Question

I am fetching an array of floats from my database but the array I get has converted the values to strings.

How can I convert them into floats again without looping through the array?
Alternatively, how can I fetch the values from the database without converting them to strings?

---

EDIT:

• I am using the Zend Framework and I am using PDO_mysql. The values are stored one per column and that is a requirement so I can’t serialize them.

• array_map('floatval', $array) only works on single dimensional arrays.

• I can’t floatval the single elements when I use them because I have to pass an array to my flash chart.

• The momentary, non-generic solution is to extract the rows and do array_map('floatval',$array) with each row.

Answer 1

You could use

$floats = array_map('floatval', $nonFloats); 

There is the option PDO::ATTR_STRINGIFY_FETCHES but from what I remember, MySQL always has it as true

Edit: see Bug 44341 which confirms MySQL doesn’t support turning off stringify.

Edit: you can also map a custom function like this:

function toFloats($array) {     return array_map('floatval', $array); }  $data = array_map('toFloats', $my2DArray);
