Find and store directives in http.conf

[Asheeown]

So I am making a linux migration script and my third step is to transfer all the VirtualHost directives and the NameVirtualHost to the new machine.

 

For the NameVirtualHost assignment I need to get any and all lines that look like this:

NameVirtualHost 192.168.1.170:80

And save them in an array so I can add them to the new server, there are usually only one of those entries but multiples can occur

 

For the VirtualHost directives I'll give an example below

<VirtualHost 192.168.1.170:80>

# Created on Aug 20, 2009

ServerAdmin webmaster@test.com

DocumentRoot /home/Test/htdocs

ServerName www.test.com

ServerAlias test.com

AddHandler server-parsed htm html shtml

AccessFileName .htaccess

CustomLog /home/Test/Logs/access_log combined

<Directory />

AllowOverride All

</Directory>

<Directory /home/Test/htdocs>

Options Indexes

Options +Includes

</Directory>

ScriptAlias /cgi-bin/ /home/Test/cgi-bin/

</VirtualHost>

 

I figured since the VirtualHost directive is always the same, but the IP may be different it shouldn't be too hard.  However, I never got into regex and I can't figure out how to get these things and store them in variable for later use.

Given the nature in which it's being used, I think you'd be fine with something as simple as this:

 

preg_match_all('#<NameVirtualHost (.*?)>#', $source, $vhost_matches);

[Asheeown]

preg_match_all('#<NameVirtualHost (.*?)>#', $Contents, $vhost_matches);

 

Produces two empty arrays within $vhost_matches

 

If I take away the # symbols in the pattern I get three values $vhost_matches[0] $vhost_matches[1] $vhost_matches[2] but all they have in them is "NameVirtualHost"

[Asheeown]

I started working off what you gave me and I got it:

 

<?php
preg_match_all('/NameVirtualHost [^\*].*:.*\r/', $Contents, $vhost_matches);
?>

 

Produces just what I need.

 

Now I just have to figure out the virtualhosts

[Adam]

Just so you know it doesn't match which regex delimiter you use. People have their own preference, I just seem to think I have to escape less using hash.

 

And.. well if it works, just wrap the part you want to match in brackets:

 

preg_match_all('/NameVirtualHost ([^\*].*:.*)\r/', $Contents, $vhost_matches);

[Asheeown]

That works great.  Now for my VirtualHosts one, I made one, and like I said, I'm horrible at this.

 

<?php
preg_match_all('/\<VirtualHost [^\*].*?\>.*\<\/VirtualHost\>/s', $Contents, $vhost_matches);
?>

 

Only problem is it takes away every directive, starting with <VirtualHost> they just don't show up in the output.  There are other directives inside <VirtualHost> such as:

<Directory>

<Location>

And things of that nature, any idea of why that is happening?

 

[Adam]

Try this:

 

<?php
preg_match_all('/<VirtualHost (.*?)>(.*?)<\/VirtualHost>/s', $Contents, $vhost_matches);
?>

[Asheeown]

Still excludes all directives inside.

Have you checked the source?

Have you checked the source?

 

What's in the desired output is in the file.  It's excluding everything wrapped in < >
