Split Nagios configuration into multiple files - file

Question

NagiosQL creates a file called servicetemplates.cfg.
For easier distribution of some selected templates I' d like to split any service definition into one seperate file.
Sample servicetemplates.cfg
define service {
name imap_service
use generic_service
check_command check_service_imap
register 0
}
define service {
name ldapserver_ldap_service
service_description LDAP
use generic_service
check_command check_service_ldap
icon_image ldapserver.png
register 0
}
What I like to have is some kind of parser, which create files like the "name" of the template, e. g. imap_service.cfg and ldapserver_ldap_service.cfg.
Every file have to include the whole definition (define service { ... } )

The following code is a solution for me, it might not be perfect as it expects a certain syntax of the Nagios object configuration.
The first parameter has to be the file name of the Nagios configuration file.
<?php
if (empty($argv[1])) {
echo "First parameter: File to Nagios object configuration\n";
exit(1);
}
$starttag=0;
$outfile='';
$outtext='';
$inputfile=$argv[1];
$cfgfile = file($inputfile) or exit(2);
foreach ($cfgfile as $line_num => $line) {
# $outtext will be reset if define ... { is found
$outtext.=$line;
# Start tag of a new section "define ... {"
if (preg_match("/.*define.*{/i", $line)) {
$starttag=1;
$outtext=$line;
}
# Split the line with name. The parameter after name is the later filename
if (preg_match("/name[\s]+[\w]+/", $line) && $starttag=1) {
$keywords=preg_split("/[\s]+/", $line);
$outfile=$keywords[2];
$outfile.=".cfg";
$outfile=str_replace(' ', '_', $outfile);
}
# End tag of a new section "}"
if (preg_match("/.*}/", $line) && $starttag=1) {
$starttag=0;
echo "Writing {$outfile}\n";
file_put_contents($outfile, $outtext);
}
}
echo "Read lines {$line_num} from {$inputfile}\n";
?>
