Question

我从SOAP Web服务获得这样的对象：

object(stdClass)#2 (1) {
  ["tasks"]=>
  array(3) {
    [0]=>
    object(stdClass)#3 (9) {
      ["externalId"]=>
      string(0) ""
      ["name"]=>
      string(10) "Customer A"
      ["description"]=>
      string(0) ""
      ["bookable"]=>
      bool(true)
      ["billable"]=>
      bool(true)
      ["subtasks"]=>
      array(2) {
        [0]=>
        object(stdClass)#4 (9) {
          ["externalId"]=>
          string(1) "2"
          ["name"]=>
          string(5) "Job 1"

      string(0) ""
      ["customField3"]=>
      string(0) ""
    }
  }
}

我只需要一个愚蠢的函数来检查externalId的每个元素。

if( ["externalId"] != "")
{
   echo "value found! ".["externalId"]."<br>";
}

我尝试使用array_walk_recursive但该对象是数组和对象的混合。

比较[“子任务”] - 元素...... 还在SOAP调用中尝试了SOAP_SINGLE_ELEMENT_ARRAYS，没有区别。有一些“魔力”吗？我认为解决方案很简单，但还没有得到它： - （

请记住：递归级别没有限制 - 每个[“子任务”]都可以包含更多[“子任务”]。

谢谢

试试这个

<?php

/**
 * @param \stdClass $root
 *
 * @return array
 */
function externalIdentifiersFrom(\stdClass $root)
{
    static $properties = [
        'tasks',
        'subtasks',
    ];

    $identifiers = [];

    if (property_exists($root, 'externalId')
        && is_string($root->externalId)
        && '' !== trim($root->externalId)
    ) {
        $identifiers[] = $root->externalId;
    }

    foreach ($properties as $property) {
        if (property_exists($root, $property) && is_array($root->{$property})) {
            $objects = $root->{$property};

            foreach ($objects as $object) {
                if (!$object instanceof \stdClass) {
                    continue;
                }

                $identifiers = array_merge(
                    $identifiers,
                    externalIdentifiersFrom($object)
                );
            }
        }
    }

    return array_unique($identifiers);
}

var_dump(externalIdentifiersFrom($object));

PHP从数组+对象
