[Resolved] Concatenation help

[wad]

I'm looking for a way to concatenate a string being processed through a for loop.

Basically, I'm passing a variable into an array (using explode). This array can have anywhere from 1 to inf items in it. Currently, I'm passing the array through a for loop and echoing the data from there.

Data comes in form "2,4,8,6,", so an array $explodeResults[$l] is created. I loop based on another variable which knows how many numbers were included in this variable. The loop echos a simple statement "Dice $n was of value $explodeResults[$l]" and then repeats for as many as needed.

I want the information to be displayed like this:

Dice 1 was 2<br>
Dice 2 was 4<br>
Dice 3 was 8<br>
Dice 4 was 6

But have that all concatenated into another string value. The other string value would be like "You rolled 4d8 with a modifier of +0 and the total was 20"

The end result should be:

You rolled 4d8 with a modifier of +0 and the total was 20.

Dice 1 was 2
Dice 2 was 4
Dice 3 was 8
Dice 4 was 6

Is there a way to do what I'm asking. If further clarification is needed, please let me know. Thank you.

Here. Some of it won't be relevant to the issue at hand, but I'll post it anyways.

<?php
	// Purpose: Get the passed variables from dice script
	//          and parse them to readable data, then post
	//		to the thread.

mysql_connect("localhost", "dbuser", "dbpass");
mysql_select_db("superwad_invision");

$n		= $_GET['n'];
$dx		= $_GET['dx'];
$mod		= $_GET['mod'];
$pm		= $_GET['plusmin'];
$total		= $_GET['total'];
$results                   = $_GET['results'];
$ipbcookie	= $_COOKIE['invisionmember_id'];
$postTime	= date("U");

// Place the results into an array for easier display.

$explodeResults = explode(",", $results);

// Set modifier variable

if ($pm == '0')
{
	$plmi = "+";
}
elseif ($pm == '1')
{
	$plmi = "-";
}

// Is the user a guest?

if ($ipbcookie == '0')
{
	$guest = '1';
}
else
{
	$guest = '0';
}

// Get username from cookie information if not a guest

if ($guest == '0')
{
	$result = mysql_query("SELECT name from ibf_members WHERE id = $ipbcookie");
	$row = mysql_fetch_row($result);
	$userName = $row[0];

$postString = "$userName rolled ". $n ."d". $dx . " with a modifier of ". $plmi ."". $mod. " and the total was $total.";

for ($l = 0; $l < $n; $l++)
{
	$res = $l + 1;
	echo ("Dice $res was a $explodeResults[$l]<br>");
}

$result1 = mysql_query("SELECT posts FROM ibf_forums WHERE id = '16'");
$row1 = mysql_fetch_row($result1);
$posts1 = $row1[0];
$updatePosts1 = $posts1 + 1;

mysql_query("UPDATE `ibf_forums` SET `posts` = '$updatePosts1', `last_post` = '$postTime', `last_poster_id` = '10', `last_poster_name` = 'DiceBot', `last_title` = 'Rolling Thread', `last_id` = '31' WHERE `id` = '16'");

$result2 = mysql_query("SELECT posts,ip_address FROM ibf_members WHERE id = '10'");
$row2 = mysql_fetch_row($result2);
$posts2 = $row2[0];
$updatePosts2 = $posts2 + 1;

mysql_query("UPDATE `ibf_members` SET `posts` = '$updatePosts2', `ip_address` = '' WHERE `id` = '10'");

$result3 = mysql_query("SELECT posts FROM ibf_topics WHERE tid = '31'");
$row3 =	mysql_fetch_row($result3);
$posts3 = $row3[0];
$updatePosts3 = $posts3 + 1;

Hey there. Just wondering if you've made any progress on this.

[Cailean]

So, if I understand, these lines produce the output you want, but you like it all contained in one string variable?

$postString = "$userName rolled ". $n ."d". $dx . " with a modifier of ". $plmi ."". $mod. " and the total was $total.";
for ($l = 0; $l < $n; $l++)
    {
        $res = $l + 1;
        echo ("Dice $res was a $explodeResults[$l]<br>");
} 

If that's the case, try this:

$postString = "$userName rolled ". $n ."d". $dx . " with a modifier of ". $plmi ."". $mod. " and the total was $total.";
$newString=$postString."<br />";
for ($l = 0; $l < $n; $l++)
    {
        $res = $l + 1;
        $newString+="Dice $res was a $explodeResults[$l]<br>";
}

echo $newString; 

or you could not bother with $newString and just use $postString+="Dice $res...

[wad]

Hmm...

I tried that code, but for some reason $newString contains a "0" and nothing more...

[Cailean]

DUH!!! {brain fart}

$postString = "$userName rolled ". $n ."d". $dx . " with a modifier of ". $plmi ."". $mod. " and the total was $total."; 
$newString=$postString."<br />"; 
for ($l = 0; $l < $n; $l++) 
    { 
        $res = $l + 1; 
        $newString.="Dice $res was a $explodeResults[$l]<br>";  // NOTE THE CHANGE HERE!!!
} 

echo $newString;

You sire, are awesome!
