Re: [PHP] Incrementing counter from an HTML page.
Suggestions: 1. use a picture for the counter (with the image - handling library) 2. use a javascript script :)
[PHP] Restricted access
Hi All, I want to give access to resources (PDFs and some RTFs) only to registered users and I also want to deny that kind of access to people that "guess" the URL. I guess it is all about putting these files outside the web-tree and somehow putting PHP to work. Could you enlighten me ? :)) -- Thnx, Cip -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Bug ?

Re[2]: [PHP] Bug ?
David, thank you very much. I suspected smth. like this, but still, it is
weird: PHP already has the "&" operator (?) for assigning by reference. And
there is more: I noticed that if I use the "sort" function instead of
"array_multisort", it works as expected.
I still think there is a bug involved :(
>>I tried something like this:
>>
>>>$arrayA = array(5,4,3,2,1);
>>$arrayB = $arrayA;
>>array_multisort($arrayA);
>>echo $arrayA[0], "";
>>echo $arrayB[0];
>>?>
>>

>>The output is:
>>1

>>I think it should be:

>>5
DO> It's not a bug (ie this is expected behaviour in PHP4 for various

DO> The way to think of it is that $arrayA doesn't actually contain your

DO> To add insult to injury, some array operations can implicitly cause a

DO> function echo_array($a) {
DO> foreach ($a as $v) {
DO> echo ($v);

DO> echo ("");
DO> }
DO> $arrayA = array(5,4,3,2,1);
DO> $arrayB = $arrayA;
DO> $arrayA[] = 6; // this line added
DO> array_multisort($arrayA);
DO> echo_array($arrayA);
DO> echo_array($arrayB);
?>>

[PHP] unset() un-appropriate ?
I have a form with 3 checkboxes x1,x2,x3. I want to build an array of
values from the checked boxes; I choosed the following approach:
1. build an array with all values
2. eliminate from array the "" values using unset
CODE:
$x = array($_POST['x1'],$_POST['x2'],$_POST['x3']);
do {
for ($i=0;$i < sizeof($x);$i++) {
$stop = 0;
if (!trim($x[$i])) {
$stop = 1;
unset($x[$i]);
break;
}
}
}
while ($stop>0);
For some reason, the code doesn't work (loops ad infinitum). But replacing
unset($x[$i]);
with
array_splice($indice, $i, 1);
it does.
Help!

[PHP] Playing with globals
Hi All, My system: Windows NT 5.0 build 2195 / Apache/1.3.23 - PHP 4.1.1 Here is a nice snippet: ___ __ the result: 1 (however, I expected to see "2") If I change to: ___ the result: 2 I understand the concept o local and global variables, but isn't $GLOBALS supposed to work as an alternative to "global" statement ? -- Best regards, Ciprian > Teamwork is essential.
