This says that when we visit http://you.rock/stringhelpers, we’ll initialize a basic string which will contain the text We like to program in PHP and we like to use the Laravel Framework! Then we’ll call our helper functions via static methods and var_dump the result to the screen.

string 'We like to program in PHP and we like to use the Laravel Framework!' (length=67)
 
string 'like to program in PHP and we like to use the Laravel Framework!' (length=64)
 
string 'We like to ' (length=11)
 
string 'like to program' (length=15)
 
string ' to ' (length=4)
 
array (size=2)
  0 => string 'We like to' (length=10)
  1 => string 'we like to' (length=10)
 
string ' program in PHP and  use the Laravel Framework!' (length=47)
