You can use file_get_content(), update the file content, then push the new data with file_put_content().
What we need is some comments where you need to insert new line :
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";
};
};
So you can catch your comments with PHP and add content after :
$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) ;
The code is quite simple here, catch the #External and put $newExternalZone after ! You can update and use data comming from POST,GET or other for newExternalZone.
I was able to do it using the below code. The code accepts arguments using PHP CLI and creates a new file with the values.
$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));
To execute the code callphp script.php --zone=my.new.external.zone --type=master --file=my.new.external.zone.db
