Array 
(
    [0] => Array

      [14] => 2016-11-04 
      [cdate] => 2016-11-04 
     ) 

) 

我想只获得列值。但为什么我得到数组索引的值？

Answer 1

首先我想说mysql函数已被弃用。所以现在继续使用mysqli或PDO更适合mysqldatabse的功能。

没有任何参数mysql_fetch_array函数将输出DB记录在index和column-name这两种格式。

要获得数据column-name只有你应该已经通过第二个参数“MYSQL_ASSOC”在mysql_fetch_array功能或代替你可以使用mysql_fetch_assoc功能以及。

$result = mysql_fetch_assoc($mysql_query);
