I probably covered this before, but I want to keep some log files of what is happening on various pages on a site. I could write to the php error log, but I look at those every morning and then erase them. I want something that sticks around but I don’t need a whole lot.
This solution works for me.
$fname = "./interesting_stuff.log";
$info = "Message";
$fp = fopen($fname, 'w');
fwrite ($fp, "$info" . "\r");
fclose($fp);
You’ll need to create the file and set the permissions so everyone can write to it before it will work.
