我是一个PHP新手，在这个问题上挣扎了一段时间，所以任何帮助都会很感激。
使用bootstrap我有一个无序的列表，我想用它来显示mysql的记录。
我可以在几个不同的方式显示记录没有问题，但似乎我不能得到这个工作与我选择的引导布局。主要问题是试图将递增的数字附加到以下内容:
<?php
include 'dbconnect.php';
$info = mysql_query("SELECT firstname, lastname, postalcode, date, phone, timeframe, city, available FROM (SELECT * FROM `custdata` ORDER BY id DESC LIMIT 0 , 3) t ORDER BY id ASC") or die(mysql_error());
$count=1;
while ($info = mysql_fetch_array($newusers)) {
echo"
<div class='panel panel-default'>
<div class='panel-heading'>
<h4 class='panel-title'>
<a data-toggle='collapse' data-parent='#accordion_leads' href='#collapse".$count."'>";
echo $info['firstname']." ".$info['lastname']."<div style= float:right>". $info['postalcode'].""</div>";
</a></h4></div>";
echo '<div id="collapse'.$count.'" class="panel-collapse collapse">';
echo "<div class="panel-body">";
echo
"<ul class=list-group style=font-size:13px>
<li class=list-group-item> <strong>Location:</strong>", $info['city'],
"</li><li class=list-group-item><strong>Date:</strong>", $info['date'],
"</li><li class=list-group-item><strong>Phone:</strong>", $info['phone'],
"</li><li class=list-group-item> <strong>Timeframe:</strong>", $info['timeframe'],
"</li><li class=list-group-item> <strong>Availability:</strong>", $info['available'],"</li>
</ul></div></div>";
$count ++; } ?>
试试这个，复制我的代码并替换你的代码，你就完成了
<?php
$count=1;
while ($info = mysql_fetch_array($newusers)) {
echo"
<div class='panel panel-default'>
<div class='panel-heading'>
<h4 class='panel-title'>
<a data-toggle='collapse' data-parent='#accordion_leads' href='#collapse".$count."'>";
echo $info['firstname']." ".$info['lastname']."<div style= float:right>". $info['postalcode'].""</div>";
</a></h4></div>";
echo '<div id="collapse'.$count.'" class="panel-collapse collapse">';
$count ++;
}
?>
试试
<?php
$count=0;
while ($info = mysql_fetch_array($newusers))
{ ?>
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion_leads" href="#collapse<?php echo $count; ?>">
<?php echo $info['firstname'].", ".$info['lastname']; ?>
<div style='float:right'><?php echo ", ".$info['postalcode'] ?></div>
</a>
</h4>
</div>
<div id="collapse<?php echo $count; ?>" class="panel-collapse collapse">
<?php $count ++; } ?>
