String- and numeric-comparison operators.

   
String operator            Comparison operation                   Equivalent numeric operator 
lt                         Less than                              < 
gt                         Greater than                           > 
eq                         Equal to                               == 
le                         Less than or equal to                  <= 
ge                         Greater than or equal to               >= 
ne                         Not equal to                           != 
cmp                        Compare, returning 1, 0, or -1         <=> 

Here are some examples of string-comparison operators in action: 

$result = "aaa" lt "bbb"; # result is true 
$result = "aaa" gt "bbb"; # result is false 
$result = "aaa" eq "bbb"; # result is false 
$result = "aaa" le "aaa"; # result is true 
$result = "aaa" ge "bbb"; # result is false 
$result = "aaa" ne "aaa"; # result is false 
$result = "aaa" cmp "bbb"; # result is -1
