@Wyck was right, ( well sorta 😛 ) you can set error logs but
1) You need to enable debugging
2) ini_set('log_errors', 1); or 0 for false
3) You need to set a log location via ini_set('error_log, $location)
Once you have that set you can then if need be test if said file exists via $location and turn off log_errors by setting its value to 0.
