二维数组根据指定多个字段排序/指定某个字段排序

二维数组根据指定某个字段排序

按照某一个字段排序

$sort = array(  
     'direction' => 'SORT_ASC', //排序顺序标志 SORT_DESC 降序；SORT_ASC 升序  
     'field'     => 'limit',       //需要排序的字段  
);  
$arrSort = array();  
foreach($arr AS $uniqid => $row){  
  foreach($row AS $key=>$value){  
      $arrSort[$key][$uniqid] = $value;  
  }  
}             
array_multisort($arrSort[$sort['field']], constant($sort['direction']), $arr); 
var_dump($arr);

二维数组根据指定多个字段排序

按照多字段排序

foreach ( $arr as $key => $row ){
	$field1[$key] = $row ['sort'];
    $field2[$key] = $row ['limit'];
    //$field3[$key] = $row ['order'];
}
array_multisort( $field1, SORT_ASC,$field2, SORT_ASC, $arr);
var_dump($arr);

模拟数据

$arr = [
    [
        'order'=>1,
        'limit'=>5,
        'sort'=>1
    ],
    [
        'order'=>3,
        'limit'=>4,
        'sort'=>1
    ],
    [
        'order'=>2,
        'limit'=>4,
        'sort'=>3
    ],
    [
        'order'=>4,
        'limit'=>1,
        'sort'=>10
    ]
];
