There is a short function, which starts one query and then parse the results.
If the script goes to commented line, the $ret array new value makes a recursive array.
I checked set the value by hand, like ='35';, but the PHP do the same.
I think it's a bug, because I downgrade the v5.3.27 and the script functional normally again.

Test script:
$ret = Array();

$query = "SELECT * FROM any WHERE ID=".html2sql($ID).";";
$results = mysqli_query($connectedID, $query);
if (mysqli_num_rows($results)) {
    $i = 0;
    while ($row = mysqli_fetch_assoc($results)) {
	$r[$i]['GyujtoEgysegID'] = $row['GyujtoEgysegID'];
	$r[$i]['EgysegID'] = $row['EgysegID'];
	$r[$i]['Jogosultsag'] = $row['Jogosultsag'];
    $j = 0;
    foreach ($r as $d) {
	if ($d['GyujtoEgysegID'] != '') {
		$gye = GET_user_egysegGyujto($d['GyujtoEgysegID']);
		foreach ($gye as $e) {
			$ret[$j]['EgysegID'] = $e['EgysegID'];
			$ret[$j]['Jogosultsag'] = $d['Jogosultsag'];
	}else {
		$ret[$j]['EgysegID'] = $d['EgysegID']; // This is goes RECURSIVE
		$ret[$j]['Jogosultsag'] = $d['Jogosultsag'];
	return $ret;
}else {
	return false;

Expected result:
Something like this:
$ret = Array([0] => Array('EgysegID' => 2, 'Jogosultsag' => 1), Array...

Actual result:
$ret = Array([0] => Array('EgysegID' => 2, 'Jogosultsag' => 1), Array([1] => [1] => *RECURSIVE*

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

That script isn't something we can use to reproduce the issue. It needs to be as self-contained as possible: no database, no other functions called, and not an excerpt of some code from within a function.

Also, the "expected result" is probably not what you actually expect (shouldn't it be [1] => Array... at the end?) and the "actual result" isn't possible ([1] => [1] => is invalid).
