An example of how to use a switch statement in PHP:
<?php
$dayOfWeek = "Monday";
switch ($dayOfWeek) {
case "Monday":
echo "Today is Monday";
break;
case "Tuesday":
echo "Today is Tuesday";
break;
case "Wednesday":
echo "Today is Wednesday";
break;
case "Thursday":
echo "Today is Thursday";
break;
case "Friday":
echo "Today is Friday";
break;
default:
echo "It's the weekend!";
}
?>
Explanation:
In this example, we define a variable $dayOfWeek that contains a string value of “Monday”. We then use a switch statement to check the value of this variable, and execute different code depending on the value.
The first case in the switch statement checks if $dayOfWeek is equal to “Monday”, and if it is, the code echo “Today is Monday”; is executed. The break; statement is used to exit the switch statement and prevent the code in other cases from being executed.
If $dayOfWeek does not match any of the cases, the code in the default: case is executed, which in this example outputs the message “It’s the weekend!”.
Switch statements are useful when there are multiple possible values for a variable, and different code needs to be executed depending on the value.
