PHP MySQL获取列名称迭代所有记录

$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？

你可以使用foreach循环

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

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