从PHP修改smb.conf?

I need to add/remove SAMBA shares through PHP or via SSH (ssh link from PHP).

So far the only solution I've found is a class for primitively handling the file, which I haven't got very much faith in in terms of reliability. (http://www.phpclasses.org/package/1546-PHP-Parse-and-recreate-the-Samba-smb-conf-file.html)

Could you recommend a way to do it?

    Can't find something useful, so I would recommend a likewise simplistic approach. Instead of finding a full-fledged INI parser, it's advisable to work in append-mostly mode. A simple regex would be sufficient to replace existing [share] sections without harming the rest of the smb.conf file.

    And you can use the testparm utility to probe for correctness before overwriting the real file.

    define("SMB_CONF", "/etc/samba/smb.conf");
    
    function add_share($section, $options) {
    
        // read old data
        #$old = parse_ini_file(SMB_CONF);
        $conf = file_get_contents(SMB_CONF);
    
        // merge new settings
        #if (isset($old[$section])) {
        #    $options = array_merge($old[$section], $options);
        #}
    
        // remove old share section, if it exists
        preg_replace("/^\[$section\]\s*
    (^(?!\[).*
    )+/m", "", $conf);
    
        // write out new ini file
        $conf .= "
    
    [$section]
    ";
        foreach ($options as $key=>$value) {
            $conf .= "$key = $value
    ";
        }
        $tmp = tempnam("/tmp/", "SMB");
        file_put_contents($tmp, $conf);
    
        // copy if it is syntactically correct
        if (strstr(`testparm -s $tmp 2>&1`, "OK")) {
            rename($tmp, SMB_CONF);
        }
    }
    

    Updated Okay, parse_ini_file does not work in either case. It trips over the smb.conf style. So you can only completely replace existing entries, not update them.

    Zend Framework's Zend_Config setup might be useful as it's able to read/write ini files.

    Zend_Config_Writer
