Could anyone please shed some light on the following issue?
I have a problem with including a "test.php" into a "test.shtml" and passing
a variable to the "test.shtml" which should be available and processed in
the "test.php"
the "test.php" document includes the following:
-----------------------------------------------------------
<?php
if ($HTTP_GET_VARS['theValue']) {
print $HTTP_GET_VARS['theValue'];
} else {
print"
<form method=\"GET\" action=\"test.shtml\">
<input type=\"text\" name=\"theValue\" size=\"20\">
<input type=\"submit\" value=\"Submit\" name=\"submit_button\">
</form>
";
}
?>
the "test.shtml" document includes the following:
-------------------------------------------------------------
<html>
<head>
<title>poll</title>
</head>
<body>
<!--#include virtual="test.php" -->
</body>
</html>
I've also tried using the POST method but I got an error stating that post
is not a valid method in shtml.
I have also considered a session variable but since a session needs to
initiated or continued before anything is output to the browser that wont
work (I think).
does anyone have a solution to get this to work?
thanks,
Hans

PHP is starting output buffering automatically for you and then you are

Use ob_get_level to check if output buffering is not already started.
<?php
// start output buffering if it is not already running
if (0 == ob_get_level()) {
ob_start('ob_gzhandler');
}
?>
You may want additional logic that checks to see if the output buffer
hander is ob_gzhandler.

If you figure out how to do this successfully, please share. I'm forced
to use SHTML for my error pages (404.shtml and whatnot), but I'd like to
get those to interact with PHP as well.

POST won't work easily with .shtml files so you are limited to GET and its
length limitations but the following works for me:
//test.php
<?php
if(isset($_SERVER['QUERY_STRING_UNESCAPED'])){
parse_str($_SERVER['QUERY_STRING_UNESCAPED']);
if(!empty($theValue)){
echo 'Value = '.stripslashes($theValue).'<br>';
}
}
print'
<form method="get" action="test.shtml">
<input type="text" name="theValue" size="20">
<input type="submit" value="Submit" name="submit_button">
</form>
';
?>
(parse string seems to like adding slashes)
To use post you will have to post to a .php file to do the processing and
redirect to the .shtml file.

Most any web server will allow you to set a URL as the error handler, so
you can have it as a PHP page. Is there a specific reason why you can't?

I'll check, but I'm pretty sure my host only allows me to edit the
existing *.shtml files to customize my error pages. I don't think it
will allow me to set the error pages to different URL's.

Do you want everyone on the list to send you a message saying they're
not sure what to do?? Just be patient and if someone has an idea,

No, not easily :)
On PHP pages, you could get the referrer, and append it to the URL, forcing
the "correct" REFERRER through to the img script:
<img src="makeMyCounter.php?ref=<?=$_SERVER['HTTP_REFERRER']?>">
And you *could* choose to force .html files through the PHP parser, so
foo.html could use the above code.
I think the other alternative is to use javascript to build the img tag,
because I'm pretty sure JS can figure out the referrer.
But this has the obvious downside of JS being NO WHERE NEAR guaranteed to be
on each browser.
I think i'm missing something though, because I *think* those free
counter/stat programs DO log a referrer... wait -- just checked
thecounter.com, and they DO use JS for the referrer.

Yeah, I had thought about using JavaScript. I had hoped that there was
another way, but if there is, I can't figure it out.

My apologies in advance if this too basic or there's a solution easily
found out there, but after lots of searching, I'm still lost.
I'm trying to build a regexp that would parse user-supplied text and
identify cases where HTML tags are left open or are not properly
matched-e.g., <b> tags without closing </b> tags. This is for a sort of
message board type of application, and I'd like to allow users to use
some HTML, but just would like to check to ensure that no stray tags are
input that would screw up the rest of the page's display. I'm new to
regular expressions, and the one below is as far as I've gotten. If
anyone has any suggestions, they'd be very much appreciated.
Thanks,
Andy
$suspect_tags = "b|i|u|strong|em|font|a|ol|ul|blockquote ";
$pattern = '/<(' . $suspect_tags . '[^>]*>)(.*)(?!<\/\1)/Ui';
if (preg_match($pattern,$_POST['entry'],$matches)) {
//do something to report the unclosed tags
} else {
echo 'Input looks fine. No unmatched tags.';

Letting users enter HTML is a bad idea. Even if you only let them use
<b> tags, they can still put ONCLICK and mouseover effects for the bold
text to screw with your other users.
Use a BB style code, such as [b] for bold, [i] for italics, etc. This
way, you only match pairs and replace them with HTML and use
htmlentities on anything else. This way an unmatched [b] tag won't be
replaced with <b> and mess up your code.

Hi,
I don't believe you can create a regular expression to look for something
that's NOT there.
I'd take this approach (tested with drawbacks, see below):
function check_tags($text) {
$suspect_tags = "b|i|u|strong|em|font|a|ol|ul|blockquote";
$re_find = '/<\s*(' . $suspect_tags . ').*?>(.*)/is';
while (preg_match($re_find,$text,$matches)) {
// a suspect tag was found, check if closed
$suspect = $matches[1];
$text = $matches[2];
$re_close = '/<\s*\/\s*' . $suspect . '\s*?>(.*)/is';
if (preg_match($re_close, $text, $matches)) {
// fine, found matching closer, continue loop
$text = $matches[1];
}
else {
// not closed - return to report it
return $suspect;
}
}
return null;
}
$text = <<<EOT
This text contains < font
size=+4 > an
unclosed suspect </fint>tag.
EOT;
$tag = check_tags($text);
if ($tag) echo "Unmatched: \"$tag\"\n";
else echo "Perfect!\n";
The drawbacks: This approach is softly targeted at unintended typos, such
as in the example text. It won't catch deliberate attacks, such as
Blindtext <font color="red><font size=+22>Hehe I've got you</font>
because it is missing the second font opener. To catch these attacks you'd
need to build a source tree of the text in question.
HTH,

Let's say I need to take one of 20 actions depending on a form selection. I
could use a switch statement with 20 cases, but I could also do something
like:
// Pretend this comes from a form
$formchoice = "mars";
$response = array(
"mars" => "go_mars()",
"mercury" => "go_mercury()",
"earth" => "go_earth()");
foreach ($response as $choice => $action)
{
if (strtoupper($formchoice) == strtoupper($choice))
{
eval("$action;");
}
}
But are there even better ways?

I'm just pulling this out of my ear, but assuming the structure you gave
what about a simple
eval("$response[$formchoice];") ;
to match if it matches and do nothing if it doesn't? In fact, I got
curious, so here is some test code I just whipped up; note that when the
choice is 'comet' nothing happens.
function go_mars()
{ print "Welcome to mars, dude!\n" ; }
$formchoice = "comet" ;
$response = array
(
"mars" => "go_mars()" ,
"mercury" => "go_mercury()" ,
// continue ad nauseam
) ;
print "Will we eval?\n" ;
eval ("$response[$formchoice];") ;
print "DONE!\n" ;
Seems like this ought to be pretty safe since you're writing the go_*
functions and otherwise nothing matches and you eval a "".

$formchoice = "mars";
go_planet ($formchoice);
Keep the high-levels of the script as simple as possible, push the
complexity down into functions where it's hidden from view.
Maybe go_planet() just calls go_mercury(), go_venus(), etc., or, more
likely, there's enough shared-functionality for only go_planet() to be
necessary.
Either way, you've replaced 11 lines in the main body of your script
with 1 line, and the next person to deal with your code will be
grateful.
[An OO programmer would probably create a planet object...
myPlanet = new Planet()
myPlanet.setType($formchoice)
or something, with the same end (hiding complexity) in mind.]

You know you can use a variable as the name of a function??
So, if you had the functions mars(), mercury() and venus(), and you had
$formchoice = 'mars';
You can just call
$formchoice();
and it'll be just like calling mars(). It works the same for the other
functions. You'll still want to validate it so you know it's calling on
of the functions you want called. A simple array with valid planets and
a call to in_array will solve that.

:) I think if You use go_planet($choice), the problem will still remain,
bacause that "big switch" should reside in go_planet() func, so we come to
the start of the problem. (of course if we should take different actions
depending on the choice).
I think the one way is like described in upper message, to use variable
names of functions. Ok, that's nice, but I personally wouldnt use this as it
is very language specific (of course we could regard it like pointers to
funcs in C :)), and I think doing many such tricks of this increases the
complexity of your code and so on.
I'd use OO principals for that, making an object for each planet, and each
shoud have a method like go_planet() for THIS particular planet, as they all
this objects would inplement the interface with the same method (of course u
may not do that inheritance in PHP explicitely), So u'd have smth like this:
$response = array(
> > "mars" => object, //mars object
> > "mercury" => object, //mercury object
> > "earth" => " object, //earthobject
and if your choice is "mars", u'd call $response['mars']->go_planet();
Its a known OO principal for avoiding switch'es and if's, and PHP is a nice
OO style language, so doing in OO like this should give valuable practice
for migrating to any other "real" OO language.
Sorry, if wrong,
Mark.

For help with getting MSSQL to work with php, check the comments for

Some thoughts on variables and constants:
a) You can't redefine a constant but can redefine
a variable.
b) Constants are autoglobal (like superglobals) so
for example:
<?php
define ('CONSTANT', 'some value');
$variable = 'some value';
function foo() {
global $variable;
print $variable;
print CONSTANT;
}
foo();
?>
Had we not used global $variable, the $variable
would not have been available inside the function.
But, the constant is AUTOglobal so it is. Read:
Variable Scope:
http://www.php.net/variables.scope
c) Constants must be scalar values in PHP4, (so
not arrays, objects, or resources).
d) Constants are cool, variables are cool too.

Philip Olson

See the flash docs. There are ways of making javascript and flash interact.
So make a dynamically generated javascript which will pass variable to

One other thing you could do is simply set up SSL with your own certificate
so that it will encrypt the connection and then run code via JAVA or some
other client side applet that will get the MAC address from the client
machine directly. You can then check the MAC against the addresses allowed.
Since the connection is encrypted nobody knows that that is what you are
checking. Of course there is still a potential for someone that you
previously allowed access to find out how you are identifying them and use
it against you later on, but there are also problems with identifying
someone by their computer unless they keep the computer locked in a closet
while they are away. I guess it depends on what you are protecting.
National secrets etc. By the way, open SSL with self signed certs is a free
method but it is not a good idea if you are needing to verify your
credentials to the person coming in.

Yeah I'm not super concerned about security and such, this is only a
personal page so something simple will do the job. I think I'll just
end up hacking together my own encryption algorithm and then storing
encrypted passwords in a cookie.
Hehe. Security through obscurity, everyones favorite way :)

Like I said, it's a probability thing. Garbage collection has a 1%
chance of being iniated. It may take two hours for that 1% chance to hit
and clean up any data that's over 1440 seconds old. Other times, it may
hit it a couple times in a row quickly, so you lose your data very close
to 1440 seconds.

Garbage collection is only triggered in the directory identified by
session.save_path, whatever it is. If you change it to something else in
your code, it's not affected by garbage collection.

I remember asking about this a while ago. There were no answers. I don't
think there's any way for PHP to monitor it. Some web servers will store
the total amount of memory your script took up. So if you parse those
logs you may get the info you need.

Hello,
I want to set a cookie when I enter a text into the text field, and it
shows the text I submitted immediately, thus I write a sample php code like
this:
<?php
if (isset($HTTP_POST_VARS['Name'])) {
setcookie("name", $HTTP_POST_VARS['Name'], time()+86400*10);
}
echo $name;
?>
(I set the text field is Name and the data will be sent to another page)
In another page, I insert <?php echo $HTTP_COOKIE_VARS['name']; ?> in the
beginning of the code.
Is the code right?
Then I run the test, I enter a name into the text field and submit it. But
it shows "Notice: Undefined index: name in ..", it can't show the name I
submitted.
Why?Anything wrong??
Thanks!!

Hi all -
While I know that this is not possible with PHP alone,
Does anyone know how to capture website screen shots
using PHP. I have recieved many spam mails featuring a
screen shot of our company website and I imagine that
it would be quite possible combined with some sort of
web browser.
It would be great for a couple projects I'm working on
to use this in the same style as alexa.com. (featuring
screenshots next to search results.).
thanks for any info!

I doubt PHP will have anything to do with it... My guess is there MUST be
some form of automation/macro tool available on Windows or Linux, which
enables you to load a URL in a browser, and take a screen shot. I get the
feeling it could also be done with AppleScript on the Mac.
Afterall, PHP, Perl, etc aren't a browser. But it's possible that PHP can
trigger a command-line program to do the above.

Hi,
I'm doing a small project at work with php, ms sql server on w2k IIS5.
All the data access is done through stored procedures. This seems to
be working fine, the record sets are returned and the stored
procedures execute without error however I can't get any return
values from them.
For example I have the following php code:
// setup stored procedure
$sp = mssql_init("spGetReseller", $conObj);
mssql_bind($sp, "@ResellerID", $loginID, SQLINT4, FALSE);
mssql_bind($sp, "@ReturnCode", &$retVal, SQLINT4, TRUE);
$rs = mssql_execute($sp);
So the @ReturnCode variable is defined as OUTPUT in the SP and I am
passing in $retVal by reference. This is my stored procedure.
ALTER PROCEDURE spGetReseller
@ResellerID int
, @ReturnCode int OUTPUT
AS
SELECT Something
FROM SomeTable
WHERE SomeField = 1
-- set return code
IF @@ROWCOUNT > 0
SET @ReturnCode = 0
ELSE
SET @ReturnCode = 1
This should set the returncode to be 1 if there are no rows returned.
However no matter what, it will never get this returncode from the
stored procedure. (ie $retVal will not be changed by the mssql_bind
function) I ran the stored procedure and the @returnCode variable is
set correctly there so that isn't the problem.
Does anyone know what could be the problem there? I guess I could
return @ReturnCode in the recordset but that would be kinda hokey.
Thanks,
Leo

Hi, all --
How can I tell if a directory is writable? It seems that is_writable
only works on file, and the mode I get out of stat() is [in this case,
anyway] '16895' for a 0777 dir.
TIA & HAND
:-D

I ran into something interesting & the only thing I can figure out is that
functions won't use any variables other than globals, those past to the
function, or those created inside the function?
here's what I had that didn't print anything other than 3 blank lines for
this section of code -
$byteSize[0] = "bytes";
$byteSize[1] = "kb";
$byteSize[2] = "mb";
function getMaxSize( $maxSize )
{
echo $byteSize[0] . "<br/>\n";
echo $byteSize[1] . "<br/>\n";
echo $byteSize[2] . "<br/>\n";
....
}
but, if I put the array inside the function it would actually work -
function getMaxSize( $maxSize )
{
$byteSize[0] = "bytes";
$byteSize[1] = "kb";
$byteSize[2] = "mb";
echo $byteSize[0] . "<br/>\n";
echo $byteSize[1] . "<br/>\n";
echo $byteSize[2] . "<br/>\n";
....
}
what's up with this? Maybe I'm just up way to late again.

if you declare $bytesize global within the function it will work:
function getMaxSize( $maxSize )
{
global $bytesize;
echo $byteSize[0] . "<br/>\n";
}
You'd be still better off passing the array as variable:
function getMaxSize( $bytesize, $maxSize )
{
echo $byteSize[0] . "<br/>\n";
}
And lastly, for performance issues, pass it as a reference:
function getMaxSize( &$bytesize, $maxSize )
{
echo $byteSize[0] . "<br/>\n";
}
Without a reference, the array is copied to the function. By passing a
reference the function is working on the original array, no copy overhead.
Note: When passed as reference, any modification on the array within the
function will effect the original array (same is true if declared global).
Without reference the original array remains unchanged.
