The following works perfectly:
<?php
$file ="/var/log/radius.log";
$fp = popen("/usr/bin/tail -$limit $file", 'r');
if (! $fp ) {
echo 'unable to pipe command';
}
while (!feof($fp) ) {
$line = fgets($fp, 4096);
print $line."<br>";
}
?>
I've tried bumping up the 4096 to a higher number because it currently only
shows me 10 lines - I'd like to see about 30. No matter what I change the
number to, it still only shows 10 lines. What do I need to do to get more
that the 10 lines?
Thanks,
Scott
