php switch

DrRakha

In switch statement , you can check for many conditions at once .and this is depending on the variable give to the switch .you use switch instead of writing condition in form of if/elseif/elseif/elseif/elseif ... in the next part you will find an example for using switch .

PHP Switch Statement Example

Code:

<?php $number = 1;
echo "my number is $number<br />";
switch ($number){
    case 1:
        echo "your team is  x";
        break;
    case 2:
        echo "your team is  y";
        break;    
    case 3:
        echo "your team is  z";
        break;    
    case 4:
        echo "your team is  e";
        break;
    case 5:
        echo "your team is  r";
        break;    
} 

what you think the output is ? :confused:

the output is

Code:

my number is 1
your team is  x

So, the switch operating work on the $number and search for the case when have same value of $number then execute the segments cross ponding to the case. the break; keyword prevent the other case from being executed .If u didn't write it ,all other cases after the case of correct condition will be executed .

The default case :

It is the case that will be executed when no other cases before it is achieved.

example on default case :

Code:

<?php $number = 132;
echo "my number is $number<br />";
switch ($number){
    case 1:
        echo "your team is  x";
        break;
    case 2:
        echo "your team is  y";
        break;    
    case 3:
        echo "your team is  z";
        break;    
    case 4:
        echo "your team is  e";
        break;
    case 5:
        echo "your team is  r";
        break;    
      default:
        echo "your number is not recorded !";
        break;
} 

what you think is the output of this code ?

The output is :

Code:

my number is 132
your number is not recorded !
