基本上我正在尝试像这样分组我的数组:
Shopping
Amazon
Social
Amoeblo
American express
使用以下PHP代码:
<?php
echo '<ul id="list"><h2 class="searchresults"></h2>';
foreach($records as $catval) {
$sitechar = $catval->site_category;
echo '<h3 id="disappear">'. strtoupper($sitechar) .'</h3>';
echo '<li class="siteli"><a href="#" class="add">';
echo '<p id="text-site">'.$catval->site_name. '</p></a>';
echo '</li>';
}
echo '</ul>';
?>
但是我的价值只有如下。
Shopping
Amazon
Social
Amoeblo
Social
American express
我没有得到用于此的确切PHP排序。

我会创建一个新数组,其中类别为带有网站的数组的键。
<?php
$arr = array();
// First create multidimensional array with categories as keys for site arrays
foreach($records as $catval) {
$sitechar = $catval->site_category;
if (!array_key_exists($sitechar, $arr)) {
// Set new array for a category if it does not exist
$arr[$sitechar] = array();
}
// Add site to category
$arr[$sitechar][] = array(
"name"=>$catval->site_name,
"image"=>$catval->site_img
);
}
// Then iterate the new array of categories
echo ("<ul>");
foreach($arr as $category => $sites) {
echo("<h3>" . $site_category "</h3>");
// Iterate array of sites
foreach($sites as $site) {
echo("<li>" . $site["name"] . "-" , $site["image"] . "</li>");
}
}
echo("</ul>");
?>

你可以使用foreach和ksort
来做到这一点让$ your_array成为您上面提到的数组
$res_array = array();
foreach($your_array as $val){
$res_array[$val->site_category][] = $val->site_name;
}
ksort($res_array);
print_r($res_array);
或者在php中搜索multisort来解决你的问题:)

$tmp = null;
echo '<ul id="list"><h2 class="searchresults"></h2>';
foreach($records as $catval) {
$myHtml = makeHtml($catval,$tmp);
echo $myHtml;
$tmp = $catval->site_category;
}
echo '</ul>';
function makeHtml($catval,$tmp){
if($tmp != $catval->site_category){ $html .= '<h3 id="disappear">'. strtoupper($catval->site_category) .'</h3>';}
$html .='<li class="siteli"><a href="#" class="add"><p id="text-site">'.$catval->site_name. '</p></a></li>';
return $html;
}
