Question

I have a problem with converting string to float.

print gettype($value[$id]); //returns string

var_dump($value[$id]);//returns string '34,7140' (length=7)

$float = floatval($value[$id]); 

print gettype($float);//returns double

var_dump($float);//returns float 34

echo $float;//returns 34

I don’t understand why “34” ? Why $float is not ‘34,7140’?
How can I get $float = 34,7140 ?

Answer 1

The problem is that floats are expected to be in the English format with a . separating the decimal part, not a comma. If the format is always the same with a single comma, use this:

$float = (float)str_replace(',', '.', $value);
