Conditions

Conditions allow for the use of logic, and can execute different blocks of code if
different logic conditions are met. One basic example is comparing number variables to
have different blocks of code executed if the numbers are greater than, less than, equal to, etc.

$foo = 15
$bar = 25
15 is less than 25

$foo = 37
$bar = 18
37 is greater than 18

$foo = 15
$foo is equal to 15

$foo = 37
$foo is not equal to 5, 10, or 15
