Fetch data in array format in php & mysql

Question

Fetch the data in array format like :

$value = array ("ABC","XYZ","OPQ");

$query = "SELECT * FROM  designation_master";
$result = mysqli_query($mysqli, $query);
while ($row = mysqli_fetch_array($result)) {
    $designation= $row["designation"]; 
}

Need Result:

$value = array ("ABC","XYZ","OPQ");

Answer 1

Fetch the designation column, and push it into an array with the syntax $array[] = $value.

$designation = [];
$query = "SELECT designation FROM  designation_master";
$result = mysqli_query($mysqli, $query);
while ($row = mysqli_fetch_array($result)) {
    $designation[] = $row["designation"]; 
}
print_r($designation);

Answer 2

if the "ABC","XYZ","OPQ" are the same field [designation], you can convert $designation to array.

$query = "SELECT * FROM  designation_master";
$result = mysqli_query($mysqli, $query);
$designation = array();
while ($row = mysqli_fetch_array($result))
{  
    $designation[] = $row["designation"]; 
}
