如何在php中的数据库中每行只显示几个选项
[英]how to display only few options per line from database in php
问题描述
I am fetching data from the database and displaying it in the table.
我正在从数据库中获取数据并将其显示在表中。 I have applied a while loop before <tr> tag so it is showing each value in new line.我在<tr>标记之前应用了一个 while 循环，因此它在新行中显示每个值。
Now what i want is that it should show five values from database in each <tr> tag.现在我想要的是它应该在每个<tr>标签中显示来自数据库的五个值。 How can i do this ?我怎样才能做到这一点 ？
Here is my Code :这是我的代码：
<body>
<table border="2px;">
<tr>
<th>name</th>
</tr>
<?php
$sql="select * from tb_transport";
$query=mysql_query($sql);
while($row=mysql_fetch_array($query))
{
?>
<tr>
<td><?php echo $row["name"]; ?></td>
</tr>
<?php
} ?>
</table>
</body>

Try this:尝试这个：
You need to start on first record and close on last record of every row.您需要从第一条记录开始并在每行的最后一条记录上关闭。
<body>
<table border="2px;">
<tr>
<th>name</th>
</tr>
<?php
$sql="select * from tb_transport";
$query=mysql_query($sql);
$counter = 0;
while($row=mysql_fetch_array($query))
{
$counter++;
if($counter % 5 == 1)
{
?><tr><?php
}
?>
<td><?php echo $row["name"]; ?></td>
<?php
if($counter % 5 == 0)
{
?></tr><?php
}
} ?>
</table>
</body>

to show 5 records per line use显示每行使用的 5 条记录
if ($counter % 5 == 0) inside your while loop; if ($counter % 5 == 0)在你的 while 循环中；
<tr>
<th>name</th>
</tr>
<?php
$sql="select * from tb_transport";
$query=mysql_query($sql);
$counter = 1; // set counter to 1
while($row=mysql_fetch_array($query))
{
?>
<tr>
<td><?php
if ($counter % 5 == 0)
echo $row["name"];
$counter++;
?></td>
</tr>
<?php
} ?>
</table>

you can use counter variable,like.您可以使用计数器变量，例如。
<body>
<table border="2px;">
<tr>
<th>name</th>
</tr>
<?php
$count=5;
$sql="select * from tb_transport";
$query=mysql_query($sql);
while($row=mysql_fetch_array($query))
