Question

Variable $name (string) gives something like (possible values):

"Elton John"
"2012"
" George Bush"
" Julia"
"Marry III Great"

Want to catch the first letter of $name and add it to $letter variable.

It’s important how many words (divided with spaces ” “) the string has:

1. If there is just one word, set $letter to the first letter of the first word.

2. If there is more than one word, set $letter to the first letter of the second word.

3. If $name is empty, set $letter to 'undefined'.

Thanks.

Answer 1

$names = explode(' ', trim($name));
if (empty($names))
    $letters = 'undefined';
else if(count($names)==1)
    $letters = substr($names[0],0,1);
else 
    $letters = substr($names[1],0,1);
