The code processes each element in the$colorsarray. It converts each color to uppercase and prints it. The loop continues while the index is less than the array length. Note array bounds are checked. Nested do-while Loops This example demonstrates nested do-while loops for a multiplication t...
In our example below, we skip the iteration wheneverxequals3. <?php$x=1;do{if($x==3){$x++;continue; }echo"The value of x is ".$x."";$x++; }while($x<=5);echo"Exited the do while loop.";?>Copy As you can see in our output below, we did not print any data when the...
