Re: [PHP] Pass a relative path [with slashes] into a 'clean' url
Assuming you mean URLs as GET variable values, urlencode() and urldecode()
might be the ticket:

What is a good/accepted way to pass a relative or absolute path

I could replace the relative url's slashes with another character,
but would love to know a cleaner less confusing way...if it exists
example url:
http://localhost/testscript/../image.png/jpeg/42/0/
example php:
list($dummy,$relative_path,$type, $color, $cache) = explode('/',
$_SERVER['PATH_INFO']);
where:
$relative_path=../image.png
$type=jpeg
$color=42
$cache=0

Re: [PHP] Splitting a string
Assuming var1 and var2 only ever use the last four numbers (untested): $length = strlen($number); // get string length $var1 = substr($number,0,$length-4); // get number until only 4 numbers are left $var2 = substr($number,$length-4,2); // get 3rd and 4th last numbers. $var3 = substr($number,$length-2,2); // get last two numbers.

I've been using substr with negative numbers to fetch the last two vars. thereafter explode to get the first number. Ok I understand the code and can use it, but it feels wrong.

Re: [PHP] move_uploaded_file and CPU wait state (IO)
Are you sure its the move_uploaded_file() function that is causing the delay? It could be the actual upload of the file itself. If it is the function causing the delay than try the rename() function instead. Also, I have used the copy() and unlink() functions and they work fast.

Try simplifying the problem to determine the error point. For example don't involve $_POST just try setting a cookie with hard coded variables.

Re: [PHP] Set variable outside of scope (redo)
Generally, scope is fairly loose in PHP. If $row is set by
mysql_fetch_array(...) it should carry throughout your script as it is,
unless modified. Try commenting out non-relavant pieces of the code and
var_dump(...)ing the $row variable at the start and throughout the script.

Re: [PHP] One big file or many includes?
I don't know about whats best for the compiler (rather interpreter), but if it is a really big site with a lot of access, transaction and management functionality I recommend you start breaking the code into classes and separating each class into a file and documenting... A LOT! It will be clearer to understand and maintain. IMHO.

Re: [PHP] Post-Vars doubled / corrupted
Hi Sabine,
Its been my experience that you need square brackets after the input
checkbox name for PHP to see an array. This page discusses that:
http://www.evolt.org/article/Storing_form_array_data_to_MySQL_using_PHP/18/60222/
Change your code to the following and give it a try.
ul id=colors
liinput name=colors[] id=id1 type=checkbox value=1
/label for=id1red/label/li
liinput name=colors[] id=id2 type=checkbox value=2
/label for=id2blue/label/li
/ul

liinput name=colors id=id2 type=checkbox value=2

to your minimalistic script.
Checked both and got
Array ( [colors] = Array ( [0] = 1 [1] = 2 [2] = 2 ) [testvar] =

for post.
I don't really think it's a problem of my code.
Perhaps a problem of the servers configuration. But I'm not really
familiar with installation and configuration duties. So I don't know
where to search.
But meanwhile I read something about input filters in Apache 2.
And thought if there is a filter on this server which corruptes my post
vars?
Config is (I don't know which parameters are really importend):
[IHOST_VERSION]= Linux-1.0
[SERVER_SOFTWARE]= Apache/2.0.55
[SERVER_PROTOCOL]= HTTP/1.1
PHP 4.3.11
Server API Apache 2.0 Filter
I searched for information if PHP 4.3.11 is supposed to work fine with
Apache 2.0.55, but didn't find a clear answer.
Perhaps you know (or someone else knows) if my thoughts are going in the
right direction?

$imageArr = array();
// Create array with $imagesNeeded number of elements.
for($i=0;$i$imagesNeeded;$i++) {
// choose image
$tmpImg = $openFile[array_rand($openFile)];
// Keep getting images until the image you have is not in the existing

while(in_array($tmpImg,$imagesArr)) {
// choose image
$tmpImg = $openFile[array_rand($openFile)];

// Put unique image into array
