[snips-users] PHP Code to Read SNIPS Data Files

[Jerry Wilborn <jerry wilborn at corp.fast.net>]

If you ever wanted to read events directly from SNIPS data files with native
PHP code here is what you would use to do it.  I'm sure my code could stand
some improvements, I certainly welcome them if anyone has any.

#!/usr/local/bin/php -f
<?

if (! $file_handle = fopen("./data/ippingmon-output", "r")) die ("DIE: Could
not open file.\n");

$header = string_unpack($file_handle, "a*", 372);

while (!feof($file_handle)) {

        ++$current_event;

        $event[$current_event]['sender'] = string_unpack($file_handle, "a*",
16);
        if (!$event[$current_event]['sender']) {
unset($event[$current_event]); continue; }

        $event[$current_event]['device_name'] = string_unpack($file_handle,
"a*", 64);
        $event[$current_event]['device_addr'] = string_unpack($file_handle,
"a*", 128);
        $event[$current_event]['device_subaddr'] =
string_unpack($file_handle, "a*", 64);

        $event[$current_event]['var'] = string_unpack($file_handle, "a*",
64);
        $event[$current_event]['value'] = string_unpack($file_handle, "L",
4);
        $event[$current_event]['threshold'] = string_unpack($file_handle,
"L", 4);
        $event[$current_event]['var_units'] = string_unpack($file_handle,
"a*", 8);

        $event[$current_event]['severity'] = ord(fread($file_handle, 1));
        $event[$current_event]['loglevel'] = ord(fread($file_handle, 1));
        $event[$current_event]['state'] = ord(fread($file_handle, 1));
        $event[$current_event]['rating'] = ord(fread($file_handle, 1));

        $event[$current_event]['eventtime'] = string_unpack($file_handle,
"L", 4);
        $event[$current_event]['polltime'] = string_unpack($file_handle,
"L", 4);

        $event[$current_event]['op'] = string_unpack($file_handle, "L", 4);
        $event[$current_event]['id'] = string_unpack($file_handle, "L", 4);
}

var_dump($event);

function string_unpack ($file_handle, $method, $length) { return implode("",
unpack($method, fread($file_handle, $length))); }

?>
