Answer 1

You can use substr() or substr_replace() for this purpose. Try with either

$words = "Unbelievable";
echo substr($words, 0, 1) . ' ' . substr($words, 1);

or

echo substr_replace($words," ", 1, -strlen($words));

Answer 2

Use substr()

$words = "Unbelievable";
$str1 = substr($words, 0, 1); //set str1 to be Un
$str2 = substr($words, 1); //set str2 to be believable

$result = $str1." ".$str2; //result is 'Un believable'

Answer 3

 $words = "Unbelievable".    
$word = substr_replace($words," ", 1, -strlen($words));
