Is it really this bad to use goto in a switch statement? Imo this is much more user-friendly as far as readability AND code-maintenance is concerned.

bar.php

<?php
$complexArray = [
     //... lots of stuff
     'condition' => 'unknown'
];

switch ($someThingElse) {
     case 'foo':
     default:
          $complexArray['condition'] = 'foo';
          break;
     case 'bar':
          if ($otherCondition === false) {
               $complexArray = addCondition($complexArray, 'bar');
               break;
          }
          
          $complexArray['condition'] = 'bar';
          break;
}

function addCondition($baseArray, $condition) {
     $baseArray['condition'] = $condition;
     
     return $baseArray;
}

$service->call($complexArray);

foo.php

<?php
$complexArray = [
     //... lots of stuff
     'condition' => 'unknown'
];

switch ($someThingElse) {
     case 'foo':
     default:
     foo:
          $complexArray['condition'] = 'foo';
          break;
     case 'bar':
          if ($otherCondition === false) {
               goto foo;
          }
          
          $complexArray['condition'] = 'bar';
          break;
}

$service->call($complexArray);
