You could use explode(), here's how it works...
[code]<?php
$ip = "192.168.1.2";
$bits = explode(".",$ip);
echo $bits[0]; //Prints 192
echo $bits[1]; //Prints 168
echo $bits[2]; //Prints 1
echo $bits[3]; //Prints 2
?>[/code] -
Moved to our 3rd party scripts forum - The PHP Newbie Help forum is for requesting help with custom scripts that you are developing yourself - Not for requesting help with 3rd party scripts.

Yeah, that should be fine, you could probably even do it with a foreach() for less typing...
[code]<?php
$str = "";
foreach($_POST['category'] as $x) {
$str = $str.$x.",";
}
$str = substr($str,0,-1);
?>[/code] -
Just ran a few tests, and finaly managed to get it to [i]not[/i] work for me. Think I made a silly mistake in my code... Try replacing this line:[code]$newname = $random.substr($filename,$pos);[/code]
-
Try this: [code]<input name='category[]' type='checkbox' dir='ltr' value='9,' /.>
<input name='category[]' type='checkbox' dir='ltr' value='10,' />
<input name='category[]' type='checkbox' dir='ltr' value='11,' />
<input name='category[]' type='checkbox' dir='ltr' value='12,' />
<input name='category[]' type='checkbox' dir='ltr' value='13,' />[/code]
You can then try this on your processing page to see how its structured:
[code]<?php
echo "<pre>";
print_r($_POST['category']);
echo "</pre>";
?>[/code] -

I mean I can't use php's htmlentities() function on every echoed text, can I?[/quote]
You can, although what I do is just type the entities instead of the actual character - Just a matter of habit now...
[code]<?php
echo "I really fancy some tea & crumpets!";

Putting four zeros is pointless. If you want to always have a four digit number, then you have to set the minimum random value to start with one thousand:
$random = rand(1000, 9999);[/quote]
An option could be to use str_pad(rand(0,9999),4,"0",STR_PAD_LEFT); should you wish to have four digits starting from 0000 to 9999.

With regards to the main question, I can't see why my original code doesn't work, along with Toplay's revision. I'll post it up again with comments to show whats going on:
[code]<?php
$filename = $_FILES['ulfile']['name']; //Lets call it test.txt
$random = str_pad(rand(0,9999),4,"0",STR_PAD_LEFT); //Pick a number between 0000 and 9999
$pos = strrpos($filename,"."); //Get the location of the last period we can extract the extension
$newname = $random.substr($filename,$pos * -1,$pos); //Add the random number to the extension .txt
?>[/code] -
You can just pull the required information from your database, loop through it and create the entereies in the select box. Here's an example:
[code]<?php
$result = mysql_query("SELECT `name`,`id` FROM `table`") or die(mysql_error());
echo "<select name='names'>";
while($row = mysql_fetch_assoc($result)) {
echo "<option value='$row[id]'>$row[name]</option>";
}
echo "</select>";
?>[/code] -
There are a number of topics already regarding prefered editors, a quick look turned up the following two that you may wish to read and/or participate in:
[a href=\"http://www.phpfreaks.com/forums/index.php?showtopic=54859\" target=\"_blank\"]Which PHP-Editor do you think is the best?[/a]
[a href=\"http://www.phpfreaks.com/forums/index.php?showtopic=93740\" target=\"_blank\"]PHP Coding software[/a]

I see no reason as to why this topic should be closed, so I have opened it so others can feel free to have their input on the mentioned software, or recommend alternatives. Without creating new topics on the same, or similar theme.

Check the manual for the following functions:
imagesettile()
imagefill()
Those should get you on the way. -
This [i]should[/i] work...
[code]<?php
$filename = $_FILES['ulfile']['name'];
$random=rand(0000,9999);
$pos = strrpos($filename,".");
$mpos = "-".$pos; //Not sure if substr would work with -$pos as a parameter, so created this var.
$newname=$random.substr($filename,$mpos,$pos);
?>[/code] -
As far as I was aware, GMT and UTC are the same thing.
To add 5 hours, you could do it like this. You can add 18000 to the seconds if you prefer though output would be the same.
[code]<?php
echo date("DdSF,Y g:i:sa",mktime(date("g")+5,date("i"),date("s"),date("m"),date("d"),date("Y")));
?>[/code]
As for making it DST correct, I guess you could use a switch() to match the current month, and if DST applies add/remove an hour. -
Nice, looks Mozilla like, kinda.

Alright. Fixed a few things while I had a bit of spare time before the meeting. The logo is clickable. I took out the login box and sized up the nav. There is now /login.php . However, what do I do with the login page? I stared at it for a while, just kinda looking at it, trying to think of something, but nothing came to mind. Any ideas on how to spice up that oh so empty page? Any ideas where I should move the login box instead?

The open source version of Maguma Studio - I use it and appears to have many of the features you have described. The cool thing is, when you type a function, a tooltip pops up explaining its use and acceptable parameters.
One annoying thing is, its not 100% stable, sometimes it decides to throw a tonne of error messages out at once, reload it and all is ok again. Doesn't happen ALL the time, just every so often. But as its open source, I would image it will get fixed soon. -
There is a class called SS_ZIP that I use for creating zip archives without any problems. You can find it [a href=\"http://www.smiledsoft.com/demos/phpzip/\" target=\"_blank\"]here[/a].

Ok, I came up with a workaround - I just used some CSS to recolour the scrollbar to the same as the background.
-
I'm opening a new window and require it to fill the entire screen, currently I have this:
[code]window.open('file.php','','fullscreen=yes,scrollbars=no');[/code]
I am getting a fullscreen window, but I still have an inactive vertical scrollbar - I just can't get rid of the thing! Does anyone have any suggestions?
NOTE: This is not for a live public application, I'm not trying to be annoying for the users - There are none! I'm wanting to display a project on a plasma screen without all the browser bits. -
There is a function reference over at php.net.
As for iterating through a string, you have the right idea - Just to expand on it though...
[code]<?php
$str = "The quick brown fox jumped over the lazy dog";
for($i=0; $i<strlen($str); $i++) {
echo $str[$i]."<br/>";
}
?>[/code] The above will go through the whole of $str and print each character on a new line...
[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]I also need to construct a Select Case:[/quote] I don't understand what you mean, care to elaborate?
[b]EDIT:[/b] I just done a search on Google for Select Case, and it appears that its equivilent in PHP is the switch statement, used like this:
[code]<?php
$number = 1;
switch($number) {
case 0:
echo "Number is zero";
break;
case 1:
echo "Number is one";
break;
default :
echo "Number is not zero or one";
}
?>[/code] -
The command would be something like:
0 3 * * * /usr/local/bin/php /usr/home/*username*/public_html/script.php
The second part of the command "/usr/local/bin/php" points to the PHP install on the server, the script is run through the command line rather than through Apache. -
Is XMB open source, or do you have the source? If so, why not take a look at it and see how they have done it for some ideas...

is it a bad idea to use function called
str_pad()
just was curious if it is what u need....

Yes, that would be an easier solution - I knew I saw that function in the manual a while back, couldn't remember what it was called - After searching for it, and not finding it, I thought I imagined it! Hah!
