Thanks all, for the responses and advice.
After much research and trying out we decided to go with:
http://www.fengoffice.com/
its PHP based and also uses the EXTJS library. Its got quite a lot of
features (calendar, tasks, email, notes, documents, reporting) etc... with a
great AJAX interface and good functionality.
I'm using it within a government context and they're really enjoying it.
I had a to make a few coding adjustments to facilitate a language
switcher between English and French as is normal in a Canadian context.
Additionally, due to the lack of folder hierarchy for documents (they
rely on the tagging system which is inefficient for our document
management) we are abusing the workspace system to provide the folder
hierarchy. This necessitated a hack to prevent the aggregated view of
all documents within sub-workspaces at parent workspace levels. If
you're using 1.5 btw, you should update to 1.6 ASAP since it corrects
some issues with inherited group permissions.
Cheers,
Rob.

Hi,
I have the code as in the following, and I am trying to colorize the map. The
SVG File is located here:
http://upload.wikimedia.org/wikipedia/commons/5/5f/USA_Counties_with_FIPS_and_names.svg.
Looks like when I tried to modify the contents of the line, it does not seem
to take into affect. Thus, my map does not get colorized. Do I have to save the
file here? Or, is there something else I have missed here?
<?php
//We are outputting an SVG
header("Content-type: image/svg+xml");
$array= array();
$array2= array();
$array3= array();
$array4= array();
#Map Colors
$colors_array=
array("#F1EEF6","#D4B9DA","#C994C7","#DF65B0","#DD1C77","#980043");
$file = file("unemployment09.csv");
foreach ($file as $line) {
$chars = preg_split("/,/", $line);
$unemployment_rate = $chars[12];
array_push($array,$unemployment_rate);
}
//Calculate the number of elements in array
$total_num = count($array);
#Load the Map
$ourFileName= "USA_Counties_with_FIPS_and_names.svg";
$fh = fopen($ourFileName, "r") or die("Can't open file");
$contents = fread($fh,filesize($ourFileName));
$lines2= file($ourFileName);
#Color the counties based on unemployment rate
for ($i=0;$i<$total_num;$i++){
switch($array[$i]){
case ($array[$i] > 10):
$color = 5;
break;
case ($array[$i] > 8):
$color = 4;
break;
case ($array[$i] > 6):
$color = 3;
break;
case ($array[$i] > 4):
$color = 2;
break;
case ($array[$i] > 2):
$color = 1;
break;
default:
$color= 0;
break;
}
$color_class= $colors_array[$color];
array_push($array4,$color_class);
}
foreach ($lines2 as $line_num => $line2) {
$line_add_one = $line_num + 1;
if(preg_match("/<path/",$line2)) {
$rest = substr($lines2[$line_add_one],0,-3);
$colors_style = ";color:" . $array4[$line_add_one];
$rest = $rest . $colors_style . "\"";
}
array_push($array3,$lines2[$line_add_one]);
}
echo $contents;
fclose($fh);
?>
Thanks for your help.
Alice

You're reading the SVG contents into $contents, and also into $lines2 as
an array. You seem to be making changes to the array version on a line
by line basis, but then you output $contents, which is the original
contents of the SVG file! You need to output the elements of $lines2,
either one-by-one, or concatenate the array into a string and output
that.
Also, as a bit of advice, I'd try to make your variable names a bit more
descriptive than $lines2, $line2, etc. Trying to read through the code
and remember what variable does what could be a massive headache later
on!
Thanks,
Ash

I've used curl before to post "field" data to a server, but in this
case, I actaully need to post JSON data. However, when I run this PHP
script, I get nothing back. If I do this curl manually in Terminal,
it works.
I'm pretty sure the bug has something to do with CURLOPT_POSTFIELDS -
- - I just don't know what the alternative is. Basically I need to
post this data:
{siteUrl:\"http://testurl.com\",siteRss:\"http://feeds.news.mysite.com/synfeeds/collect/6/rss.xml
\",userName:\"testuser\",email:\"testemail\",siteName:\"testsitename
\",loginId:\"testloginid\}
to the url:
http://dpdev-ld03.myservercom:8181/linkmethod/signup?f=json&c=signupcallback
Any obvious mistakes below?
<?php
$ch = curl_init();
$timeout = 10; // set to zero for no timeout
$urltouse = "http://dpdev-ld03.myservercom:8181/linkmethod/signup?f=json&c=signupcallback
";
$fields_string = '{siteUrl:\"http://testurl.com\",siteRss:\"http://feeds.news.mysite.com/synfeeds/collect/6/rss.xml
\",userName:\"testuser\",email:\"testemail\",siteName:\"testsitename
\",loginId:\"testloginid\}';
curl_setopt($ch,CURLOPT_URL,$urltouse);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string); <-- shouldn't be
postfields, but some other curl option I'm guessing
$response = curl_exec($ch);
curl_close($ch);
echo $response;
?>
--- End Message ---
--- Begin Message ---
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query(array("data"=>$fields_string)));
Now on the server end $_POST['data'] will contain your json data.
if you just pass the $fields_string it can be read in the server end too.
$data = file_get_contents("php://input");
now $data will contain your json data.
It completely depends on the server you are interacting with. If it
needs json in a variable then pass it using http_build_query.
Otherwise just pass json as you are doing right now.
What you server expects?

Hello List.
I have been playing around with PHP, running a few tutorials and I
came across an error message I could not resolve.
The tutorial is Generating One Time URL's by Oreilly:
http://www.oreillynet.com/pub/a/php/2002/12/05/one_time_URLs.html
Basically the PHP code is supposed to read from a text file and write
to a text file and serve a text file all located in the "tmp"
directory of the server.
However, I receive the error that the referenced files in the PHP code
could not be found:
"Warning: readfile(/tmp/secret_file.txt) [function.readfile]: failed
to open stream: No such file or directory in/home/mysite/myfolder/
get_file.php on line 67"
Line 66 and 67 look like this:
$secretfile = "/tmp/secret_file.txt";
readfile($secretfile);
However, in the tmp folder, I have created a simple text file called
"secret_file.txt" so I know it exists and it has the permissions set
to 644, so it should be readable.
Can someone point out to me what I am doing wrong? Thanks,
--Rick

I have a flexible program, which can do many different things according to the
type of
data it is fed. Ideally the flexibility is achieved by calling different
functions,
though when the functionality is ill-defined I sometimes just include blocks of
code.
Ideally, from the point of program maintenance, each module should not be too
long --
preferably just a page or so. This doesn't raise problems in a compiled
language, but in
an interpreted language like PHP the programmer must decide whether to lump a
whole lot of
functions into a single large include file, or to include lots of little files
as the
particular functions are needed.
The first case can lead to memory bloat, as there are likely to be a lot of
unused
functions in memory on any given pass, whereas the second case may require lots
of little
files to be loaded.
Are there likely to be significant performance costs for either approach, and
what are
your feelings about the relative virtues of the two approaches?

Use a bytecode cache and stop worrying.

Rob.

It is highly unlikely you are going to create any significant "memory bloat".
Your code will likely be infinitesimal compared PHP's memory requirement.
I suggest 3 files, one with your configuration settings, so they are all in one
place and easy to find and change, another file with your functions and the
third file contains the code for handling the internet interface. Obviously, the
interface file controls everything by calling various functions as needed.

Hi,
Just went online and saw an SVG generated from Python, and wanted to
do the similar thing by loading the SVG into an PHP script. Here is the
script that I have:
<?php
#Load the Map
$ourFileName= "USA_Counties_with_FIPS_and_names.svg";
$fh = fopen($ourFileName, "r") or die("Can't open file");
fclose($fh);
?>
The problem is that my screen appears as blank even though I could open
up USA_Counties_with_FIPS_and_names.svg and see the entire US Map. Does
anyone know what I might have done wrong here?
Thanks in advance.
Alice

I move a number of sites from one server to another and one the one server we
had php4 and now we have php5 and since then my server seems to hang every time
there is a header, location redirect. Anyone have any ideas on how to resolve
this? Is there something I can easily change in the php.ini file that will
resolve this issue?
Thanks
