答案 0 :(得分：2)
您可以循环使用索引，并将第二个数组的属性添加到第一个：
for ($index = 0; $index < count($array1); $index++) {
$array1[$index]->mysummary = $array2[$index]->mysummary;
}
答案 1 :(得分：2)
您可以结合使用array_map和array_merge来达到相同的目的，而不必依赖于数组的静态键。
$result = array_map(function($a,$b){
return array_merge(isset($a) ? $a : array(), isset($b) ? $b : array());
},$a1,$a2);
Demo。
答案 2 :(得分：2)
foreach ($array1 as $key => $value) {
$array1[$key]->mysummary = $array2[$key]->mysummary;
}
echo '<pre>';print_r($array1);
