Re: [PHP] Rounded rectangle in php
It is certainly possible, but to my knowledge, there is no built-in method for doing so. After a quick Google, it looks like this has been done before: http://www.assemblysys.com/dataServices/php_roundedCorners.php http://us3.php.net/manual/en/function.imagefilledrectangle.php#42815 But if you're looking to reinvent the wheel: 1.) Given any three noncolinear points, you can construct a circle. (whose center is at the intersection of perpendicular bisectors of line segments connecting these points) 2.) Using imageline(), you can draw the sides of your rectangle, minus the corners. At the empty space where each corner would be you would have the ends of two lines--two points. 3.) Then you need to choose a third point that is between those two. (there is a certain line that the between point should lie on) 4.) Once you have three points, you can calculate the center and radius of the circle that passes through them. Then use imagearc() to draw the rounded corner. -- Greg On Thu, Jan 29, 2009 at 8:36 AM, Jônatas Zechim zechim@gmail.comwrote: Hi there, is it possible do make a rounded rectangle in php, i can do a ellipse, but i need a space between the corners, i need to make something like this: http://superbrush.files.wordpress.com/2008/03/086.jpg not the color and the shadows, only the form. zechim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Basically I somehow need to do a GROUP BY producer, and yet somehow at the same time, find out all the matching vintages (years), that go along with that group and return them the same time the producer group is returned. If I'm following you correctly, you have a column year in your group, and rather than returning just one year in your result set, you would like every year in the group.

The sockets extension is a much lower level interface to sockets than the fsockets/stream_ functions in PHP.

Your problem is that the sockets extension has no idea what you mean by ssl://; and since ssl://foo is clearly not a valid domain name, resolution fails.

Re: [PHP] require_once dying silently
the above won't work, as the parser will try to interpret $CFG and put it in the string first, In that case, $CFG is either null, or it is indeed an object. If it is a standard object, which I it appears to be, then a fatal error will be thrown because there is no __tostring() function. If it's null, then require_once is referencing a directory beginning with '-', again, there *should* be an error. Anyway.. I've seen $obj-property used many times in double quotes, and never had a problem with that working. Personally though, I always use the curly braces though because it highlights better in VIM :p Also, OOP is nice and all (not to start a thread about OOP again), but putting your config into an object seems a bit overdo to me.

Re: [PHP] limit mail() function
As far as I know, there's no way you can do this via PHP. PHP doesn't know about users on the system. Generally, PHP is run as an apache module, and thus the scripts are run as the user apache is running as. So to start with, you'd probably need to be running a Fast CGI + SuExec setup or something similar. I'm not sure how, or if there is a way to do this in postfix. The mail() function calls the sendmail binary, so one sort of hackish way might be to move this binary and write a wrapper script that keeps track of per-user rate limits, and then invokes the real sendmail binary. Of course, in this case, you'd also probably want to make sure the real sendmail binary couldn't be executed and that users could not write to the file that keeps track of the rate-limit. -- Greg On Tue, Apr 8, 2008 at 12:37 PM, Jordi Moles [EMAIL PROTECTED] wrote: hello everyone, first of all... i'm sorry if this has been asked like a million times before... but i've been looking for info about this and found nothing so far. anyway I've got a server with apache2 and postfix and php5 providing hosting to some clients.

Re: [PHP] limit mail() function
Pardon me, but that's one kludgy idea Hence my use of the term hackish. But really, is isn't all that kludgy. An software solution that implements this natively would have to keep track of the stats somehow; undoubtely via some sort of stats file. So the real difference is that two processes are run, instead of one. Yet, by the same wrapper logic, is it not kludgy that php invokes the sendmail binary, instead of using some sort of native php implementation? And again, by the same logic, the sendmail binary that comes with many MTAs is simply a wrapper to allow normal sendmail usage. postfix has rate-limitation facilities you can use for this I'm aware of several configuration directives that limit rate, none of which directly limit the send rate local users. Perhaps some kludgly or elusive trick involving multiple options would do the trick; I don't claim to be a postfix expert. Perhaps, instead of making empty statements, you might choose to enlighten me as per the exact configuration that will accomplish this. Of course, I spent some time googling, but it appears that not too many people know (or at least write about) how to implement such functionality. I did manage to find two interesting items in my searches: http://www.postfix.org/anvil.8.html http://www.opennix.com/email/postfix/policy/ratelimit.html The former doesn't appear to be magical, and from what my limited and apparently klugdy thoughts permit me to deduce, it seems to bear, conceptually, at least a degree (Celsius, mind you) of similarity to the aforementioned kludgy statistics idea... I didn't find any documentation regarding the implementation of anvil. And the latter, well that's not even a native postfix solution, so apparently, I have failed to find the alleged rate-limitation. All cynical, superficial, and sarcastic storming somewhat consummate, I can at last take solace knowing that I would, had you _suggested_ a better solution, or had I not, kludgy though it apparently was, put some effort into finding a solution, pardoned you.

Re: [PHP] require_once dying silently

Is it possible that something is going wrong between the definition
of $CFG-foo and when you require that could cause $CFG-dirroot to be
null? Then it would point to /lib/setup.php, which definitely
shouldn't exist and should thus throw an error, but maybe it's worth
looking into.
?php require_once('Have you tried including a file that definitely
does not exist?'); ? That would rule out any error reporting problems
anyway.
Have you tried something to the effect of ?php echo __FILE__ . '

print_r(get_included_files()); ? after the require_once() might also
help.
I've confirmed that the file setup.php exists and is readable.

Re: [PHP] Arbitrary mathematical relations, not just hashes
(sorry I just hit send on a blank email; I'm absent-minded)
First, in the strictest mathematical sense, a relation from a set $a to a
set $b is a subset of the cross-product $a x $b.
(obviously, the mathematical notation is not a great way to represent this
in a program.)
Hence, a relation is a set of ordered pairs: array(array('apple','red'),
array('ruby','red')) is a relation from the objects to the colors.
For a relation R from A to B, the inverse relation is defined by (b,a) for
all a in A and B in b.
Thus, the inverse relation of objects ~ colors would be:
array(array('red','apple'), array('red','ruby')).
A function is a special case of a relation: functions have the property that
if a in A is related to b in B by the relation R and a is related to c by
the relation R, then a = c.
It follows that mathematically, there is no function f:color-object.
As you suggest, each element of the relation colors~objects relation must
return a list in order to be a function.
So... How does SQL solve this problem?
SQL has indexes. You have a list of objects:
?
$objects = array(
array(
'name'='apple',
'type' = 'fruit',
'color' = 'red'
),
array(
'name' = 'ruby',
'type' = 'gem',
'color' = 'red'
)
);
?
Given a type, you would like to find all objects with that type. One way to
accomplish this might be:
?php
function locate($property,$value,$objects) {
$return = array();
foreach ($objects as $object) {
if ($object[$property] == $value)
$return[] = $objects;
}
return $return;
}
?
Obviously, the time increased to complete a search will increase with the
size of the $objects array. This is where the indexes come in: Suppose we
would like to easily be able to locate an object given a color, a type, or
its name:
?php
//array, indexed by $property. Each element is an array of numbers, n,
corresponding to $objects[n].
$indexes = array();
//properties to index
$keys = array('color','type','name');
//initialize
foreach ($keys as $key)
$indexes[$key] = array();
//this accomplishes the same thing as array_flip() ;)
foreach ($objects as $n = $object) foreach ($keys as $key) {
if (!isset($indexes[$key][$object[$key]]))
$indexes[$key][$object[$key]] = array();
$indexes[$key][$object[$key]][] = $n;
}
?
The above produces the following array:
Array
(
[color] = Array
(
[red] = Array
(
[0] = 0
[1] = 1
)
)
[type] = Array
(
[fruit] = Array
(
[0] = 0
)
[gem] = Array
(
[0] = 1
)
)
[name] = Array
(
[apple] = Array
(
[0] = 0
)
[ruby] = Array
(
[0] = 1
)
)
)
Conceptually, this is all SQL does.
Anyway... I wouldn't actually do any of that in an application. I'd probably
go with what Casey suggested.

The fgetc() function returns the character at the current position and increments the file pointer by 1. I haven't tried this, but perhaps using strpos would be faster?

[PHP] Re: [PHP-DB] php4 to php5
Sounds like you're talking about the register_globals functionality. It's a
php.ini setting that will cause $_POST['foo'] or $_GET['foo'] to be copied
to the global variable $foo. This is somewhat of a security risk, thus
disabled by default.
There's another superglobal array that you might find useful: $_REQUEST.
$_REQUEST consists of variables from $_GET,$_POST,$_COOKIE (in that order, I
believe).

function php5($var) {
if(ISSET($_POST[$var])$_POST[$var]) {
$newvar=$_POST[$var];

however I would like to do this for all variable, I tried iterating
through the $_GET and $_POST arrays but could not get it to work.
Anyway the main reason I am writing is:
- where the web page form uses the POST method, but there are parameters
in the URL after the ? sign, these 'get' parameters seem to stay there when
you submit the form from eg input type=submit button. So, let's say the
script will add a line if addlines=y, if before you submit the form you have
?addline=y in the URL you will continue to add lines according to the script
even though there is no hidden variable on the page called 'addline',
because every time you submit the form with POST you have addline=y in the
URL - if the script looks at GET variables then this will feed into the
script. This does not seem to happen with php4 - if the page does not
submit an 'addline' variable from a form field, it will not feed into the
script. So what's the rationale for that (the URL submitting the variables)
and what is the usual solution? The problem arises on this particular page
because of a mix of buttons, some are javascript and send the addline=y with
onClick.
