This is just a revision of using PHP for loop and switch conditional case statement after somebody ask me a very simple question of how to use them together today.
The following PHP codes are a very typical example of using for loop and switch conditional case statement together. I think you should use them this way for many many times. Let’s just get a quick and brief revision.
<?php $var4 = "Alex"; $var5 = "Kathy"; for($i = 4; $i<= 5; $i++){ switch ($i){ case 4: echo "This is: " . $i; ....................... ... more codes here ... ....................... break; case 5: echo "This is: " . $i; ........................ ... more codes here ... ........................ break; } // end switch statement echo "<br>"; echo "The person is: " . ${"var".$i}; echo "<br>"; } // end for loop ?>
This is very clear that the PHP for loop will run two times, and different codes will be executed depend on the value of i with the using of switch conditional statement.
The output of the above codes are:
This is: 4
The person is: Alex
This is: 5
The person is: Kathy
Please note how we can get the value of a variable as below:
${"var".$i};
