Not on binary files. For an image that's 4494 bytes, file/join/strlen gives
me 3512. And since file() on a remote file is downloading it anyway, you
might as well do it right:
$fp = fopen('http://example.com/image.jpg','r');

$image .= fread($fp,1024);

Hello,
I need to capture the contents of a Form into a text file format and
automatically allow the user to Save the file to his desktop.
Here is what I am intending to do:
* Capture the form contents and save to a temporary file. This works fine.
* Provide some method of the user automatically downloading this. How do I
get this download to happen?
I want the screen which says Open File or Save to come up and then the
user can basically save to his desktop.
It's not even necessary to save the form data to a file on the server
if you're just going to remove it after the user downloads the text
file. The key to this is knowing the proper HTTP headers to send, to
inform the browser that it should download a file. Then simply print
the desired form data to stdout, and it'll be fed into the file that
the user saves.
For example:
?
if ($action == 'Get Text File')
{
// Tell the browser to display a 'save file' dialog
Header('Content-Type: application/octet-stream');
Header('Content-Disposition: attachment; filename=formdata.txt');
// Print the text to be sent as formdata.txt
echo First text field: $firstfield\n;
echo Second text field: $secondfield\n;
exit;
}
?
form method=post action=?= $PHP_SELF ?
First: input type=text name=firstfieldbr
Seond: input type=text name=secondfieldbr
input type=submit name=action value=Get Text File
/form
Here, the form takes in two text strings, and offers them to the
browser as a file.

Displaying images in this fashion is fairly simple.
In the html, as you've already provided, set the img src=.. to a
PHP script, possibly with a query string. Then, your phpads.php3 would
be responsible for outputing the image data, along with the proper HTTP
header to tell the browser that you're sending it an image.
?
// phpads.php3
// Set the appropriate mimetype for the image
Header('Content-Type: image/jpeg');
$filename = '/path/to/file.jpg';

Preface to these ramblings: Exception handling is planned for the next
version of the Zend engine. For details, see
http://www.zend.com/zend/future.php
The nasty thing then comes in that if any task fails, I have to stop. So I
create a convention that every task returns 1 for success, 0 for
failure. Tasks can also be nested. So this gives me a structure like
this:
if ( ! GrabLock() )
return 0;
$retval = 0;
switch(0){ default:
if ( ! RunTask1() )
break;
if ( ! RunTask2() )
break;
if ( ! RunTask3() )
break;
$retval = 1;
}
ReleaseLock();
return $retval;
This works, but it is cumbersome, you have to be VERY careful and there are
other complications in terms of reporting sensible error messages when
tasks are shared.
This is probably no less messy, but it does allow you to handle an
arbitrary number of steps, possibly with arguments, without having to
add another if check as you're doing above. This also lets you know
easilly which step failed:
?
function first($a) { if ($a) return true; else return false; }
function second($a) { if ($a) return true; else return false; }
function third($a) { if ($a) return true; else return false; }
function GrabLock() { echo Grabbing.\n; return true; }
function ReleaseLock() { echo Releasing.\n; return true; }
$ret = true;
$funcs = Array('first','second','third');
$args = Array(1,1,1); // Change one to zero to trigger a failure
if (!GrabLock())
return 0;
while ($ret = $funcs[0]($args[0]))
{
array_shift($funcs);
array_shift($args);
if (!count($funcs)) break;
}

if (count($funcs)) echo Failed at $funcs[0].\n;

Reason is, I pass that $items variable to the following function:

For that, you'll need to open a socket. The function to do this is
usually called PostToHost, and I don't know why it isn't in even the
annoted manual page for fsockopen. A quick google search should turn
up copies of it in all the PHP mailing list archives. But, here's the
version that I use (It's been modified to support both GET and POST):
function sendToHost($host,$method,$path,$data,$useragent=0)
{
// Supply a default method of GET if the one passed was empty
if (empty($method))
$method = 'GET';
$method = strtoupper($method);
$fp = fsockopen($host,80);
if ($method == 'GET')
$path .= '?' . $data;
fputs($fp, "$method $path HTTP/1.1\n");
fputs($fp, "Host: $host\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\n");

if ($method == 'POST')
fputs($fp, $data);
while (!feof($fp))
$buf .= fgets($fp,128);
fclose($fp);
return $buf;
}
$data should be the variables of the query string, minus the question
mark. That is, var1=value1var2=value2, etc. The function doesn't
encode it, so you'll need to do that.

I've looked through the GD library documentation at boutell.com, i've looked through php.net, and every search engine on the internet, and I can't seem to find out what is going on. You're right, the palette only holds 256 colors. The reason for this is that GD was originally written for GIFs only. JPEGs were added on later, and then PNGs were put in as a drop-in replacement for GIFs (Patent issues). But the library was never extended to support high color.

Re: [PHP] returning multiple variables from a function?

What if I wanted to "return" more than one variable from the function? And
how would I assign it a name? Like the actual variable, or is that just not
possible?
I've tried
return $var1,$var2;
You're on the right track.
return Array($var1,$var2);
And when you call the function,
list($ret1,$ret2) = myfunc(); ..or..
$ret = myfunc(); ..and use $ret[0] and $ret[1]
Another option is to pass variables by reference. For example, say you had
a function that returned true or false, but you wanted it to return an error
message with that false. Something like this:
function test($condition,$errormsg)
{
if ($condition == $rightanswer)
{
return true;
}
else
{
$errormsg = "The condition wasn't the right answer.";
return false;
}
}
Then to check it,
if (!test('foo',$error))
echo "Failed test!brError: $errormsgbr";

Re: [PHP] Parsing XML the Sequel :)

The page I want to parse is:
http://213.224.136.110:8080/test.xml

'STORY' = 'nasdaqamex-dot-com',
'STOCK_NAME' = 'issue-name',
'LAST_SALE' = 'last-sale-price',

'NET_CHANGE_PCT' = 'net-change-pct',
'STOCK_URL' = 'issuer-web-site-url');

// handles the attributes for opening tags
// $attrs is a multidimensional array keyed by attribute
// name and having the value of that attribute
function startElement($parser, $name, $attrs=''){

$current_tag = $name;
if ($format = $open_tags[$name]){
switch($name){
case 'STORY':
echo 'New Story: ';
break;
default:
break;
}
}
}
This probably isn't doing what you think it's doing. When the parser
hits a new element tag, it will pass the parser object, element name,
and its attributes to startElement(). $name will be the name of the
element. Equity-quote, issue-name, etc. So when you go to look for
$open_tags[$name], you won't find anything because the array is keyed
to STORY, STOCK_NAME, etc. It looks like you're expecting the array to
be backwards. Switching the keys/values and removing the , /, would
be enough to make it work.

Re: [PHP] multidemention array question(s)
On Fri, 19 Jan 2001, Michael Zornek wrote:
ok so i set up a multidimensional array with the following code:
?PHP
// departments.inc

// This file defines the switches. All the forms, and return displays are

switch number,
// then each department has three proporties.

// 3, Its name.
$departments = array ("s1" = array("On", "On", "The Seybold Report"),
"s2" = array("On", "On", "Publishing Systems"),
"s3" = array("On", "On", "Internet Publishing"),
"s4" = array("On", "On", "The Bulletin"),
"s5" = array("Off", "Off", ""),
(snip)
Now I am creating forms and tables and need to retrieve this info I'd
like to say something like:
if switch s23 is availbe to the admin pages do this, else do that.
if ($departments['s23'][1] == 'On')
// This department can be used in the admin pages
else
// Not
echo switch 34's name
echo $departments['s34'][2]
If you wanted to make the code a bit more intuitive, you could reconstruct
the array to have string keys:
$departments = Array(
's1' = Array('live' = 1, 'admin' = 1, 'name' = "Dept's Name"),
's2' = Array('live' = 0, 'admin' = 1, 'name' = ''),
and so on
);
At this point, you can simply check if a department is live or admin
available with a boolean, and later on people who look at the code won't
have to wonder what the array field $departments['s23'][1] contains.
if ($departments['s23']['admin'])
// This department can be used in the admin pages
else
// Not
echo $departments['s34']['name']

The error tells me that I need a ")" in the line the function call is

do this?
No, you can't do this. Functions within the class can automatically get
to class variables with $this-something, so passing them as parameters
would be somewhat redundant.
class Something
{
var $something;
function Something()
{
$this-something = "More somethings";
}

If you're running Apache/Unix, php_imlib would allow you to manipulate
png's with more than 256 colors.
