My framework does require PHP 5.3, and, honestly that has caused some pain in some situations to get that supported. However, using namespaces does offer some flexibility that naming conventions can't. If the objects in your framework make use of frequent static method calls, maybe it's worth it. For instance, if you've used the naming convention, you might have to call a static method like below: App_Util_DB_Query::Insert(); Namespaces allow you to shorten subsequent calls, such as: use App\Util\DB\Query as Query; Query::Insert(); Just a quick couple thoughts on the decision. Both have their strengths :) Adam On Mon, Mar 1, 2010 at 11:14 AM, Auke van Slooten a...@muze.nl wrote: Hi everyone, I'm doing a small hobby project to better my understanding of php5, specifically php5.3 and I'm wondering when a namespaced project is better and when it is better to simply use a prefix to all class names. I've been trying to get a feeling for what is considered the best practice, but most of the pages dealing with namespaces start with the assumption that you are building a complex application with lots of modules and say things like: Namespaces should be all lowercase and must follow the following conention: vendor\package_name\ (thats from the php.standards mailing list btw) In my case the project is a single module, single php file, with about 6 classes. It is an OO wrapper for PHP's xmlrpc methods (client and server) and meant to be used in a number of different projects. Is it considered a good idea to use a namespace in such a case? And if so, what should that be? I've named the project 'ripcord', and used that as a namespace as well. I could probably name it 'muze.ripcord', but somehow that feels less 'open' to me.

Using the Zend AutoLoader, my classes are structured so that Namespace_Package_Class_Exception is available in \includes\Namespace\Package\Class\Exception.php But having those long names in the SOAP WSDL file were a bit cumbersome.

[PHP] svg 2 gif/png
I'm moving all of my dynamic image generation to svg. Not only does it look better, but it is less resource intensive on my server allowing me to generate the svg on demand instead of pre-generating (via cron) twice a month like I had to do with gd dynamic generation. However, some browsers *cough*IE*cough* do not support SVG, so I still need png or gif fallback (I'll decide which after investigating size difference). Example SVG to convert - http://www.shastaherps.org/map/map22.svg Using convert from ImageMagick in the CLI is fast enough that I may just use the ImageMagick php module and do the fallback dynamic for the IE users, but I've run into a bit of a snag - it seems that ImageMagick doesn't understand xlink. IE running convert --size=800x574 map22.svg map22.png on above file results in a nice pretty map with the county and text, but the colored hexagons are not displayed. Is there an easy way around this? IE a php class/function that understands SVG w/ xlink and can replace the use tags with the polygons they refer to? If not, I'll have to try to write one, but I'd rather not ... Thanks for suggestions. It is too bad ImageMagick doesn't understand the use tag and xlink, that is one of the more useful features of SVG that I have personally found, makes dynamic generation so much easier. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I just did, haven't tested yet, but this may work -
function use2polygon($use,$polygon) {
// get the xy coords
$x = 0; $y = 0;
if ($use-hasAttribute('x') {
$x = 0 + $use-getAttribute('x');

$points = preg_replace('/\s+/',' ',$polygon-getAttribute('points'));
$pointArray = explode(' ',$points);
$sizeof = sizeof($pointArray);
for ($i=0;$i$sizeof;$i++) {
$foo = explode(',',$pointArray[$i]);
$foo[0] = $x + $foo[0];
$foo[1] = $y + $foo[1];
$pointArray[$i] = $foo[0] . ',' . $foo[1];
}
$points = implode(' ',$points);
$newPolygon = $polygon-cloneNode(true);
$newPolygon-setAttribute('points',$points);
$use-parentNode-replaceChild($newPolygon,$use);
}
}
of course that requires domdocument and probably requires looping
through the dom node list backwards, but hopefully that will do it.

$src_ip[] = $row[0];
$dst_ip[] = $row[1];
$sig_desc[] = $row[2];
$rec ++;
if ( $rec == $recCount ) {

}
}
for ($i = 0; $i sizeof($src_ip); $i++) {
$tmpResult[] = $sig_desc[$i],$src_ip[$i],$dst_ip[$i]\n;
}
The external program is called like:
cat results.csv | theprogram outputfilename
Is there a way mimic this w/o outputting $tmpResult to a file first?

popen() either reads from a pipe or writes to a pipe, if I remember
well, not both. Teus.

$errLog = /tmp/errors.log;
$dspecs = array(
0=array(pipe, r),
1=array(pipe, w),
2=array(file, $errLog, a)
);
$encrypted=;
$procdata=;
$gpgproc = proc_open($gpg_command, $dspecs, $pipes);
if (is_resource($gpgproc)) {
fwrite($pipes[0], $data);
fclose($pipes[0]);
while($procdata = fgets($pipes[1], 1024)) {
$encrypted .= $procdata;
}
fclose($pipes[1]);
}
return $encrypted;
}
It works really well.

You get $b[0] = $a[1], and so on (as you would expect).
Wouldn't that be $b[0] = $a[0], with the value of $i being 1 *after* the
statement was finished executing? You used a post-decrement operator on $i
at the end of your statement, so I don't think that $i would be increased
before being used to index into the $a array.

something like this?
you can put it wherever you like and returns an array for further
processing. You could optionally add a second argument to set the index
to a name and check if the name exists to add 1 to the end of the name
so your indexes stay maintained.

Re: [PHP] Re: Memory investigation
That's not really what I'm after. Let me try an example:
function foo($id) {
static $foos = array();
if (empty($foos[$id]) {
$foos[$id] = load_foo($id);
}
return $foos[$id];
}
When load_foo() is slow (e.g., lots of DB traffic or remote-server calls
or whatever), such caching can have a significant performance boost.
Sometime after foo() has been called 15 times from 30 places in code,
when I get to the end of the request (or just every time I call foo()
would be fine) I want to be able to do something like:
$cost = get_memory_used_by($foos);
So that I can determine how much memory that caching is costing me over
the lifetime of the page, and determine if it's a worthwhile trade-off.

you can put it wherever you like and returns an array for further
processing. You could optionally add a second argument to set the index
to a name and check if the name exists to add 1 to the end of the name
so your indexes stay maintained.

[PHP] basic authentication and redirection
Hi there, In certain circumstances controlled by my users, I'd like to redirect my users to another site, a third party whom we have contracted with. The second site uses basic authentication with a simple username and password. Can I write my PHP code so my users do not have to login (or even know the username/password) on the remote site? This isn't intended to stop serious hackers, just enough security to stop casual passers-by.

[PHP] Best os shopping cart
Hi, I apologise if this is not strictly php related. What Open Source Shopping cart system do you recommend between osCommerce and Zen-Cart for ease of use and a php guy with dangerously little javascript knowledge? This is not for a massive shopping site, simply a cart to power a subscription sign-up page. Thanks for the advice. Haig

Re: [PHP] basic authentication and redirection
depends on how that site does its authentication... if it's a form, it may need an extra setting to allow you to go to a specific page on that site after authentication.

Re: [PHP] Re: Memory investigation
Currently it's mostly procedural with some components that are OO. I
suspect most of the memory sinks are large arrays (we have a lot of
them), but I am not certain of that. Hence my interest in more accurate
investigation tools.

You get $b[0] = $a[1], and so on (as you would expect).
Wouldn't that be $b[0] = $a[0], with the value of $i being 1 *after* the
statement was finished executing? You used a post-decrement operator on $i
at the end of your statement, so I don't think that $i would be increased
before being used to index into the $a array.
Try it!

[PHP] XMLRPC issue
Hi all,
I was upgrading php from 5.6 to 5.11 and came across one odd issue. Hope
someone could point out what is the problem.
Following code demonstrates it:
$xml = '?xml version=1.0
encoding=UTF-8?methodResponseparamsparamvaluelt;Test/gt;/value/param/params/methodResponse';
echo xmlrpc_decode($xml);
I suspect to get Test/ as a result, but for some reason and are
cut out and i'm getting Test/. So basically all entities are dropped
from response.
I have 2nd server running same OS (CentOS 5) which has been upgraded
first and it works as i suspect, code above shows Test/.
Any advice will be much appreciated.
Currently I have temporary workaround for this:
$xml = str_replace(array('lt;','gt;'), array('#60;','#62;'), $xml);
but would like to fix xmlrpc somehow.
Regards,
Dmitry Ruban
