Question

why doesnt this array work? What do I do wrong? The result of my foreach loop is always either empty or just some weird numbers and signs. So what is wrong with my foreach loop?

$array = array();

while($row = mysqli_fetch_array($result)) {
    if(!empty($row["some"])) {
        $array["some"] = $row["some"];
        $array["some2"] = $row["some2"];
    }

}
foreach($array as $property=>$value) {
echo '<p>'.$value["some"].' - '.$value["some2"].'</p>'; }

Answer 1

$array["some"] and $array["some2"] are specific array elements. You are overwriting them every iteration of your while loop.

Not sure what you’re trying to actually accomplish but I think possibly this is what you want:

$array = array();

while($row = mysqli_fetch_array($result)) {
    if(!empty($row["some"])) {
        $array["some"][] = $row["some"];
        $array["some2"][] = $row["some2"];
    }

}
foreach($array["some"] as $property=>$value) {
  echo '<p>'.$value.' - '.$array["some2"][$property].'</p>'; 
}

or

$array = array();

while($row = mysqli_fetch_array($result)) {
    if(!empty($row["some"])) {
        $array[] = array('some' => $row["some"],
                         'some2' => $row["some2"]);
    }

}
foreach($array as $property=>$value) {
  echo '<p>'.$value['some'].' - '.$value['some2'].'</p>'; 
}

or similar…kinda depends on what you’re ultimately trying to accomplish…
