php do

Recently i discovered you can't use do as a class method.

class Activate
{
function do()
{
return "it's good for you.";
}
}

if you want to use Activate::do() you will get an error.

simple word to number and number to word functions

I saw this python blog post and i wondered how the functions translate to php.

// to make the function language independent i put the array outside the functions
$array = array('zero','one','two','three','four','five','six','seven','eight','nine');
// number to words function
function d_to_w($digits,$array)
{
$temp = preg_split('//', $digits, -1, PREG_SPLIT_NO_EMPTY);
$return = array();
foreach($temp as $check)
{
if(is_numeric($check))
{
$return[] = $array[$check];
}
}
return implode(' ',$return);
}
// words to number function
function w_to_d($word,$array)
{
$temp = preg_split('/(\.|,|;|:| )/',$word, -1, PREG_SPLIT_NO_EMPTY);
$return = array();
foreach($temp as $check)
{
$temp2 = array_search(strtolower($check), $array);
if(is_numeric($temp2))
{
$return[] = $temp2;
}
}
return implode('',$return);
}

I've added a check to make the function more real world usable. An example use of the functions is;

echo d_to_w('100',$array).'
'.w_to_d('one zero zero',$array).'
';
echo d_to_w('1.00',$array).'
'.w_to_d('one,zero zero',$array).'
';
