Hello,
Here I've got a few related questions, which are not stated explicitly
in the manual.
1. The manual says that the magic_quotes_gpc setting cannot be set at
runtime. Is it not possible to set this setting in an ini file, and
parse it with the parse_ini_file() function? Also, if this was
possible, what will PHP do to the modified variables? Run the
stripslashes() functions on all of them?
2. On a related line, are we allowed to use ini values in our ini file
that contradict the defined ini values in php.ini? Won't this confuse
the parser?
3. What would I do if I didn't have access to my own custom ini file,
but could somehow get the file either by using fopen(), file() or
file_get_contents()? Can I parse a string (or array) like an ini
file?
4. Does parse_ini_file() allow us to specify absolute filenames of the
form "scheme://..." from another server, if our allow_url_fopen
is TRUE?
Thank You.

Hi
I am trying to find examples of how and where to use $_POST, $_GET etc. I
searched a lot of places, but cant seem to find decent examples or a
tutorial or something.
Can someone point me in the right direction?

$_POST and $_GET are associative arrays containing the form data sent by a
user to a page. Whether your user's submitted form data is in $_POST or
$_GET depends on what method attribute you've specified in the <form> tag in
your HTML code. Take a look at the following HTML example:
<form method="get" action="script.php">
<input type="text" name="firstName">
<input type="text" name="lastName">
<input type="submit">
</form>
Now in the file script.php you can access the submitted form values in the
$_GET array, using the form field names as array keys. e.g:
<?php
$firstName = $_GET['firstName'];
$lastName = $_GET['lastName'];
echo 'The user submitted the name'.$firstName.' '.$lastName;
?>
If you had set the <form method="post"> in your HTML, then you could have
accessed the form values from the $_POST array within PHP.
Hope that helps,
Al

Why would i do this long coding in the second page "script.php" the
variables values is already available in "script.php" when i do a post or
get, if i use $_POST or $_GET to define a variable already available, that
seems like a lot of extra coding for no reason.

Let's make some assumptions -
1) having register_globals on is bad
2) we all like to write scripts as secure as possible
Given #1 and #2, if you stop referencing variables directly (e.g. as
$firstName in the script below) since register_globals is off, it
immediately adds a degree of security to your script if you're aware of the
difference between GET and POST requests. GET requests are quite easy to
fake (just add the variables and values to the URL) and unless you have
checks against it, a malicious user could take advantage of this. POST
requests are a bit more tricky to fake, but not "difficult" in the grand
scheme of things.
Either way, in the examples that Piet wrote, there's no "extra coding".
Writing the variable names is a bit more key strokes, but given the
advantages of having even a slightly more secure script, it's a good thing
and worth a bit more typing.

Okay, for everyone took a break for Christmas, and to update Jasper and
Jeremy--who've tried big-time to help me--here's again the sitch and where
I stand as of now.
I'm on a Macintosh PowerBook running OS X.2.1 and PHP 4.3.0. I'm tryning to
run the following code:
<html>
<head>
<title>
persistence demo
</title>
</head>
<body>
<h1>Persistence Demo</h1>
<form>
<?php
//increment the counters
$txtBoxCounter++;
$hdnCounter++;
print <<<HERE
<input type = "text"
name = "txtBoxCounter"
value = "$txtBoxCounter">
<input type = "hidden"
name = "hdnCounter"
value = "$hdnCounter">
<h3>The hidden value is $hdnCounter</h3>
<input type = "submit"
value = "click to increment counters">
HERE;
?>
</form>
</body>
</html>
What that gets me is:
Parse error: parse error, unexpected $ in [my path to this file] on line 33
register_globals is, of course, off. So I add $txtBoxCounter =
$_POST['txtBoxCounter] and $hdnCounter = $_POST['hdnCounter] as separate
line right after <?php. And that gets me an unexpected TVARIABLE message.
Anyone, please?
Thank you.

Change:
$txtBoxCounter = $_POST['txtBoxCounter]
$hdnCounter = $_POST['hdnCounter]
to
$txtBoxCounter = $_POST['txtBoxCounter'];
$hdnCounter = $_POST['hdnCounter'];
(Notice the ' at the end of txtBoxCounter and hdnCounter.

I am new to php.
My site, at the moment, uses SSI to call a Perl browser-sniffing script.
I would like to:
1. use php to call the Perl script.
2. then save the values the Perl script outputs as php variables.
Can this be done? If so, how?
Thanks,
Philip Pawley
