array_sum() - how to use?

[Tim Mousel]

Hi,

I found array_sum() in the manual but I'm having a hard time applying it. Maybe there is a different way I should be approaching this?

I want to get a total for all the values of $estimate[$t].

for($t=0; $t<= ($number - 1); $t++) {
$estimate[$t] = ($width[$t] + $length[$t]);
$temp = $t + 1;
echo "<BR>$estimate[$t] is estimate $temp<BR>";
} 

Is array_sum() what I would use and how would it be used?

Thanks,

Tim

yes, "array_sum()" is what you want...

if you want all the "$estmiate[]" values to sum up into one variable - then do this:

$total = array_sum($estimate);

and if $estimate is this:
$estimate[0] = 1;
$estimate[1] = 3;
$estimate[2] = 12;

then $total will be "16";
