PHP conditional statement

Conditional statements are used to perform different actions based on different conditions

You can do this by using conditional statements in your code to perform different actions for different decisions.

In PHP, we can use the following conditional statement:

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.

PHP-if...else statement

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

Example

Tip: this example will output "… day!", if the current time (HOUR) is less than 20, otherwise output "… night!".

PHP-if...elseif....else statement

Use the if....elseif...else statement to select one of several code blocks to execute.

Tip: this example will output "Have a good morning!", if the current time (HOUR) is less than 10, if the current time is less than 20, then output "Have a good day!". Otherwise, "Have a good night!" will be output.
