Never use a for(;;) loop to iterate over an array: you are creating
error-prone code.
Either use foreach() with references:
<?php
foreach($array_with_numbers as &number)
str_replace(',', '.', $number);
?>
Or use array_map to automatically transverse the array applying a function
to every element, or (even better) use a recursive function.
Or, you can RTFM. http://php.net/str_replace , the part that says:
"If subject is an array, then the search and replace is performed with every
entry of subject, and the return value is an array as well."
So, please go RTFM.
