我有一个名为 的文件named.conf，它是BIND的配置文件。它有用大括号括起来的条目。我想使用 PHP 编辑并在内部和外部视图中输入新的区域条目。我怎样才能做到这一点。是否有可用于编辑此类配置文件的库？

view "internal"
{

match-clients { localnets; };
match-destinations { localnets; };
recursion yes;

include "/etc/named.root.hints";
    
zone "my.internal.zone" {
type master;
file "my.internal.zone.db";
};

};


view "external"
{

match-clients { !localnets; !localhost; };
match-destinations { !localnets; !localhost; };

recursion no;
    
include "/etc/named.root.hints";
    
zone "my.external.zone" {
type master;
file "my.external.zone.db";
};
};

您可以使用 file_get_content()，更新文件内容，然后使用 file_put_content() 推送新数据。

我们需要的是一些注释，您需要在其中插入新行：

view "internal"
{

match-clients { localnets; };
match-destinations { localnets; };
recursion yes;

include "/etc/named.root.hints";
    
#INTERNAL
zone "my.internal.zone" {
type master;
file "my.internal.zone.db";
};

};


view "external"
{

match-clients { !localnets; !localhost; };
match-destinations { !localnets; !localhost; };

recursion no;
    
include "/etc/named.root.hints";

#EXTERNAL
zone "my.external.zone" {
type master;
file "my.external.zone.db";
};
};

所以你可以用 PHP 捕捉你的评论并在之后添加内容：

$confText = file_get_contents('your_file_path') ;

$newExternalZone = PHP_EOL.
'zone "my.new.external.zone" {
type master;
file "my.new.external.zone.db";
};'.PHP_EOL ;

preg_replace("/(#EXTERNAL)/", "$1".$newExternalZone, $confText) ;

file_put_contents('your_file_path', $confText) ;

这里的代码很简单，抓住 #External 并把 $newExternalZone 放在后面！您可以更新和使用来自 POST、GET 或其他 newExternalZone 的数据。

我能够使用下面的代码来做到这一点。该代码使用 PHP CLI 接受参数并使用这些值创建一个新文件。

$file = file('named.conf');

$arg =  getopt("", array('zone:', 'type:', 'file:'));

$internal_end = 0;
$external_end = 0;
$flag = false;
$count = 0;
foreach ($file as $index => $line) {
    if (preg_match('/view\s*"internal"\s*{/i', $line) !== 1 && !$flag) {
        continue;
    }
    $flag = true;

    $ob =  substr_count($line, '{');
    $count += $ob;
    $cb =  substr_count($line, '}');
    $count -= $cb;
    if ($count == 0) {
        $internal_end = $index;
        break;
    }
}



array_splice($file, $internal_end, 0, array(
    "\n",
    "zone \"".$arg['zone']."\" {\n",
    "\ttype ".$arg['type'].";\n",
    "\tfile \"".$arg['file']."\";\n",
    "};\n",
    "\n"
));

$flag = false;
$count = 0;
foreach ($file as $index => $line) {
    if (preg_match('/view\s*"external"\s*{/i', $line) !== 1 && !$flag) {
        continue;
    }
    $flag = true;

    $ob =  substr_count($line, '{');
    $count += $ob;
    $cb =  substr_count($line, '}');
    $count -= $cb;
    if ($count == 0) {
        $external_end = $index;
        break;
    }
}


array_splice($file, $external_end, 0, array(
    "\n",
    "zone \"".$arg['zone']."\" {\n",
    "\ttype ".$arg['type'].";\n",
    "\tfile \"".$arg['file']."\";\n",
    "};\n",
    "\n"
));


file_put_contents('named_new.conf', implode('', $file));

执行代码调用php script.php --zone=my.new.external.zone --type=master --file=my.new.external.zone.db
