如何在while循环PHP中拆分返回的结果

Question

我正在开发一个应用程序，在这个应用程序中，我需要返回两行的结果，并在其中创建一个标记来显示VS图标(这是竞争)。在某个阶段，我需要分割结果，对吗？如何实现这一目标，

结果应该是

<div class='hero_comp'>

        <div class='hero_comp_img'><img src='images/$picture' alt='$name' width='200' height='200'/></div>    

        <div class='hero_comp_txt'>$reason</div>

        <div class='hero_comp_btn'><form action='' method='post'><input type='hidden' name='id' value='$id'/><button type='submit' class='btn btn-primary border-radius-zero' name='vote'><i class='fa fa-thumbs-up'></i> Vote for me</button></form></div>

<div class='vs'></div>


<div class='hero_comp'>

        <div class='hero_comp_img'><img src='images/$picture' alt='$name' width='200' height='200'/></div>    

        <div class='hero_comp_txt'>$reason</div>

        <div class='hero_comp_btn'><form action='' method='post'><input type='hidden' name='id' value='$id'/><button type='submit' class='btn btn-primary border-radius-zero' name='vote'><i class='fa fa-thumbs-up'></i> Vote for me</button></form></div>

这就是我迄今所做的

$select_comp=mysql_query("SELECT * FROM nominate WHERE accepted='1' ORDER BY id DESC");
if (mysql_num_rows($select_comp) >=2 ) {

    while ($row=mysql_fetch_array($select_comp)) {

    $picture=$row['picture'];
    $reason=$row['reason'];
    $id=$row['id'];
    $name=$row['name'];

    echo"

    <div class='hero_comp'>

    <div class='hero_comp_img'><img src='images/$picture' alt='$name' width='200' height='200'/></div>    

    <div class='hero_comp_txt'>$reason</div>

    <div class='hero_comp_btn'><form action='' method='post'><input type='hidden' name='id' value='$id'/><button type='submit' class='btn btn-primary border-radius-zero' name='vote'><i class='fa fa-thumbs-up'></i> Vote for me</button></form></div>

    </div>

    ";

    }
}

如果您想要完成的是循环遍历结果，并显示结果1和结果2，然后转到下一个配对，您可以在循环中添加一个计数器，以确定您在模式中的位置。

$count=1;
$select_comp=mysql_query("SELECT * FROM nominate WHERE accepted='1' ORDER BY id DESC");
if (mysql_num_rows($select_comp) >=2 ) {

    while ($row=mysql_fetch_array($select_comp)) {

    $picture=$row['picture'];
    $reason=$row['reason'];
    $id=$row['id'];
    $name=$row['name'];

    echo"

    <div class='hero_comp'>

    <div class='hero_comp_img'><img src='images/$picture' alt='$name' width='200' height='200'/></div>    

    <div class='hero_comp_txt'>$reason</div>

    <div class='hero_comp_btn'><form action='' method='post'><input type='hidden' name='id' value='$id'/><button type='submit' class='btn btn-primary border-radius-zero' name='vote'><i class='fa fa-thumbs-up'></i> Vote for me</button></form></div>

    </div>

    ";

        if ($count==1) {

            /* Display VS Button since the 1st result has been posted, increase count to 2 for next loop */

            $count=2;

        } elseif ($count==2) {

            /* If you want to insert something to separate the Result 1 VS Result 2 just echoed, go for it here, otherwise we set the count back to 1. */

            $count=1;

        }
    }
}

这将迫使1vs2，3vs4，5vs6从您的表中进行排序，因为您是按ID排序的。如果您想指定一个不同的配对，还有其他几种方法可以做到。

将结果添加到两个不同的数组中。

在while循环之后，您可以执行两个预见(http://www.php.net/manual/en/control-structures.foreach.php)操作，并以这种方式拆分数据。

例如：$select_comp = mysql_query("SELECT * FROM *FROM=‘1’ORDER BY id DESC")；if (mysql_num_rows($select_comp) >= 2) {

    $rows = array();
    while ($row=mysql_fetch_array($select_comp)) {
        $rows[] = $row;
    }

    // Present the data as you wish here
    // The first row will be $rows[0] and the seconds $rows[1]
}
