Just to add onto streetparade's answer

foreach ($array as $decval)
{
  echo $decval;
}

returns raw dec for the characters.

function ascii_to_dec($str)
{
  for ($i = 0, $j = strlen($str); $i < $j; $i++) {
    $dec_array[] = ord($str{$i});
  }
  return $dec_array;
}

example usage :

$ascii ="\t";
print_r( ascii_to_dec($ascii));

returns an array 

Array
(
    [0] => 9
)

ord() returns the integer ascii value of a character

chr() returns a character from an ascii value
