Sorting an associative array in PHP
Sorting a multidimensional array in PHP?
我有一个系统允许将订单分配给送货司机。以下来源列出了当前可用的分销商列表,以及他们与客户的距离:
$franchise_a_status = array();
$franchise_a_status[] = array('id' => '', 'text' => 'Please Select');
$franchise_query = mysql_query("select franchise_id, franchise_surname, franchise_firstname, franchise_postcode, franchise_availability from " . TABLE_FRANCHISE . " where franchise_availability=1");
$origin = $cInfo->entry_postcode;
while ($franchise = mysql_fetch_array($franchise_query)) {
$destination = $franchise['franchise_postcode'];
$json = file_get_contents("http://maps.googleapis.com/maps/api/distancematrix/json?origins=$origin&destinations=$destination&mode=driving&sensor=false&units=imperial");
$result = json_decode($json, true);
$distance = $result['rows'][0]['elements'][0]['distance']['text'];
$franchise_a_status[] = array('id' => $franchise['franchise_id'],
'text' => $franchise['franchise_surname']. ' ' .$franchise['franchise_firstname'].' '.'('.$distance.')');
}
列表使用下拉菜单显示:
array('text' => tep_draw_pull_down_menu('franchise_id',$franchise_a_status));
我需要按照最短距离到最高距离的顺序对数组进行排序。
