B. 从Sopop HP开始的分类记录
原标题:Grouping records from while loop | PHP

我试图按其优先程度(例如)分类记录。

<>-> 优先程度:高

<>Records>

<>-> 优先程度:中

<>Records>

<>-> 优先程度:低——

<>Records>

与此类似,我如何在PHP这样做? 而按价值不变的优先权一栏(高=3、中=2、低=1)。 e.g. WHERE优先权 = 1

标签:Priority:[优先权水平]”必须放在关于其级别分类记录之上。

http://www.un.org。

<?php

while($row = mysql_fetch_array($result))
{
    echo  <h1>Priority Level:   . $row[ priority ] .  </h1> ;
    echo $row[ name ];
}

?>

同这部法典一样——

tags is the label which seperates records regarding their priority level.

最佳回答

如果你确定结果是按优先顺序排列的,那么情况就好像这样:

$priority = null;
while($row = mysql_fetch_array($result))
{
    if( $row[ priority ] != $priority )
    {
        echo  <h1>Priority Level:   . $row[ priority ] .  </h1> ;
        $priority = $row[ priority ];
    }
    echo $row[ name ];
}

换言之,你在<代码>优先顺序变量中保持当前优先水平的轨道。 然后检验在<代码>if中是否改变了优先权。 如果是的话,<代码>echo将优先处理目前各行的优先顺序。

如果按优先顺序排列,这只是按预期(真正分类)进行。 换言之,如果不同的优先事项不分散在结果上。

如果你使用我的智慧,那么你为什么不使用亚洲开发银行的指令能力?

SELECT *
FROM items
ORDER BY priority DESC
