+## Switch Statements
+Switch statements execute blocks of code based on the value of a condition.  
+
+### Syntax:
+```PHP
+switch(x) {
+  case 1:
+    statement1;
+    break;
+   case 2:
+     statement2;
+     break;
+   default:
+     defaultstatement;
+}
+```
+
+In the above example, x is the condition.  The statements following the case that matches will be executed.  If there are no matches, the default statement(s) will be run.  
+
+The `break` keyword is used to end each case.
