PHP switch Statement (original) (raw)

Last Updated : 15 Feb, 2023

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.

Flowchart of switch statement:

Syntax:

switch(expression) { case val1: // Code Statement break; case val2: // Code statement break; ...

default:
    // Code Statement

}

Example 1: The following code demonstrates the switch statement.

PHP

<?php

`` $x = 2;

`` switch ( $x ) {

`` case 1:

`` printf( "Choice is 1" );

`` break ;

`` case 2:

`` printf( "Choice is 2" );

`` break ;

`` case 3:

`` printf( "Choice is 3" );

`` break ;

`` default :

`` printf( "Choice other than 1, 2 and 3" );

`` }

?>

Example 2:

PHP

<?php

`` $n = 'C' ;

`` switch ( $n )

`` {

`` case 'A' :

`` case 'B' :

`` printf( "A and B\n" );

`` break ;

`` case 'C' :

`` case 'D' :

`` printf( "C and D\n" );

`` break ;

`` default :printf( "Alphabet is greater than D\n" );

`` }

?>
