switch allows you to select multiple possible results for a scalar (expression).

Grammar:

Switch (expr) {case   result1:   statement1 break   ;   Case RESULT2:   statement2 break   ;   ... Default   

The system calculates the value of expr, according to the calculation results (RESULT1, RESULT2, etc.) to select the following corresponding execution statement, if all case results are not met, will execute the statement in default.

<?php switch ($x) {case   0:   echo "x equals 0";   break;   Case 1:   echo "x equals 1";   break;   Case 2:   echo "x equals 2";   break;   Default
