PHP SWITCH STATEMENT - PHP LESSON 9 STUDENTSBLOG100

In switch statements multiple cases are used. Each case contain one condition. The case which is matched with the switch variable will be executed. 

Syntax:

switch (variable) { case "this-value": //Code to execute if variable == this-value; break; case "that-value": //Code to execute if variable == that-value; break; default: Code to execute if variable does not equal to any case conditions; break; } Example:

<?php $grade="B"; switch ($grade) { case "A": echo "Excellent"; break; case "B": echo "Well done"; break; case "C": case "D": echo "You passed"; break; case "F": echo "Better try again"; break; default: echo "Invalid grade"; } echo "<br>your grade is : ".$grade; ?>
Output:

Well done
your grade is : B

In the above program, initially we have declared variable grade as B. And totally six cases are introduced with different conditions. In which the variable grade is assigned as B so case B matched and thus case "B" block is executed.

If none of the case is matched, the default block will be executed.
