PHP MySQL获取列名称迭代所有记录

Question

$query = mysql_query("SELECT * FROM mytable");

while ($row = mysql_fetch_assoc($query)) {
   //How to echo column names and values here?
}

是否可以在while循环中遍历整个表时回显表的列名和值？

Answer 1

您可以使用foreach循环

$query = mysql_query("SELECT * FROM mytable");

while ($row = mysql_fetch_assoc($query)) {
     foreach($row as $key => $value) {
         print "$key = $value <br />";
     }
}

Answer 2

$query = mysql_query("SELECT * FROM mytable");

while ($row = mysql_fetch_assoc($query)) {
    print_r($row);
}

Answer 3

试试这个.. column_name与表中使用的名称相同

echo $row['column_name'];
