min(array) but ignoring 0s

[debz89uk]

I have any array $DF containing numeric variables, I want the minimum value of the array stored in $val but ignoring any zeros i.e. the lowest number that is not 0.  Is this possible?

Pass the array through array values, then to the min function.

 

$arr = array_values($DF); //array values with no second argument, strips out any value that is equivalent to boolean false.  This includes integer 0, or string 0.
$val = min($arr);

$val = min($arr);

 

I think you are referring to array_filter as array_values will just return all values from an array including zero's and other false-like values.

Yes, ignace, I meant array_filter() sorry.  Thinking one thing, typed another.
