您可以使用PHP解析YAML文件，然后将其转换为数组，再使用数组操作函数将其转换为您需要的格式。具体步骤如下：

1. 读取a.yaml文件内容

$file = 'a.yaml';
$content = file_get_contents($file);

2. 解析YAML

$yaml = yaml_parse($content);

3. 将解析后的数组转换为您需要的格式

$netconf = array(
    'network' => array(
        'ethernets' => array(
            'fm1-mac3' => array(
                'addresses' => array(
                    $yaml['network']['ethernets']['fm1-mac3']['addresses'][0]
                ),
                'gateway4' => $yaml['network']['ethernets']['fm1-mac3']['gateway4'],
                'nameservers' => array(
                    'addresses' => array(
                        $yaml['network']['ethernets']['fm1-mac3']['nameservers']['addresses'][0]
                    )
                )
            ),
            'fm1-mac10' => array(
                'addresses' => array(
                    $yaml['network']['ethernets']['fm1-mac10'][0]['addresses'][0], 
                    $yaml['network']['ethernets']['fm1-mac10'][1]['addresses'][0]
                )
            )
        )
    )
);

// 将数组转换为YAML格式
$netconf_yaml = yaml_emit($netconf);

4. 将生成的netconf.yaml写入文件

file_put_contents('netconf.yaml', $netconf_yaml);
