在PHP和MySQL中以數組格式獲取數據

Question

以數組格式獲取數據，例如：

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

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

需要結果：

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

Answer 1

獲取designation列，並使用語法$array[] = $value將其推入數組。

$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

如果“ ABC”，“ XYZ”，“ OPQ”是相同的字段[名稱]，則可以將$名稱轉換為數組。

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