Can anyone help me with the following $var question thanks?:

 

Extract and add together the numeric values from the string $var

$var = '{"val_a":7,"val_b":5,"val_c":4,"val_d":6,"val_e":5}';

something like:

$array=explode(',',$var);
foreach($array as $value)
{
list($junk,$number)=explode(':',$value);
$count+=$number;
}

That string is JSON encoded string, so using the function json_decode and then use array_sum on the resultant array.
