根据条件筛选多维数组（多条件）

php怎么多维数组筛选
例如有一个二维数组
array(3) {
[0] => array(3) {
["PILE_ID"] => string(3) "222"
["PILE_NAME"] => string(3) "121"
["PILE_STATION"] => string(1) "4"
}
[1] => array(3) {
["PILE_ID"] => string(16) "YS12345678912345"
["PILE_NAME"] => string(7) "测试2"
["PILE_STATION"] => string(1) "1"
}
[2] => array(3) {
["PILE_ID"] => string(2) "12"
["PILE_NAME"] => string(3) "121"
["PILE_STATION"] => string(1) "1"
}
}
现在知道前端传过来的 ["PILE_STATION"]=='1'
处理结果为
array(2) {
[0] => array(3) {
["PILE_ID"] => string(16) "YS12345678912345"
["PILE_NAME"] => string(7) "测试2"
["PILE_STATION"] => string(1) "1"
}
[1] => array(3) {
["PILE_ID"] => string(2) "12"
["PILE_NAME"] => string(3) "121"
["PILE_STATION"] => string(1) "1"
}
}

还有，实现了要怎么实现多条件筛选，前面的PILE_STATION=='1'还知道PILE_ID=='12'要怎么做得到结果
array(1) {
[0] => array(3) {
["PILE_ID"] => string(2) "12"
["PILE_NAME"] => string(3) "121"
["PILE_STATION"] => string(1) "1"
}
}

最后还有如果什么都没传过来，即不知道条件，默认结果是原来的数组，即结果为
array(3) {
[0] => array(3) {
["PILE_ID"] => string(3) "222"
["PILE_NAME"] => string(3) "121"
["PILE_STATION"] => string(1) "4"
}
[1] => array(3) {
["PILE_ID"] => string(16) "YS12345678912345"
["PILE_NAME"] => string(7) "测试2"
["PILE_STATION"] => string(1) "1"
}
[2] => array(3) {
["PILE_ID"] => string(2) "12"
["PILE_NAME"] => string(3) "121"
["PILE_STATION"] => string(1) "1"
}
}

你这是写好的数组？还是从数据库中读出来的？

$arr = array(
  0 => array(
    "PILE_ID" => "222",
    "PILE_NAME" => "121",
    "PILE_STATION" => "4"
  ),
  1 => array(
    "PILE_ID" => "YS12345678912345",
    "PILE_NAME" => "测试2",
    "PILE_STATION" => "1"
  ),
  2 => array(
    "PILE_ID" => "12",
    "PILE_NAME" => "121",
    "PILE_STATION" => "1"
  )
);
var_dump(array_filter($arr,function($v){return ($v['PILE_STATION']=='1')?true:false;}));
echo '<br/>';
var_dump(array_filter($arr,function($v){return ($v['PILE_STATION']=='1' && $v['PILE_ID']=='12')?true:false;}));
echo '<br/>';
