If statement-executes code if the specified condition is true

If...else statement-if the condition is true, the code is executed; if the condition is false, the code on the other end is executed

If...elseif....else statement-Select one of several blocks of code to execute

Switch statement-statement one of multiple code blocks to execute

PHP-if statement

The if statement is used to execute code when the specified condition is true.

Tip: this example will output "Have a good day!" if the current time (HOUR) is less than 20.

Use the if....else statement to execute code when the condition is true and another piece of code when the condition is false.
