Can we see some sample data? An example of what $variable and $constant

A quick glance at the code I'd have:
if (isset($variable)
{
if ($variable $contstant)
{
stuff
}
elseif ($variable $constant)
{
more stuff

else
{
other stuff

We do not like too much the idea of the password being in clear text.
Example
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
'mysql_password' should be encrypted
Why? It's not going to offer any protection. If I know your encrypted
password and am able to access your database using it there is no reason
for me to know what your cleartext password is. In other words if I am
able to read the file containing your password (whether encrypted or
cleartext) then I can access your database.

RE: [PHP] File Locking during *other* file operations
No really good reason that I can think of. I don't see any reason as to
why it wouldn't work with just 'x'.
Must have been having a 'beer' moment.
yes, it should probably clear out stale lock files but the files I
protect with this are better left untouched if the lock fails. I think
that locks fail for a reason and you should find that reason before you
unlock and potentially break something.

How come you use wx up there, and just 'x' here?
Is there some reason for that?
One may (or may not) want to consider a mechanism for throwing out
really old lock files, since it's possible your PHP script or
application would eventually fail to remove a lock file... Or not,
depending on how you code the rest of it.

In earlier versions of PHP, you could use the $HOSTNAME global

However, that variable is no longer working and I can't seem to find

How can you get the server/machine name?
$_SERVER['HTTP_HOST']
$_SERVER['SERVER_NAME']
Interesting. When I do:
print_r( $_SERVER )
both of the above print out the site name and not the host name. For
example, the site name is 'mysite.mydomain.com'
and the servername is 'machinebob'. Each of the above print out
'mysite.mydomain.com' and not 'machinebob', which is what I was
expecting.

RE: [PHP] How can I fix that
I've just had this exact problem. The solution as far as I found is one of the following: 1. Keep a $_SESSION going and set a flag, then on a re-post you can check the flag to see if it's set and hopefully spot the re-post. 2. Check to see if what you're about to enter is already there, chances are it's a repost - this only works for certain sorts of applications though. 3. Divert the user to a different page using header() so that if they hit refresh they only refresh the thankyou page and not the post - this doesn't stop 'back' for screwing things though. 4. Use java to prevent the history, I've found this example (not tested it) script language=php history.forward(); /script Hope this helps Matthew -Original Message- From: Aalee [mailto:[EMAIL PROTECTED] Sent: 13 December 2004 09:50 To: [EMAIL PROTECTED] Subject: [PHP] How can I fix that Hi there everyone...

[PHP] Referencing Multi Dimensional Arrays
Hi, I've kind of solved this question already using recursion but I recon (in the grand tradition) that someone has a better solution! I have an multi dimensional array that is of variable depth, a snippet is shown below. The problem is that I don't know how deep the array goes as any entry can contain further entries which can contain further entries and as the array grows the data is increasingly unknown. My first thought was to use variable variables but the following doesn't work: $Network = array(--as-below--); $MyKey = [allocations][network][0]; print $Network[$$MyKey]; Now the obvious use of print $Network[$$key1][$$key2]; won't work for me as sometimes I need to be two layers deep and other times five. As I mentioned I've solved this problem using recursive functions but it's all a bit nasty. I've knicked various functions from the php site to search multi-dimensional arrays and can return myself an array of keys leading to the item I'm after but I can't seem to use that array to reference the data! All/any solutions or pointers (no pun intended) welcome. Kind regards Matthew Array ( [allocations] = Array ( [network] = Array ( [0] = Array ( [address] = 10.0.0.0 [netbits] = 8 [name] = TEST [creationdate] = 20041124 [description] = Test Address Space [security] = Array ( [alloc] = intech [subnet] = intech [unalloc] = intech ) [free] = Array ( [0] = Array ( [netbits] = 9 [address] = 10.128.0.0 [creationdate] = 20041125 ) [1] = Array ( [netbits] = 10 [address] = 10.64.0.0 [creationdate] = 20041125 ) ) [network] = Array ( [0] = Array ( [address] = 10.0.0.0 [netbits] = 24 [name] = MAFFNET [creationdate] = 20041125 [security] = Array ( [alloc] = intech [subnet] = intech [unalloc] = intech ) [description] = A Test network [free] = Array ( [address] = 10.0.0.0 [netbits] = 24 [creationdate] = 20041125 ) ) ) ) ) ) This message has been checked for all known viruses by the CitC Virus Scanning Service powered by SkyLabs.

RE: [PHP] Referencing Multi Dimensional Arrays
lol, perhaps embedded a bit too deep in my pre-amble. My question is simply what's a good way to reference a given array entry when you don't know where it is or how deep the array is. I can do a multi dimensional array search and return an array of keys to locate the item, I then want to use that array of keys to be able to reference the data to perhaps do work on it ie: The array is a collection of network data that can consist of address allocation entries or other networks which can contain either more networks or allocations. I call my search function to locate a particular network which returns me an array of keys to locate that entry. I then want to pass that to another function to actually work on the data. I have a search function: $search_result = multi_array_search($net_array,needle); now search_result equals an array of keys to locate the needle, this is variable in count. Sometimes the array of keys is 3 entries other times 5, I want a way of taking those entries and being able to do something like: $net_array[multi-dimensional-key] = value; where sometimes it might be in longhand: $net_array[net1][net2][address1] or other times: $net_array[net1][address1] but you don't know how deep you're going until the search returns you the keys. Hope that clears things a bit!
