我试图在MySQL数据库中获取多行,但它只获取第一个条目!
$data = mysql_query("SELECT * FROM twitter_tbl")
while($info = mysql_fetch_array($data))
{
$desc = $info['description'];
$screen_name1 = $info['screen_name'];
$final_oauth_token = $info['final_oauth_token'];
$final_oauth_token_secret = $info['final_oauth_token_secret'];
);
所以我只得到一行,但我需要获得多行,因为每一行都有其唯一的screen_name和描述。
我不知道自己哪里出错了。

更正此代码:
$data = mysql_query("SELECT * FROM twitter_tbl");
while($info = mysql_fetch_array($data))
{
echo $desc = $info['description'];
echo $screen_name1 = $info['screen_name'];
echo $final_oauth_token = $info['final_oauth_token'];
echo $final_oauth_token_secret = $info['final_oauth_token_secret'];
}

虽然语句包含在{}而不是{);
中编辑:
$data = mysql_query("SELECT * FROM twitter_tbl")
while($info = mysql_fetch_array($data))
{
Echo $desc = $info['description'];
Echo $screen_name1 = $info['screen_name'];
Echo $final_oauth_token = $info['final_oauth_token'];
Echo $final_oauth_token_secret = $info['final_oauth_token_secret'];
}

您只需将其放在一个可在您的网页上显示结果的容器中
试试这个:
echo "<table>";
$data = mysql_query("SELECT * FROM twitter_tbl");
while($info = mysql_fetch_array($data))
{
$desc = $info['description'];
$screen_name1 = $info['screen_name'];
$final_oauth_token = $info['final_oauth_token'];
$final_oauth_token_secret = $info['final_oauth_token_secret'];
echo "
<tr>
<td>".$desc."</td>
<td>".$screen_name1."</td>
<td>".$final_oauth_token."</td>
<td>".$final_oauth_token_secret."</td>
</tr>";
}
echo "</table>";

将数据添加到数组中。 你的目标是什么? (存储数据?echo?)
CODE:
$data = mysql_query("SELECT * FROM twitter_tbl");
if($data && mysql_num_rows($data) > 0)
{
while($info = mysql_fetch_array($data))
{
$desc[$i] = $info['description'];
$screen_name1[$i] = $info['screen_name'];
$final_oauth_token[$i] = $info['final_oauth_token'];
$final_oauth_token_secret[$i] = $info['final_oauth_token_secret'];
++$i;
}
unset($i, $info, $data);
}
或者喜欢Echo模式
CODE:
$data = mysql_query("SELECT * FROM twitter_tbl");
if($data && mysql_num_rows($data) > 0)
{
$x = "
<table>
<tr>
<th>
desc
</th>
<th>
screen_name
</th>
<th>
oauth Token
</th>
<th>
secret oauth Token
</th>
</tr>";
//Warning it's eat a lot of memory
while($info = mysql_fetch_array($data))
{
$x .= "
<tr>
<td>
{$info['description']}
</td>
<td>
{$info['screen_name']}
</td>
<td>
{$info['final_oauth_token']}
</td>
<td>
{$info['final_oauth_token_secret']}
</td>
</tr>";
}
$x = "
</table>";
echo $x;
unset($info, $data, $x);
}
