I looked through your configuration files and didn't notice any serious differences between them and my ones. I have PHP 4.2.1/Apache 2.0.36 on WinXP Pro. My register_globals was off. When I made it On your scipt worked properly. I don't know what the reason. What PHP you have?
I attached my php.ini. Maybe you can find some important things. Another one question: does $PHP_SELF give proper value? It must not be set if register_globals=off. So if $PHP_SELF is set to some value, then global variables are registered.
And the last question: why do you use global variables? It's much easier to use superglobal arrays $_POST, $_SERVER, etc. They guarantee that any values passed to your script won't be mixed.

I'ld like to know if there is any possibility to distinguish the selects if I've multiple multiple selects, that is, more than one on the same page? What I'm loooking for is the possibility to have an unknown number of multiple selects on the same page....
Is it possible? Anyone who can describe how to do this or provide a link to some tutorial? And also, where in the manual can I read about this?

Just give each select its own name. Or name them all the same followed by an [] and you'll end up with a multi-dimensional array if things go right...

Sounds better - but I've a lot of items and I'ld like to know which of the arrays that go to which item... Can I just write …name=array[whateverid] and then in some way reveal the whateverid's?

Ok, I can't get this right...
Have the following code:
<?
$choices = array(1 => 'dog', 2 => 'cat', 3 => 'mouse', 4 => 'frog');
if (is_array($_REQUEST['animals'])) { // get the number of selectcases echo "get the number of selectcases: " . count($animals) . "<br>"; // get the number of provided selects from select with name "2" echo "get the number of provided selects from select with name \"2\": " . count($animals[2]) .

"<br>"; } ?> <form method="post" action="<?= $_SERVER['PHP_SELF'] ?>"> <select multiple name="animals[2]"> <option value='1'>dog</option> <option value='2'>cat</option> <option value='3'>mouse</option> <option value='4'>frog</option> </select>
<select multiple name="animals[4]"> <option value='1'>dog</option> <option value='2'>cat</option> <option value='3'>mouse</option> <option value='4'>frog</option> </select> <input type="submit"></form>
Why does it not work?
// get the number of selectcases echo "get the number of selectcases: " . count($animals) . "<br>";
This works great // get the number of provided selects from select with name "2" echo "get the number of provided selects from select with name \"2\": " . count($animals[2]) . "<br>";
But this doesn't...

but the scriptname itself will be included there. Try this, if you don't want the scriptname to be included.:
$url = preg_replace('/^(http:\/\/)[^\/]+((\/[^\/])*\/)([^\/]+)$/', '\\1$SERVER_NAME\\2', $SCRIPT_URI);
Haven't tested them, but should work.

If you're getting this discouraged over creating a URL, then maybe you should give this stuff up. There's no variable that gives you the full URL of your script, deal with it.
What is this parse() function you're using? What does it do? Why is this "over kill and BS"?
Try this:
$myurlvar = http:// . $SERVER_NAME . dirname($SCRIPT_NAME);

A couple of simple ones here ... the usual references don't appear to give a straightforward answer on these:
Can arrays be passed to functions just like a simple variable?
Can arrays be passed as values in hidden form fields just like a simple variable?
I've been playing around with these and getting inconsistent results. I've been trying things like serialize and urlencode, but still haven't worked out a straightforward 'rule' or policy.
Can someone throw some light on this?
TIA Michael
attached mail follows:
> Can arrays be passed to functions just like a simple variable? yes, no difference. You can pass every variable to a function, you can pass constants or your values directly. You have to use a variable if a function requires passing by reference or if you want to pass by refernce, because only variables can take the value back.
> Can arrays be passed as values in hidden form fields just like a > simple variable?
yes, but differently. either you serialize the array, send it urlencoded to the page and unserialze it there: //page1.php: <?php $array = array(1,2,3,4,5); $array = urlencode(serialize($array)); ?> <a href="page2.php?array=<?php echo $array; ?>">Page2</a> //or input field: <input type="hidden" name="array" value="<?php echo $array; ?>">
//page2.php <?php $array = unserialize($array); print_r($array); ?>
or you can appen urls like this, no serialization or sth needed then both pages: numerical indexed arrays: <a href="page2.php?array[]=1&array[]=2&array[]=3&array[]=4&array[]=5">Page2</a> or <a href="page2.php?array[0]=1&array[1]=2&array[2]=3&array[3]=4&array[4]=5">Page 2</a> string indexed arrays: <a href="page2.php?array[test1]=1&array[test2]=2&array[test3]=3&array[test4]=4& array[test5]=5">Page2</a>
or with forms:
numerical indexed arrays: <input type="hidden" name="array[]" value="1"> <input type="hidden" name="array[]" value="2"> <input type="hidden" name="array[]" value="3"> <input type="hidden" name="array[]" value="4"> <input type="hidden" name="array[]" value="5"> or <input type="hidden" name="array[0]" value="1"> <input type="hidden" name="array[2]" value="2"> <input type="hidden" name="array[3]" value="3"> <input type="hidden" name="array[4]" value="4"> <input type="hidden" name="array[5]" value="5"> string indexed arrays: <input type="hidden" name="array[test1]" value="1"> <input type="hidden" name="array[test2]" value="2"> <input type="hidden" name="array[test3]" value="3"> <input type="hidden" name="array[test4]" value="4"> <input type="hidden" name="array[test5]" value="5">

Yes.

Yes, with a little work.

For example:
$arr = array('color' => 'red', 'fruit' => 'apple');
$str_arr = urlencode(serialize($arr));
<input type="hidden" name="foo" value="<?php echo $str_arr ?>">
And in the action script, do:
$arr = unserialize(stripslashes($_REQUEST['foo']));
Notes:
a) stripslashes may be needed, in case magical quotes get in the way (magic_quotes_gpc). b) am using $_REQUEST, you may use $_GET or $_POST or whatever contains the form value. c) hidden, text, textarea ... doesn't matter. d) a way to test if what _should_ be an array is really an array is with print_r() and/or is_array(). print_r($arr); e) we don't need urldecode() because that'll happen automatically when going through the form. f) you could use implode() instead of serialize too.

Just to be clear, $_GET['id'] will work fine with register_globals on or off. In otherwords, these php predefined variables will exist either way. Just like the older non-super ones, such as $HTTP_GET_VARS.

This is not really specific to PHP (although the information might be useful for all that form validation we all do), and for that I apologize in advance (does anyone know of a regex mailing list?), but maybe someone here can help with the following:

None that I have seen take into account the fact that, although dashes ("-") and dots (".") are allowed in a domain name, the domain name can neither begin with nor end with a dash or dot, and additionally, two dashes or two dots in a row are not allowed and a dash followed by a dot or a dot followed by a dash are not allowed.
So, I've come up with two regex's for checking domain names. The first one checks that the name contains alphanumerics, the dash and the dot, and neither begins with or ends with a dash or dot:
^[a-z0-9]$|^[a-z0-9]+[a-z0-9.-]*[a-z0-9]+$
The second one checks that two dashes and two dots are not together and that a dash followed by a dot or a dot followed by a dash are not together:
--|\.\.|-\.|\.-
Putting it all together, the way I check for a valid domain name is with the following:
if (eregi("^[a-z0-9]$|^[a-z0-9]+[a-z0-9.-]*[a-z0-9]+$", $domain_name) != true OR eregi("--|\.\.|-\.|\.-", $domain_name) == true { error; }
So, my question (finally!) is this:
Is there any way to combine both expressions (basically, one part that checks for false and one part that checks for true) into one regex that just returns true or false? I haven't been able to find any documentation that shows me how to do that, basically a "like this but not like this" syntax.
BTW, anticipating someone mentioning the fact that the above regex's don't check for a domain name ending with a dot followed by three characters max (as in .com, .net, etc.), it's because that long-held truth is no longer true. We now have .info and .museum, and who know what the future will bring.
About the only truth left is that domain names end in a dot followed by two characters minimum (there are the country code domains like .us, .de. etc. but there are no one character TLD's at present and I would expect perhaps not for a long long time, but you never know). Perhaps someone would expand on the regex above to include checking for a name ending with a dot followed by two characters minimum, I just haven't been into regex's long enough to know how).
Of course, you could get really anal about all this and check for domain names that only end in the current ICANN root server TLD's (about 260 or so, I believe), but that wouldn't account for TLD's that operate within other root servers (there's always sumthin'). Anyways,
Any help with the above is certainly appreciated!
Jeff
attached mail follows:
I use this, but it's a preg rather than ereg pattern:
'/([a-z0-9]+[a-z0-9\-]*\.)+[a-z0-9]+[a-z0-9\-]*[a-z0-9]+$/i'
Two problems (which in practice are so slight that I've foregone my usual standards-analness to ignore them)
1) It will allow a domain name component (except the final one) to end with a dash (e.g., "test-.example.com").
2) It will not allow a one-character final component.

Dear folks,
Has anyone ever been able to get a CGI to produce valid PHP output??
Whatever I do, my browser ALWAYS wants to open or save the non-parsed PHP text produced by the CGI file. And yes, I have set the proper ExecCGI and PHP entries in my vhosts.conf; and yes, I restarted the server.
Basically, I open an existing php file (in a Perl CGI), and output its contents again to the Apache server. The CGI starts with sending this header:
print "Content-type: application/x-httpd-php\n\n";
Then I output the text. But, no matter what I do, it will not parse the PHP code. I do not understand this. Regular PHP files in that dir work fine. There is, as far as I can see, no reason why this should not work.
And the PHP file really needs to be generated from the CGI, as it needs to run as a specific user.
Anyway, any help would be much appreciated,
- Mark

The problem is that you are sending this output to the browser and not the server. You can do this with XML because IE and Netscape have XML parsers built-in. You should create a form that will catch the data from CGI then handle it on the server. There might be other work arounds as well...however, I have only played with the XML stuff...
Thanks,

I tested ini_set('register_globals',0) and ini_set('register_globals','Off') for turning register_globals off. It doesn't work and it doesn't produce any notice, warning or error.
Here's a quick example:
<?php
ini_set('register_globals',0);
if(isset($test)) echo "<h2>$test</h2>";
?> <form action="ini_set.php" method="get"> <input type="text" name="test" /> <input type="submit" /> </form>
This prints out $test, what it shouldn't do with register_globals turned off. I tested this with PHP 4.1.2 and 4.2.1. Even if I start to doubt it is supposed to work according to the documentation. Can anyone tell me what I've done wrong?
For some strange reason if I do
echo ini_set('register_globals',0);
it will print "10". For
echo ini_set('register_globals','Off');
it will print "1Off".

PS: ini_set works fine with include_path and error_reporting

Rite, when you see a web form, you know you can simulate the submit by filling in the values in the address field, just like a GET method, and it usually works the exact same. But how do you do it when one of the fields in the form is a file upload?!?!?!
For the record, its a GIF file you've to upload. Is there any way to do this in PHP??
attached mail follows:
<?PHP $im = createfrombmp("image"); print "<FORM METHOD=\"post\" ACTION=\"actionpage.php\">"; print "<INPUT TYPE=\"hidden\" NAME=\"image\" VALUE=\"$im\">"; ?> you get the idea
I think PHP does have other funtions for file uplading though.
