Question

Why will my array have different output within the while loop, like it fetch all data from database in json, but once I declare the array outside of the while loop as commented out it gives output single row in json? Am I missing something basic or what? Thanks in advance

$query = "SELECT * from creative ORDER BY rand()";

$rs = mysql_query($query);

//$arr = array();

while ($obj = mysqli_fetch_object($rs)) {

    $arr[] = $obj;

    $cid = $arr -> id; //get id

} 

if (isset($imei) && !empty($imei)) {

$add = array('delay'=>"1800000"); //Add Objects to JSON Encoded Array

$arr[] = $add;

echo json_encode($arr);

Answer 1

Have you tried array push?

    $arr = array();
    while ($obj = mysqli_fetch_object($rs)) {

        //$arr[] = $obj;
        array_push($arr, $obj);
        //$cid = $arr -> id; //get id
    }
