Add sql entries

[Anon]

I've got a SQL table with alot of entries (FLOAT entries). I want to add all of these entries into one number ...

i've got all the numbers into a array ( i think), i just need a little help with the loop ... i really have no clue how to do this, but a little tip would be appriciated !

Thanks in advance !

Mybe this will work

$floatSum = 0;

foreach ($yourArrayHere as $arrayKey => $arrayValue)
{
$floatSum += (float)$arrayValue;
}

What does this code do ?

It cycles through the array, typecasts each value as float and adds it to $floatSum.

This should do the trick 😛

That was probably what i was looking for, but i get a kinda weird warning msg :

Warning: Invalid argument supplied for foreach() in serie.php on line 99

When i do this:

$array = mysql_query("SELECT * FROM $db_blah WHERE id='$yup'");
$goink = mysql_fetch_array($array);

$floatSum = 0;
foreach($goink["values"] as $arrayKey => $arrayValue)
{$floatSum += (float)$arrayValue;}

print "$floatSum";
