 Explain switch with the help of a program.

     

The `switch` statement in PHP is used to perform different actions based on 
different conditions. It provides an alternative way to handle multiple conditions 
instead of using multiple `if...elseif...else` statements. Here's an example 
program to demonstrate the usage of the `switch` statement:
```php
<?php
 $day = "Monday";
 switch ($day) {

case "Monday": 

 echo "Today is Monday.";

 break; case "Tuesday":

 echo "Today is Tuesday."; 

 break; case "Wednesday": 

 echo "Today is Wednesday.";

 break; default: 

 echo "Today is not Monday, Tuesday, or Wednesday."; 

 break; 

 }

 ?> ```

In the above example, the value of the variable `$day` is compared with different cases using the `switch` statement. If a match is found, the corresponding code block is executed until a `break` statement is encountered, which terminates the `switch` statement. In this case, since the value of `$day` is "Monday," the code block under the case "Monday" is executed, and the output will be "Today is Monday." If the value of `$day` were "Tuesday," the code block under the case "Tuesday" would execute, and so on
