                )

            [4] => stdClass Object
                (
                    [BRANCH] => 01
                    [ZONE] => 03
                    [BLOCK] => 06
                    [MATL] => ST
                    [LENGTH] => 476.866
                )

            [5] => stdClass Object
                (
                    [BRANCH] => 01
                    [ZONE] => 04
                    [BLOCK] => 03
                    [MATL] => SCP
                    [LENGTH] => 64.875
                )

            [6] => stdClass Object
                (
                    [BRANCH] => 01
                    [ZONE] => 04
                    [BLOCK] => 03
                    [MATL] => ST
                    [LENGTH] => 44.888
                ) ....

我要在阵列ZONE =03来过滤数据。
结果谁能给的例子code做到这一点？
结果三江源。

I want to filter data in Array as ZONE = '03'.
Can anyone give the example code to do this?
Thankyou.

推荐答案

您可以利用array_filter的 http://php.net/manual/en/function.array-filter.php

You could make use of array_filter http://php.net/manual/en/function.array-filter.php

$input = (object)array(
  'success'=>1,
  'total'=>850,
   'data'=>array(
    (object)array('ZONE'=>'01'),
    (object)array('ZONE'=>'04'),
    (object)array('ZONE'=>'04'),
    (object)array('ZONE'=>'04'),
    (object)array('ZONE'=>'03'),
    (object)array('ZONE'=>'02')
  )
);

$output = array_filter($input->data,function($object){
  return ($object->ZONE == '04');
});

print_r($output);

array_filter由数组中的测试每个项目，并返回TRUE或FALSE的作品，在返回的括号标记是一个快捷方式返回一个布尔值。

array_filter works by testing each item in the array and returning TRUE or FALSE, the bracket notation on the return is a shortcut to returning a boolean value.
