You may also be interested in protovis, and raphael, both of which are
js libraries which make, or export, svg graphics :)

Hi,
We are going add a topology view to our Network Management System.
Our Network Management System is based on PHP, CakePHP, jQuery and other
web
related tools(middle tier written using C++).
So we are going to work with Scalable Vector Graphics.
We are looking for the best solution for doing that.
Are there any extensions, plugins, frameworks available for SVG related
things ?
not sure exactly what youre trying to accomplish, but obviously you could
use any number of vector programs over the cli from php.
you might also have a peak at the cairo library which php allegedly
supports (ive never tried it myself).

I have an email message
$msg = 'Name: $fname ' . ' $lname\n'
. "Phone: $phone\n"
. "Email: $email\n"
and it works fine, however in this message there are about 30 variables that
are being called...as such
. "Order: beefschnitzel $beefschnitzel\n"
. "Order: beefstrips $beefstrips\n"
. "Order: cheesesausage $cheesesausage\n"
. "Order: crumbedsausage $crumbedsausage\n"
. "Order: chucksteak $chucksteak\n"
. "Order: cornedbeef $cornedbeef\n"
. "Order: dicedsteak $dicedsteak\n"
. "Order: filletmignon $filletmignon\n"
I want to only send the message if the submitter enters an amount in the
form for the corresponding variable, instead of having a bunch of empty
messages. So I have been trying to use the empty() function as such:
. if empty($beefolives){''} elseif (isset($beefolives)) { 'Order: beefolives
$beefolives\n'}
But I am getting the error
Parse error: syntax error, unexpected T_IF
Can someone point me in the right direction?
Thank you

Less complication is better, reduce the code to the below. The empty
portion needs to be inside the parentheses. Also double quotes are
needed to make the vairable parse correctly into the value you want to
see
if (!empty($beefolives)) { echo "Order: beefolives $beefolives\n";}

How are these variables being given their values by php? If you're making use
of register_globals then you're asking for problems.
Perform some sanity checks on your data, like using a regex of /^\d+$/ to check
for numerical values, and turn globals off; its a security breach waiting to
happen.
Get the values from $_GET or $_POST and treat each one as malicious until you
know its within the bounds of your application as a real value.

It looks like you're trying to do something like:
$str = 'something' .
if ($somethingelse)
'another string'
else
'a different string';
For one thing, you can't put a conditional on the right side of a
concatenation mark (.). You'd have to do it this way:
$str = 'something';
if ($somethingelse) {
$str .= 'another string';
}
else {
$str .= 'a different string';
}
You also can't do:
elseif (isset($beefolives)) {
'Order: beefolives $beefolives\n';
}
For one thing, surrounding the 'Order...' line with single quotes will
cause the \n *not* to be interpreted as a newline. Second, your 'Order:
beefolives...' does nothing. You haven't assigned it to anything or
operated on that string in any way.
You might want to study up on single versus double quotes, the
concatenation operator (.), etc.

That's because you're concatenating. When appending to a
variable, you can't use constructs and conditions, unless using
ternaries:
. (!empty($beefolives) && is_numeric($beefolives) ? 'Order: beefolives
'.$beefolives : null)
However, for readability and ease of management, you might want to
try something like this. It makes at least two assumptions: you're
using a form post, and you understand that it's untested (as I'm just
typing it here into the body of this email).
<?php
// If we've posted our order
if (isset($_POST) && is_array($_POST['order'])) {
// Instantiate the $order variable
$order = null;
// Iterate the order quantities
foreach ($_POST['order'] as $k => $v) {
// If the field is set and the amount is a number
if (isset($v) && is_numeric($v)) {
$order .= 'Order: '.$k.': '.$v.PHP_EOL;
}
}
/**
* Note: in your example, you used single (literal)
* quotes and included the variables. That would
* literally print $fname and $lname.
*/
$msg = 'Name: '.$_POST['fname'].' '.$_POST['lname'].PHP_EOL;
$msg .= 'Phone: '.$_POST['phone'].PHP_EOL;
$msg .= 'Email: '.$_POST['email'].PHP_EOL;
$msg .= PHP_EOL;
$msg .= $order;
// And then handle the rest of your processing. Here, we just echo.
echo '<pre>'.PHP_EOL.$msg.'</pre>'.PHP_EOL;
}
?>

Hi all. Can use natsort($array1) to sort a single array of filenames into a
"natural "alphanumeric order - 1.php, 2.php, 5.php, 10.php, 20.php, etc.
But using array_multisort($array1, $array2, $array3) doesn't offer a natsort
option, so I end up with 1.php, 10.php, 2.php, 20.php, 5.php, etc.
Anyone have a solution to this limitation already? Nothing found in the
archives or Googling.
Thanks.
