Change order of output based on if condition-CodePudding

I've build my nice page in PHP, but I would like to get a different output order based on the result of a if condition applied at the beginning of the page. IE:

if(condition is true){
    block n1
    block n2 }

else{
    block n2
    block n1 }

Can you kindly advise on what's the best practices in this case? I think a flag should solve the problem, but I'm struggling to understand how.

You could prepare you blocks and then exactly what you wrote :

$block1 = "12345";
$block2 = "67890";

$inverted = true;

if ($inverted===true) {
    echo $block2.$block1;
} else {
    echo $block1.$block2;
}

There are several approaches to this. One would be with if and else and if you have many possibilities, then switch case would be advisable.

$check = 1;

if( $check === 1) { 
    echo `show 1`;
} else {
    echo 'It is not 1';
}

// OR 
switch($check) {
    case 1: 
        echo 'Show 1';
         break;
    case 2: 
        echo 'Show 2';
         break;
    case 3: 
        echo 'Show 3';
         break;
    default: 
      echo 'It is not 1,2,3';
}

u can use array just like that

  $orders = ['a', 'b'];
  if (1 === 1) {
     $orders = ['b', 'a'];
  }

with this you don't need "else" part

  foreach ($orders as $order){
        echo $order."<br/>";
    }
