[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 + $use->getAttribute('x');
}
if ($use->hasAttribute('y') {
$y = 0 + $use->getAttribute('y');
}
// clone the polygon
if ($polygon->hasAttribute('points') {
$points = preg_replace('/\s+/',' ',$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.

It should work fine. You must change the session name (either using the session_name() function or by changing session.name in php.ini) before you call session_start(). Note that the session name and the session ID are two different things. -- Daniel Egeberg -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Help with exec.
I need to pipe some data to an external application.
I have this:
while ($row = mysql_fetch_array($theData[0])) {
$src_ip[] = $row[0];
$dst_ip[] = $row[1];
$sig_desc[] = $row[2];
$rec ++;
if ( $rec == $recCount ) {
break;
}
}
for ($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?
Thanks.

I believe you can use popen() to open "theprogram" and pipe to it the
content and read back the results. All without writing to any files.

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

I work by example :)
I can't find enough of an example to get me going with this.
I have this:
$glow = popen('afterglow.pl -c color.properties -s -e 3 -p 1 -l 2000 |
neato -Tpng -o /usr/local/www/test.png','r');
how do I feed my array to that?

Hi,
I have used this code to feed data to gpg and read back the encrypted
result, Im sure you can adapt it to your needs.
function Encrypt($data){
# http://www.theoslogic.com/scripts/php-gpg/
$gpg_command="/usr/bin/gpg $parameters";
$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.
Regards
Ian

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.

Re: [PHP] Re: Help with exec.
and its that easy!
it took me a minute to figure out; but all I had to do was:
if (is_resource($process)) {
for ($i = 0; $i < sizeof($src_ip); $i++) {
fwrite($pipes[0], "$sig_desc[$i],$src_ip[$i],$dst_ip[$i]\n");
}
fclose($pipes[0]);
fclose($pipes[1]);
proc_close($process);
}
thanks.

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.

RE: [PHP] basic authentication and redirection
[snip] 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. [/snip] Have a look at cURL (http://www.php.net/curl) as it will allow you to perform remote POST's which may be enough to get you through. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Or you can use JavaScript on an intermediate page to post directly to the remote site's login form. If JavaScript is disabled, just have a button "Please continue to XXX" which then performs the post tot he remote site.

you can put it wherever you like and returns an array for further

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.

[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: $xml = 'encoding="UTF-8"?>'; echo xmlrpc_decode($xml); I suspect to get "" 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 "". Any advice will be much appreciated. Currently I have temporary workaround for this: $xml = str_replace(array('<','>'), array('<','>'), $xml); but would like to fix xmlrpc somehow.
