PHP Switch

The switch statement is similar to the series of if-else statements. The switch statement performs in various cases i.e. it has various cases to which it matches the condition and appropriately executes a particular case block. It first evaluates an expression and then compares it with the values of each case. If a case matches then the same case is executed. 

To use the switch, we need to get familiar with two different keywords namely, break and default.

break: The break statement is used to stop the automatic control flow into the next cases and exit from the switch case.

default: The default statement contains the code that would execute if none of the cases match.

SYNTAX:

switch(expression)

{

    case val1:

        // Code Statement

        break;

    case val2:

        // Code statement

        break;    

    default:

        // Code Statement

}
