I've changed my script to the following:
<?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);
print $line;
}
?>
And now get the following errors:
Warning: Wrong parameter count for fgets() in /var/www/html/logs2.php on
line 10
I get this over and over and over (like it's producing the error once per
line in the log file).
Thanks,
Scott
