Bug introduced by
The expression $this->addAlias($this->sortFields) of type string|array is not guaranteed to be traversable. How about adding an additional type check?

There are different options of fixing this problem.

  1. If you want to be on the safe side, you can add an additional type-check:

    $collection = json_decode($data, true);
    if ( ! is_array($collection)) {
        throw new \RuntimeException('$collection must be an array.');
    }
    
    foreach ($collection as $item) { /** ... */ }
    
  2. If you are sure that the expression is traversable, you might want to add a doc comment cast to improve IDE auto-completion and static analysis:

    /** @var array $collection */
    $collection = json_decode($data, true);
    
    foreach ($collection as $item) { /** .. */ }
    
  3. Mark the issue as a false-positive: Just hover the remove button, in the top-right corner of this issue for more options.

Bug introduced by
It seems like $fieldNames defined by $this->addAlias($collect...lds'], $collectionName) on line 72 can also be of type string; however, Soupmix\SQLQueryBuilder::returnFieldsForJoin() does only seem to accept null|array, maybe add an additional type check?

If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check:

/**
 * @return array|string
 */
function returnsDifferentValues($x) {
    if ($x) {
        return 'foo';
    }

    return array();
}

$x = returnsDifferentValues($y);
if (is_array($x)) {
    // $x is an array.
}

If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.
