Help With Counting And Storing Totals

[Rhubarb]

Hi,

As my first project, I am making a 'test' cricket game (I like the deep end!) and have learned lots by doing it this way. However, I need a bit of advice.

I need the $score value in the code below to be cumulative rather than just keep adding the last value and forgetting the previous total.

So, if the score is 5 and the batsmans scores 3 more, the score becomes '8', and then if he scores 3 more, 11, etc...

How do i do this?

<?php 
session_start(); 
if(session_is_registered('myusername')){ 
} 
else{ 
header( "Location: /php/login.php" ); 
} 
require("header.php");
$opponent = $_GET['u'];

$result = mysql_query("SELECT * FROM user WHERE username='$myusername'")
or die(mysql_error());  

$row1 = mysql_fetch_array($result) or die(mysql_error());

$result = mysql_query("SELECT * FROM user WHERE userid= '$opponent'")
or die(mysql_error());  

while($row = mysql_fetch_array($result)){

echo "<table width='600' align='center' border='1'>";
echo "<tr><td>";
echo "Batsmans Skill = ", $row['skill'];
echo "<br><br>Bowlers Skill = ", $row1['skill'], "<br><br>";

$oppskill=$row['skill']/$row1['skill']*50;
$rand=rand(1,100);

if ($rand>=$oppskill) {
	echo "OUT";
} 

else {
	[COLOR="Red"]$runs=0+rand(1,6);
	$score=$runs+$runs;
	echo "Result Of Bowl = ",$runs;
	echo "<br><br>Batsmans Score = ",$score;[/COLOR]}
echo "</td></tr>";
echo "</table>";
}
?>

Any advice would be much appreciated!

$score = $score + $runs ?

Not sure where you'd want it to be put, but that will take the value of $score and add to it the new value of $runs.....

Or to simplify:

$score .= $runs

.= will add the portion after the = to the existing value of the variable before the .=

Ah, except the . character means concatenate.... not sum. So to use your method, you'd want $score += $runs;

[cyclefiend2000]

if you make $runs into an array, you could do the following....

$score=array_sum($runs);

maybe like this...

$i=0;
if ($rand>=$oppskill) {
	echo "OUT";
} 

else {
	$runs[$i]=0+rand(1,6);
	$score=array_sum($runs);
	echo "Result Of Bowl = ",$runs[$i];
	echo "<br><br>Batsmans Score = ",$score;
    $i++;}
