Mike brings up a good point about truncating excessively long
user-inputted strings when logging them.
I'm currently using something like this:
if (strlen($msg) > ProjectConstants::LOG_MESSAGE_MAX_LENGTH)
{
$msg = substr($msg, 0, ProjectConstants::LOG_MESSAGE_MAX_LENGTH);
$msg .= '...';
}
Any suggestions or ideas?
thanks,
Konstantin
