Truncate?

[joink]

Hi I am trying to write a php script for creating a graphical network map to determine outages for a setup I have... It's been a while that Ive worked with PHP and could use some help, Im sure if I search long enough I'll figure out everything I need.  Maybe you can help save me some time?

 

What I have now is a text based network map, which follows.  There is some formatting.. Indents and bullets next to each line.

br-ths.inds.th_ind_s, 30/30 beats, 4 ms/4 ms/4 ms, UP
br-thind.ths.south.th, 30/30 beats, 5 ms/5 ms/5 ms, UP
br-core.prov.core.th, 30/30 beats, 4 ms/4 ms/4 ms, UP
rtr.core.th, 30/30 beats, 54 ms/15 ms/15 ms, UP
sw1.core.th, 30/30 beats, 4 ms/1 ms/1 ms, UP
br-frm.core.th, 30/30 beats, 4 ms/3 ms/3 ms, UP
br-core.main.farmersburg, 30/30 beats, 4 ms/4 ms/4 ms, UP
br-datalabel_1313.core.th, 30/30 beats, 1 ms/0 ms/0 ms, UP
br-core.1313.th, 30/30 beats, 3 ms/2 ms/2 ms, UP
sw.1313.th, 30/30 beats, 4 ms/4 ms/4 ms, UP
br-core.datalabel.core.th, 30/30 beats, 1 ms/1 ms/1 ms, UP
datalabel-router.core.th, 30/30 beats, 3 ms/2 ms/4 ms, UP
br-13thST.core.th, 30/30 beats, 1 ms/1 ms/1 ms, UP
br-core.13thST.th, 30/30 beats, 2 ms/2 ms/2 ms, UP
rtr.13thST.th, 30/30 beats, 2 ms/3 ms/5 ms, UP
sw.13thST.th, 30/30 beats, 10 ms/7 ms/7 ms, UP

 

Can I call this file and create a couple variables based on each line?  I think truncating is what I need... where I would create a variable up to the first comma and another variable following the last comma.

 

So for first line (after posted update time/date)

 

$br-ths.inds.th_ind_s = 'UP'

or something like $br-ths.inds.th_ind_s = $status

 

 

In the end I will have a network map with colors to represent if each device is up or down (red or green) however the indented (child) devices below the parent devices, if they are down and the parent is up I will have display yellow (if less than half the child devices are down) if more than half is down, the color will be orange.

 

Hope this makes sense, and hope you can help.

 

Thanks

Thanks for that!

 

What I have now:

<?php

$file_handle = fopen("networkmap.asp", "rb");

while (!feof($file_handle) ) {
$line_of_text = fgets($file_handle);

// Strip HTML formatting
$content = strip_tags($line_of_text);

$strip_content = substr($content, 34);
list($router,$metric,$ping,$status)=explode(",",$strip_content);

}

fclose($file_handle);

echo $router;
echo $metric;
echo $ping;
echo $status;

?>

 

Is there an easier way than a whole bunch of if/and statements with this setup?  Can I identify each exploded result as a variable automatically?

 

if ($router=='br-ths.inds.th_ind_s' && $status='UP') {

$stat_img = 'green.png';

} else {

 

and so forth...

 

Is there an easier way to identify each exploded variable? I may have as many as 100 or more to monitor... And lastly how do I associate each variable to each line.  Where $status for one router is not the same $status for another line item/router?

<?php

$file = file("networkmap.asp");

foreach(file('networkmap.asp') as $value) {

// Strip HTML formatting
$content = strip_tags($value);

$strip_content = substr($content, 34);
list($router,$metric,$ping,$status)=explode(",",$strip_content);
echo $router;
echo $metric;
echo $ping;
echo ($status == 'UP') ? '<img src="green.png" alt="up" />' : '<img src="red.png" alt="down" />';
echo '<hr />';
}
?>

[teamatomic]

$file = file("test.txt",FILE_IGNORE_NEW_LINES|FILE_SKIP_EMPTY_LINES);
array_shift($file);
foreach($file as $value)
{
$content = strip_tags($value);
     //	$content=trim($content);
list($router,$metric,$ping,$status)=explode(",",$content);
$status=trim($status);
$img = ($status == 'UP') ? '<img src="green.png" alt="up" />' : '<img src="red.png" alt="down" />';
echo "$router $img<hr />";
}
