PHP 搜索过滤器按字母顺序对结果排序

Question

我正在开发一个带有搜索功能的小型网络目录。我在 Joomla 中使用 Eshop 软件。有制造商筛选功能，但这些结果不是按字母顺序显示的。

我四处寻找解决方案，但我无法让它工作。这是代码：

<?php
if (!empty($filterData['manufacturer_ids'])){
    $manufacturerIds = $filterData['manufacturer_ids'];
}
else{
    $manufacturerIds = array();
}

foreach ($manufacturers as $manufacturer){?>
    <li>
        <label class="checkbox">
            <input class="manufacturer" onclick="eshop_ajax_products_filter('manufacturer');" type="checkbox" name="manufacturer_ids[]" value="<?php echo $manufacturer->manufacturer_id; ?>" <?php if (in_array($manufacturer->manufacturer_id, $manufacturerIds)) echo 'checked="checked"'; ?>>
            <?php echo $manufacturer->manufacturer_name; ?><span class="badge badge-info"><?php echo $manufacturer->number_products;?></span>
        </label>
    </li>
<?php }?>

谁能帮帮我？

您可以使用 sort 函数，我建议使用 SORT_STRING 可选参数为您提供以下内容。

$manufacturers = sort($manufacturers, SORT_STRING);

This function sorts an array. Elements will be arranged from lowest to highest when this function has completed.

...

SORT_STRING - compare items as strings

编辑：

确认数据结构后，这是一个对象数组，需要自定义排序功能。因此，您应该使用 usort().

This function will sort an array by its values using a user-supplied comparison function. If the array you wish to sort needs to be sorted by some non-trivial criteria, you should use this function.

因此，您首先定义比较 manufacturer_name 属性.

字符串的函数

function cmp($a, $b)
{
    return strcmp($a->manufacturer_name, $b->manufacturer_name);
}

usort($manufacturers , "cmp");
