PHP 二位数组按照下标排序
1.排序得内容
array(6) {
[0] => array(12) {
[0] => string(3) "160"
[1] => string(2) "30"
[2] => string(1) "1"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(1) "1"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[1] => array(12) {
[0] => string(3) "185"
[1] => string(2) "35"
[2] => string(1) "1"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(1) "1"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[2] => array(12) {
[0] => string(3) "175"
[1] => string(2) "33"
[2] => string(1) "1"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(1) "1"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[3] => array(12) {
[0] => string(3) "170"
[1] => string(2) "32"
[2] => string(2) "11"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(1) "1"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[4] => array(12) {
[0] => string(3) "165"
[1] => string(2) "31"
[2] => string(2) "11"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(2) "11"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[5] => array(12) {
[0] => string(3) "180"
[1] => string(2) "34"
[2] => string(1) "1"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(1) "1"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
}
按照里面的下标为1的排序
2 .方法:
$sort = array(
'direction' => 'SORT_ASC', //排序顺序标志 SORT_DESC 降序；SORT_ASC 升序
'field' => '1', //排序字段
);
$arrSort = array();
foreach($data_list AS $uniqid => $row){
foreach($row AS $key=>$value){
$arrSort[$key][$uniqid] = $value;
}
}
if($sort['direction']){
array_multisort($arrSort[$sort['field']], constant($sort['direction']), $data_list );
}
3. 结果:
array(6) {
[0] => array(12) {
[0] => string(3) "160"
[1] => string(2) "30"
[2] => string(1) "1"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(1) "1"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[1] => array(12) {
[0] => string(3) "165"
[1] => string(2) "31"
[2] => string(2) "11"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(2) "11"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[2] => array(12) {
[0] => string(3) "170"
[1] => string(2) "32"
[2] => string(2) "11"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(1) "1"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[3] => array(12) {
[0] => string(3) "175"
[1] => string(2) "33"
[2] => string(1) "1"
[3] => string(1) "1"
[4] => string(1) "1"
[5] => string(1) "1"
[6] => string(1) "1"
[7] => string(1) "1"
[8] => string(1) "1"
[9] => string(1) "1"
[10] => string(1) "1"
[11] => string(1) "1"
}
[4] => array(12) {
[0] => string(3) "180"
[1] => string(2) "34"
[2] => string(1) "1"
[3] => string(1) "1"
