如何獲得一個表中的PHP

Question

使用PDO的列名任何人可以幫助我對此...我的代碼如下：

$STH = $DBH->query('SELECT id,zone,latlng FROM `rl_zones`'); 
$STH->setFetchMode(PDO::FETCH_ASSOC); 

while ($row = $STH->fetch()) { 
    // here i need column names i.e id,zone,latlng. 
    // i want to display those column names.... 
} 

感謝

Answer 1

使用這樣

$column_name = array_keys($row); 
print_r($column_name); 

你會得到你所需要的;

Answer 2

PDO中使用PDO::FETCH_COLUMN

$STH = $DBH->prepare("DESCRIBE rl_zones"); 
$STH->execute(); 
$table_fields = $STH->fetchAll(PDO::FETCH_COLUMN); 
print_r($table_fields);
