Looping though an array

[Anon]

I have an array and it's holding several Numbers

i.e

166
224
345
367

I want to loop though it and add up those number and print a total.

Can any body help
I'm using PHP3 so I can't use the foreach()
went nuts before I relized it was only a php4 function
TIA

Within the manual under foreach are examples on using while() , have a look :

http://php.net/manual/en/control-structures.foreach.php

Essentially :

reset ($array);
while (list(, $value) = each ($array)) {

$sum += $value;

}

print $sum;

Still can't get all the values add up only print the last value.

<? // get sub total
$gtotal = explode("\n","$total"); // $total being a variable containing a list of values
}
reset ($gtotal);
while (list(, $s_total) = each ($gtotal)) {
$sum += $s_total;
}
echo $sum;
?>

// so $total has
// 53
// 301
// only echoing 301
// need to add 53 and 301 and what ever
//values that variable holds

TIA
