[PHP] variable statements
Question: Variable variables and variable functions work great, but how can
you execute arbitrary code statements using php code stored inside
variables?
// Example
function stuff() {
echo 'Stuff';
} // end stuff()
$function = 'stuff';
$function(); // works
/*
Given the above, I would like and had expected the below to be interpreted
by the parser and executed as if it were regular static php code.
*/
// Should interpret: stuff();
$lucid = "stuff()";
$lucid; // doesn't work, but doesn't show an error
// Should interpret: if (1) { echo $function; }
$lucid = "if (1) { echo $function; }";
$lucid; // doesn't work, but doesn't show an error
Thanks for any help,

RE: [PHP] sigh... forms
Speaking of forms, and I'm sure lots have asked this before me, but anyone
know anywhere I can go to see some examples or existing code for
automatically generating and and validating dynamic forms?
Wait though, I'm already doing this myself. To explain further, what I
really want is an abstract set of php functions to say, ok, I want another
form with say 10 questions, and I want to define each question and set of
possible answers (input types and ranges) manually, and have the action
script automatically check that the input types and ranges for each question
are valid.

Why not just make the form's input names "var[]" then PHP will make them
into an array:
for ($i = 1; $i < 100; $i++)
{
if ($var[$i -1] > 0)
echo "Yup. ". $var[$i - 1] ." is greater than 0.";
}

Hey all, I've seen quite a few programs that seem to greatly favor Object Orienting Programming (OOP) in their code. I don't mean to start a holy war or anything of the sort, but as a burgeoning PHP developer, I would like the opinions of my peers. So how about it, ladies and gents? Tell me about the Pros and Cons to OOP, and why you prefer to use it/not use it! Personally, I've always used regular functions to accomplish my repetetive tasks, and OOP seems rather daunting for me, but I'm always open to new (and hopefully, more efficient) ideas! Thanks!

[PHP] Check for Associative Array
What's the best way to check for an Associative Array? There is no
is_assoc() or similiar function listed in the manual (I don't think anyway).
I'm using mysql_fetch_array() and I want to foreach only the assoc. part of
the array without using mysql_fetch_assoc():
foreach ($arr as $key=>$value) {
echo "$key:$value";
}
But of course it show both the indexed array and the assoc array contents.
Is there an existing function to check this, or should I do one of these
things inside the foreach loop:
A) set $last=value and just check if $value = $lastval
B) check if the $key is just a number or just a string
C) $key += 1
?? Thanks,
Henning Sittler

RE: [PHP] Check for Associative Array
Ya, except I want the whole array to exist (index and assoc. array), not
just the assoc. array. So, for the time being, I'll just do this:
foreach ($arr as $key=>$value) {
if ( !is_int($key) ) { echo "$key:$value"; }
}
What is HTH ??
Henning Sittler
www.inscriber.com
Try this:
while($row = mysql_fetch_assoc($result)) {
// code here
}
This way, the resulting array will ONLY be associative.
HTH!

[PHP] php https file download
Hello everyone,
Apache 2.0.40
PHP 4.2.2
Linux
I have a single php script for downloading requested files. It works
beautifully on http over port 80. It does NOT work at all over https on
port 443. I am using the exact same script (the very same file) for both
http and https connections. Apache has the +StdEnvVars enabled for all
files and dirs under the https site. Forms and cookies are working
normally, as are redirect headers. But for some reason, the headers for
file downlaods are not working at all over ssl.
I am really only testing this with IE 6 right now.
What am I missing? What else can I check for?
d.php
function d() {
$fsp = '/mydir/myfile.exe';
$mimetype='application/octect-stream'; $encoding='binary';
//echo basename($fsp).filesize($fsp); return;
//header('Location: https://my.site.com/');
header('Content-Type: '.$mimetype);
header('Content-Length: '.filesize($fsp));
header('Content-Disposition: attachment;
filename="'.basename($fsp).'"');
header('Content-Transfer-Encoding: '.$encoding);
readfile($fsp);
return;
} // end d()
d();
d.php
I call this only after a user clicks a link on a second page. Uncommenting
the line starting with echo out puts the expected basename and filesize.
Uncommenting the line starting with header successfully redirects to the
correct url. Leaving both the above lines commented, the user is prompted
with a open / save dialog but the filename showing is now the script name,
the filesize is missing, and clicking open or save shows a file tansfer
window that does nothing.
I have also tried testing this script with curl on linux. Here's the
output. I noticed the Content-Length header is missing!

Subject: [PHP] Processing Form Data /w $_POST
I have a form (setup.php) that passes values to processSetup.php when they
are written into setup.txt. I'm trying to instead of writing every
idividual value into setup.txt from setup.php, write a loop that will take
as many values as there are in the $_POST array and write them all into a
single array in logical order in setup.txt. I'm new to php and can't figure
out how to do this. I'm thinking of something like...
for ($_POST) {
fwrite($setup, /*something to add current $_POST value to the end of an
array within $setup*/);
}
How should I go about this?
Thank you,

RE: [PHP] Cookies- peanut butter or chocolate??
1. Set a big value in seconds for the time argument 2. Send 2 cookies OR Create one string value containing the two values you want to save, seperated by a a sepcific character of your choice and send this new value as your cookie. Remember to parse the cookie's value when you request it in your script, so that you determine the two seperatevalues actually stored there.

Yes, this question is about PHP cookies. Two questions: 1. How do you setup a cookie that will not expire?? 2. How do you put 2 items that you want to save in the cookie and retrieve??

RE: [PHP] Cannot modify header information - headers already sent
The problem does not appear to be database related, it appears to header
related. You are trying to send header information after sending regular
output. You can't do this:
BUT you can do this:
Try looking at line 29. that's the line where you are trying to output a
header after outputing some text.
