don't want to leave the space available on my regular web
page and would like to try not to overwrite something there - I'd rather
have a separate window of some sort that sort of floats over the web page.
Well, since Javascript does the Job anyways you don't have to load it
with the page when doing the div method.
You would only need this little addition to your css ..
style type=text/css
.div_win {
position: absolute;
width: 400px;
top: 100px;
left: 10%;
visibility: hidden;
}
/style
When user initializes the request by clicking a link
script type='text/javascript'
var div_window = document.createElement('div');
div_window.setAttribute('class', 'div_win');
div_window.className = 'div_win';
document.body.appendChild(div_window);
/script
Then you do some AJAX or JSON or whatever and apply it to the div.
You can also move the div around doing it somehow like this ...
http://www.quirksmode.org/js/dragdrop.html
Still, opening up a new window might be the simple solution after all lol.

sorry i think i did tell u wrong about it problem is not showing name
of it as exaclty i just wanted give a point to it thats not real
problem real problem is i want it be more unpossible when i give the
class's add function's higher value
In that case I would go for an algorithm using some kind of gaussian
distribution, like the Marsaglia polar method [1].
I once wrote something similar to what (I think) you are asking for ...
?php
function marsaglia($likelihood) { // adapted polar-method by marsaglia
if (!is_numeric($likelihood) || ($likelihood == 0)) $likelihood = 100;
elseif ($likelihood = 1) return 1;
// the greater likelihood, the less the chance of getting the thingy
$v = 2;
$u1 = $u2 = 1;
while ($v 1) {
$u1 = 1/(rand(1, $likelihood)*$likelihood);
$u2 = 1/(rand(1, $likelihood)*$likelihood);
$v = $u1*$u1 + $u2*$u2;
}
$p = $u1*sqrt((-2)*(log($v)/$v));
return ($p 0.85) ? 1 : (int)$p;
}
?
The best return of this function would be 1. Now if you call the
function with a high $likelihood (say 1000 and more) it gets less
likely have 1 returned ( gaussian ).
If you want to decrease the chance of getting values close to 1 then
you will have to increase $likelihood inside the function or
something.

$username = mbStringToArray($username, $encoding);
foreach($username as $char) {
if (strlen($char) == 1) echo $char.' is not a multibyte characterbr /';
}

$string = mb_substr($string,1,$strlen,$encoding);
$strlen = mb_strlen($string);
}

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 ...

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

Usually in PHP one does not take much care about the data types, but

string?)
also if you pass on $_GET params directly into ay bitwise operation
you might get some un-nice behaviour. So check them first.

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]
@@example.com
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].

Re: [PHP] Sessions in object oriented code
OK I guess it's somehow like this ..
form
?php
if (isset($_POST['submit'])) {
include('sessions.php');
// include sessions.php
}
?
!-- form innerhtml --
/form
now this of course is something very bad to do and it wont work.
One way to prevent markup from being outputted is using ob_buffer() [1]
EXAMPLE:
?php
$form = FORM
form
!-- form inner xml --
/form
FORM;
ob_start();
echo $form;
$output_buffer = ob_get_contents();
ob_end_clean();
var_dump(nl2br(htmlentities($output_buffer)));
?
So what we do here is simply start the output buffer befor echoing $form.
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

Now I wonder why you are creating a new tooltip each time the user
clicks on the graph?
Why not do it the following way?
RGraph.Tooltip = function (canvas, text, x, y)
{
try {
if (RGraph.tooltip) { // if tooltip already drawn
RGraph.tooltip.innerHTML = text;
RGraph.tooltip.style.left = (canvas.offsetLeft) + x + 3;
RGraph.tooltip.style.top = (canvas.offsetTop + y) -
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.border = '1px solid #333';
obj.style.borderRight = '2px solid #333'; // Set
the right and
bottom borders to be a little thicker - gives the effect of a drop
shadow
obj.style.borderBottom= '2px solid #333'; // Set
the right and
bottom borders to be a little thicker - gives the effect of a drop
shadow
obj.style.display = 'block'
obj.style.visibility = 'visible';
obj.style.paddingLeft = '3px';
obj.style.paddingRight= '3px';
obj.style.fontFamily = 'Tahoma';
obj.style.fontSize= '10pt';
/*
//alternatively one could create a tooltip css
class since this is
presentation
obj.className = 'tooltip'; //IE
obj.setAttribute('class', 'tooltip'); // W3C DOM
*/
document.body.insertBefore(obj, canvas);
RGraph.tooltip = obj;
document.body.onclick = function ()
{
RGraph.tooltip.style.left = '-999'; //older
opera fix
}
return RGraph.Tooltip(canvas, text, x, y);
}
return RGraph.tooltip; // return tooltip obj as stated in
functions comment
} catch(e) {
return false;
}
}
Secondly CanvasTextFunctions.letters() really is in a class of its own.

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

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;

Secondly the MIME type can differ from the extension (file suffix)
It's the same with uploaded files. Although the browser sends the MIME
type it might not be the right one, since browsers obtain the MIME by
checking the extension.

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
i believe it

You are absoloodle right about that. Although I'm not sure about their

I prefer the '{0,}' in my rewrite rules because I usually define the
