PHP Switch Case Examples

Learn how to use php switch case statements with examples.

PHP switch case statement

When there is more than one alternative choice present, we use a switch case statement. PHP engine executes the case whose label matches the expression given in a switch parenthesis.

syntax:

switch(expression) {
 case lable-1:
   statements;
   break;
 case lable-2:
   statements;
   break;
...
 default:
   statements;
   break;
}

Example code:

<?php
 $day=4;

switch($day) {
  case 1:
      echo "Sunday"
      break;
  case 2:
      echo "Monday"
      break;
  case 3:
      echo "Tuesday"
      break;
  case 4:
      echo "Wednesday"
      break;
  case 5:
      echo "Thursday"
      break;
  case 6:
      echo "Friday"
      break;
  case 7:
      echo "Saturday"
      break;
  default:
      echo "please enter valid input"
      break;
}
?>

Steps:

1. In the above code, we have created a variable called “day” and assigned a value of 4.
2. Then, we created a switch statement to find the day.
3. If there is a value of 1, then “Sunday” will be printed. Similarly, we have kept 7 days in sequence.
4. Here, we have the value of 4 in the variable “day”, so “Wednesday” will be printed.

Conclusion

You can take input from the user and put it inside a switch statement, then the switch statement will execute according to the input the user gives.
