I'm looking for a way to manipulate the results of a *nix ping query using PHP.

I'd like to be able to store the ping times in an array that I can manipulate for a script. The only examples I can find all just export the entire result to the screen, while I would like to just have them entered into an array.

Would anyone be able to help with a code snippet?

Thanks a ton.

lets see...

[php]
<?
$count=$HTTP_GET_VARS['count'];
$host=$HTTP_GET_VARS['host'];
$dumpedping=`ping -c $count $host`;
$pingarray=explode('\n',$dumpedping);
// so ping array now has each line... to find the time:
$index=0;
foreach($pingarray as $pingline) {
if($index>0) { // no data on first line
$time[$index]=ereg_replace(" .*","",ereg_replace(".*time=","",$pingline));
}
$index++;
}
// now time is an array with each time in it...
foreach($time as $data) {
echo("time: ".$data);
}
?>
[/php]


does that do what you need?

Yes, thanks...I didn't know you could dump the results of a system command into a variable. That makes it much easier!

enjoy the wonders of the backtick operator

Thanks for the suggestions, but the code as written above does not work for several reasons. The backtick operator only returns the last line of the output, and the foreach loop with the ereg_replace functions produces an error.

I rewrote it and it now works as well as being slighly more compact.

[php]
<?
$count =$HTTP_GET_VARS ['count'];
$host =$HTTP_GET_VARS ['host'];
exec("ping -c $count $host", $dumpedping);

foreach($dumpedping as $pingline) {
ereg("time=[0-9]+[.]{1}[0-9]+", $pingline, $time);
$pingTime[] = $time[0];
$time[0] = NULL;
}

for($i = 0; $i < count($pingTime); $i++) {
$value = $pingTime[$i];
echo "$value<br />";
}
?>
[/php]
