Place the string Now is the time for all good men. into the second index of an array
The string located at the second index of the array is: Now is the time for all good men.
The third character of the Now is the time for all good men. string at the second index of the array is: w

Explode the string  Now is the time for all good men.  into an array
Array
(
    [0] => 
    [1] => Now
