This might help you I am using PDO and trying to display how many users are in a table, however I get this error: , You should try to count the users in query, like so:
code :
public function CountUsers() {
    $query = "SELECT COUNT(1) FROM Users";

    $statement = $this->_dbHandle->prepare($query);

    if($statement->execute()) {
        // This will return COUNT(1) field
        return $statement->fetch(PDO::FETCH_NUM)[0];
    }else{
        return 0; // should the query fail, return 0
    }
}
return count($statement->fetchAll(PDO::FETCH_ASSOC));
function CheckUsers() {
    $userCount = CountUsers();
    if($userCount == 0) {
        echo 'No users found';
    }else{
        echo $userCount . ' users found';
    }
}

I wish this help you If your array is always structured like that with 0 as a word and 1 containing an array of related words, then:
code :
echo $data[0];

foreach ($data[1] as $value) {
  echo $value;
}

Any of those help You'll need to cast the objects to arrays first, to make it a 2d-array:
code :
array_walk(
    $ordersArray,
    function (&$row) {
        $row = (array) $row;
    }
);
$this->excel->getActiveSheet()->fromArray($ordersArray, NULL, 'A1');

With these it helps I'm trying to echo the values of an associative array that contains all the rows in a table using foreach in a table. , You need to change:
code :
$cartRows = mysqli_fetch_all($result);
$cartRows = mysqli_fetch_all($result,MYSQLI_ASSOC);

it helps some times As you said:- I need to extract the [created] field from the last element of the nested array in [records].
first count the number of records in records sub-array and then get the data:-
code :
<?php
  $count = count($target['records']); // count number of record in records sub-array
  echo $target['records'][$count-1]['created']; // get last created from records array
?>

around this issue The problem is with [] in $boxesInfo[] = LoadBoxes(); Your function LoadBoxes() returns an array of boxinfo, and you assign that to an array. So the loop just sees an array with one element, which is itself another array. If you change the line to $boxesInfo = LoadBoxes(); you should get the expected result.
On second thought, loadBoxes() returns an array of boxes, which are themselves arrays, so you would need nested loops to get the info of all boxes:
code :
foreach($boxesInfo as $box) {
    foreach($box as $arrayKey => $info) {
        echo $arrayKey.' '.$info;
    }
}
