Huh, didn't notice the cross-posting. But no, you're not subscribed
to any new lists.
Since we're cross-posting, the translation of my sample would be
apropos. Here are a few different takes on a loopless versions in
Ruby. Given:
color = { :apple => :red, :ruby => :red, :banana => :yellow }
This is, I think, the most straightforward:
color.keys.find_all { |k| color[k] == :red }
But having to repeat the hash name is inelegant. Which leads us to this:
color.find_all { |k,v| v == :red }.collect { |p| p[0] }
Building up a list from the elements of a Hash would seem to be a
natural application of Hash#inject, although the fact that the inject
block has to return the accumulator makes it a little less elegant
than it could be, IMO:
color.inject([]) { |a,p| a << p[0] if p[1] == :red; a }
In Perl5 I don't have a better solution than the first one above:
my %color = ( apple => 'red', ruby => 'red', banana => 'yellow');
grep { $color{$_} eq 'red' } keys %color;

Without a database? I guess not. You'd still need at least SQLite.
But you are right, you could use ActiveRecord to obtain a nice object
oriented wrapper around the database so that it doesn't scare you.
Or, assuming you do store that data into a database table (of course
using indexes on both columns) you could use Perl and choose how to
access the data. With OO or without OO (horrrrrrors).

One of the reasons why you can't find them as easily is efficiency.
If people could ask for all items in %color whose value is 'red',
they would. Without noticing that it's much more expensive than the
other way around.
@items = grep {$color{$_} eq 'red'} keys %color;
is not too complex, but it complex enough to suggest that there is
more work involved. The only way both the direction could be equaly
complex would be to keep two hash tables internaly instead of one.
Which would double the memory consumption.
If you do need to do this more often you can build an inverse data
structure. Which if it was a one-to-one relation would be just
%inv_color = reverse %color;
in Perl, of course once the relation is many to one than the inverse
one will be more complex to build.
my %inv_color;
while (my ($k,$v) = each %color) {
push @{$inv_color{$v}}, $k;
}
and of course will be harder to work with. But there is no way around
that.
What is it you are actually trying to acomplish?

hello,
I am mostly familiar with php for serving up web pages; however,
recently i have been writing a local command line script on my WinXP
machine. I have spent the better part of this last week and all of
today trying to figure out a way to send a mouse click to a particular
window on the screen.
I first saw w32api.dll on the php.net site. However, I cannot find this
dll, but this searching took me to winbinder and php-gtk2. It seems
that I can only get winbinder to get (not send) mouse information: event
type and x,y positions. I am not too familiar with php-gtk nor creating
dlls.
I want to use my local php command line script on my winXP machine to
send mouse events (click) to a window. I am open to any ideas on how to
do this.
For C++ and VB there seems to be the SendMessage() function. Is there a
way to tap into that function from my php script?
winbinder has a function that wraps the SendMessage() function called
wb_send_message, but after literally 9 hours i quit.
Possible ideas:
-Load a dll with the dl() function? (Write the dll with VB or C++)
-use the w32api_register_function() in php somehow to 'tap' into windows
api functions.
-use a project that can assist me in this like php-gtk2 or winbinder
-maybe someone has a copy of w32api.dll
-something about COM objects, though i am really not familiar
I am throwing out this question to the community and wondering what your
suggestions would be for how to go about sending a mouse click event to
my windows api from a php script.
I am not interested in writing javascript as this is not a web application.
Any thoughts, comments, suggestions, about how to do send mouse events
from a php script will be much appreciated.
Thanks in advance,

Have you seen how PHP makes difference between private, protected and public
attributes of an object, into the session file ?
There are special caracters before them to recognize them.
So the question is : is PHP4 able to read such a session file ?
And how will it interpret them when we ask him to unserialize data ?
Cheers.

The question(s) should be "Why would you want PHP4 to read a PHP5
session?" and "Why would you expect it to work?". If you want to
transfer data between versions you may want to investigate XMLRPC. Or
perhaps the somewhat more verbose SOAP.

PHP list,
I have a large set of PHP scripts of my own design that outputs any
errors to text log files.
These scripts are deployed on a few different sites, at different
virtual hosting services. On one, I keep seeing this error in my log files:
Error Handler message: session_start() [<a
href='function.session-start'>function.session-start</a>]: The session
id contains illegal characters, valid characters are a-z, A-Z, 0-9 and
'-,' /home/domains/mydomainname.com/public_html/index.php 107
Before I show the content of index.php, I want to emphasize that no
other virtual host produces this error. My home testing environment
doesn't either. I have doubly ensured that the scripts are the same
across all environments. So there must be something in the interaction
of my scripts on that hosting service that is causing this error.
Here are the contents of index.php, trimmed of most comments for
brevity. Line 107 is where the last session_start() call is.
My question is why would this code trip an error on one server, but not all?
Thank you for any advice.
--- code ---
include_once '+site/Settings.php';
include_once 'Global.php';
set_error_handler(array('ErrorHandler','handleError'), E_ALL);
// initialize the output tree. This is the structure that receives all
the ouput and stores it in a tree form
// based on the HTML structure
HTML::initializeTree();
$userRequest = trim($_SERVER['REQUEST_URI'], "/");
if (Browser::supportsCookies())
{
session_start();
}
else
{
if (strlen($userRequest) != 0)
{
$sessionArray = Session::decodeSessionID($userRequest);
if (is_array($sessionArray))
{
session_id($sessionArray[0]);
$userRequest = $sessionArray[1];
}
else
{
$userRequest = $sessionArray;
}
}
session_start();
}

This will not do what you expect it to. Since 'John' is the first thing
in the string strpos will return 0 causing the condition to evaluate to
false.
As per the documentation for strpos you should compare the value *and
type* of the variable returned by strpos against false to check for
non-existance.

Since you said you wanted to know if it "contains 'john'", this
will find if 'john' (insensitive) matches any part of the name. So in
your case, it would match on both John and Johnston.

preg_* is overkill if you're just searching for a literal string. use
it if you're searching for any strings matching a pattern, part of
which you don't know. If you know the entire string you're looking
for, strstr() is both more efficient and easier to use.
Now, strpos() is more efficient still, but arguably more annoying to
use because of the "0 but true" issue that necessitates checking for
!== false.
Besides efficiency, the only difference between strstr() and strpos()
is what they return. strpos() returns the index of the first match,
while strstr() returns the entire string starting from that point;
it's the building of the copy of the string that causes strstr() to be
less efficient.
Both functions have case-insensitive variants stristr and stripos.
In each case, if the substring occurs more than once within the outer
string, the return value is based on the *first* occurrence. strpos()
(but not strstr()) has a variant that uses the *last* one instead:
strrpos() (r=reverse), which also has a case-insensitive version
strripos(). You can easily define a strrstr() though:
function strrstr($where, $what) {
$pos = strrpos($where, $what);
return $pos === false ? false : substr($where, $pos);
}
And for good measure, a strristr:
function strristr($where, $what) {
$pos = strripos($where, $what);
return $pos === false ? false : substr($where, $pos);

I wonder if using strstr() with strtolower() would be faster or slower.
<?php
$max = 10;
$it = 0;
while ( $it++ < $max ) {
echo "Attempt #{$it}<br />";
$string = 'John Doe';
$counter = 10000;
$new_string = strtolower($string);
$start_time_1 = microtime(true);
while ( $counter-- ) {
if ( strstr($new_string, 'john') ) {
### Found it
}
}
echo microtime(true) - $start_time_1."<br />";
$counter = 10000;
$start_time = microtime(true);
while ( $counter-- ) {
if ( stristr($string, 'john') ) {
### Found it
}
}
echo microtime(true) - $start_time."<br />";
}

While I don't really care much for a single selection about the
difference of less than 7/1,000's of one second, that's still good
information to keep in mind - especially when dealing with large-scale

Hi,
Do you guys how search engines like cookies? One site I'm working on now
requires the user to select which region he/she is from on the start
page. That value is stored in a cookie. So without cookies you can't get
past the start page. Does this leave the search engines at the start
page? Right now google only index the start pages on my site and I'm
trying to figure out why.
If I can't use cookies, how would you force users to select a region but
letting the search engine spiders in on the site somehow?
Hope this wasn't too off topic.
Kind Regards Emil

One way to do it would be to allow Google (and/or other search
engines) to access the site by bypassing the region-selection
entirely.
<?php
if(preg_match('/Google/Uis',$_SERVER['HTTP_USER_AGENT'])) {
// Allow Google to pass through.
}

Search engines won't come past that page. How about setting a default
region when a user enters a different page then your main page?

Hi,
Do you guys how search engines like cookies? One site I'm working on now
requires the user to select which region he/she is from on the start page.
That value is stored in a cookie. So without cookies you can't get past the
start page. Does this leave the search engines at the start page? Right now
google only index the start pages on my site and I'm trying to figure out
why.
If I can't use cookies, how would you force users to select a region but

Hello, I have run into a problem when trying to get the ssh2 bindings to
run on PHP. I have successfully installed libssh2 and have gotten version
0.11 of ssh2 to compile correctly using the patch obtained through the
'package bugs' page. However, when I load php, I get the following error:
dyld: NSLinkModule() error
dyld: Symbol not found: _zval_used_for_init
Referenced from: /private/etc/php_modules/ssh2.so
Expected in: flat namespace
Trace/BPT trap
I'm kind of a php novice so any advice you could give me would be greatly
appreciated. I'm running PHP v5.2.5 on Mac OS 10.5.2 and am more than
willing to provide you with any other details.
Cheers,
Michael Stroh

Re-run ./configure for libssh2 and see if there are any errors
there. The missing symbol in the compiled .so file
(_zval_used_for_init) I believe refers to Zend Optimizer, so you may
just need to reinstall that (and maybe a newer version).

Thanks for your advice Daniel.
I installed the new version of Zend Optimizer but then received the
following error:
dyld: NSLinkModule() error
dyld: Symbol not found: _zend_extensions
Referenced from: /usr/local/Zend/lib/ZendExtensionManager.so
Expected in: flat namespace
Trace/BPT trap
I checked the Zend forums and it is believed that they will not support
Mac OS 10.5 and thus the error. Is there another package I can use to
replace Zend for the purpose of ssh2?
Cheers,
Michael

If you're using it for Zend Encoder-encoded files, the answer is
no. If you just have it installed because it seems like a good idea,
then your best bet would be to comment-out the [Zend] section of your
php.ini and restart your HTTP server (Apache?) so that the changes
take effect. Then try the SSH code again.

Hi all,
My system is accessible through an index.php file. This file does a
bunch of includes to include global variables, which in function context
become available through the global keyword:
index.php
<?php
require_once "global_vars.php";
function f() {
global $global_var;
var_dump($global_var);
}
f();
?>
However, apart from access through the index.php file I want to be able
to include my index.php file from a function context:
<?php
function includeIndex() {
require_once ("index.php");
}
?>
The logical result is that variables that are globally accessible to
functions when the system is accessed through index.php are now in the
context of includeIndex() - so they're not global.
I want to fix this problem by not having the include inside of the
function context. How to go upon this?

In index.php rather than declaring vars like so...
$var = 'value';
...declare them in the $GLOBALS array like so...
$GLOBALS['var'] = 'value';
$var is then in the global scope regardless of where it was set.

That would work. However I'm looking for a more generic solution,
independent of the system that is being included. So basically I want to
be able to include a file in my function while stepping out of the
context of the function itself.

I'm not sure what you mean. If you're saying you want to include a file
from inside a function but for all parts of it to behave as if it were
being included at the global scope then I don't believe there's a way to
do it.
Maybe it would be better if you tell us exactly what you're trying to
achieve. I don't really see why my solution above would not work so I
probably don't fully understand what you're trying to do.

Some operations in the system are expensive or just take very long. As a
solution, every time such a request is made the system schedules itself
to be executed at a different moment. A cron job runs every night and
checks if there are any scheduled processes, and if so it executes them.
A process is defined by the state of the system when the process was
delayed (all super global variables make up for the state). The
scheduler restores the state and then includes the index.php file so
that the process can be executed.
Your solution would definitely work, however, the problem is that the
system is huge and designed in a terrible way. To search the code and
find all variables that have been defined in the global scope would be a
monstrous task that would take days.
Apart from that, it would be great if we can reuse this scheduler for
different systems without having to touch the actual system.
I do see a couple of solutions, but none are very elegant. You could,
for example, have all work done outside of a function. However, this
means uncoupling the functionality from the Scheduler object, which
means we get scattered functionality that belongs to the same logical
group - scheduling a process and invoking a process is done in different
files.

Was there a reason this was sent to the PHP list as well? Maybe
just a typo?

That's pretty vague, Noah. Is it unable to locate the file?
What's the error message you're receiving?
Also, what happens if you create two simple files in the same
directory like so:
<?php
// file1.php
echo "Okay.\n";
?>
<?php
// file2.php
include(dirname(__FILE__).'/file1.php');

It's Windows. From experience, I know that it provides little to no
error reporting in some instances. For example, if you're missing a
semi-colon and you have error reporting turned on, all you get is a
blank page - no other info. So, odds are is that he isn't receiving an
error message.

I'm not sure where you got that from, error reporting does not differ
between Windows and other platforms except where platform-specific
differences exist in the implementation (of which there are few).
What you're experiencing is probably the effect of the display_errors
configuration option. Look it up in the manual for details.
To the OP: Check that your include_path contains '.', if it doesn't add
it and see if that fixes your problem.

Pay no attention to the design or any of the other stuff, but this
is a development site on which I lay out tests and new things for my
employer:
http://www.brokenauto.com/
It has a vehicle drop-down list (AJAX).
