问题描述

我使用下面的代码来显示图片&

 < fieldset> 
< h1> A< / h1>
< ul>
<?php foreach($ records as $ key){?>
< li class =siteli> < a href =#class =add>
< div id =site-icon>< img src =<?php echo $ key-> site_img;?> width =16height =>< / div>
< p id =text-site> <?php echo $ key-> site_name; ?>< / p为H.
< / li>
<?php}?>
< / ul>
< / fieldset>

现在我试图按照字母顺序将A,B,C等作为标题进行分组。

例子,

  A 
Amazon
Aol
Aol Mail

B
Bing
Bogger


解决方案

您可以使用排序数组。在你的情况下,我会选择



现在使用前面的信件显示链接:

 <?php 
$ records = ['aaaaa','aaaa2','bbb','bbb2','Dddd'];
$ lastChar ='';
sort($ records,SORT_STRING | SORT_FLAG_CASE); //标志是需要的。没有`Ddd`就会在`bbb`之前。
//可从版本5.4获得。如果你有一个更早的版本(4 +),你可以尝试natcasesort()

foreach($记录为$ val){
$ char = $ val [0]; ($ char
$ b $ if($ char!== $ lastChar){
if($ lastChar!=='')
echo'< br>';

echo strtoupper($ char)。'< br>'; //打印A / B / C等
$ lastChar = $ char;
}

echo $ val。'< br>';
}
?>

这会输出类似于

<$ p $ a
aaaa2
aaaaa

b
bbb
bbb2

D
dddd

请注意,C缺失,因为没有以C开头的单词。


I'm using below code to display Image & Name of webisites form database.

<fieldset>
    <h1>A</h1>
    <ul>
        <?php foreach ($records as $key) { ?>
        <li class="siteli"> <a href="#" class="add">
            <div id="site-icon"><img src="<?php echo $key->site_img; ?>" width="16" height=""></div>
            <p id="text-site"> <?php echo $key->site_name; ?></p>
        </li>
        <?php } ?>
    </ul>
</fieldset>

Now I'm trying to group this results alphabetically by adding A, B, C etc as title.

Example,

A
Amazon
Aol
Aol Mail

B
Bing
Bogger
解决方案

You can use array sorting to sort the array. In your case I would choose sort()

Now to show the links with a preceding Letter I would use:

<?php
$records = ['Aaaaa', 'Aaaa2', 'bbb', 'bbb2', 'Dddd'];
$lastChar = '';
sort($records, SORT_STRING | SORT_FLAG_CASE); //the flags are needed. Without the `Ddd` will come before `bbb`.
//Available from version 5.4. If you have an earlier version (4+) you can try natcasesort()

foreach($records as $val) {
  $char = $val[0]; //first char

  if ($char !== $lastChar) {
    if ($lastChar !== '')
      echo '<br>';

    echo strtoupper($char).'<br>'; //print A / B / C etc
    $lastChar = $char;
  }

 echo $val.'<br>';
}
?>

This will output something like

A
Aaaa2
Aaaaa

B
bbb
bbb2

D
Dddd

Notice that the C is missing, because there are no words starting with C.
