PHP MySQL获取列名在遍历所有记录时

Question

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

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

是否可以在循环遍历while循环中的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

试试这个.. column_name是ü在表

echo $row['column_name']; 

Answer 3

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

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