如何从print_r中获取数组值($object)

ob_start();
print_r($object, true);
$result = ob_get_clean();

$result_array = explode("\n", $result);
$final_result = array();

foreach ($result_array as $item) {
    $item = trim($item);
    if ($item != '') {
        $item_array = explode("=>", $item);
        $key = trim($item_array[0]);
        $value = trim($item_array[1]);
        $final_result[$key] = $value;
    }
}

// 输出获取到的数组值
foreach ($final_result as $key => $value) {
    echo "键：" . $key . "，值：" . $value . "<br>";
}
