Trying to find php_error_log

Hi

Using Terminal, where can I find php_error_log?

I found another post on the forum that suggested using

find / -name php_error_log

I got a permission denied message. Then I remembered I need to put sudo before any commands, so I tried

sudo find / -name php_error_log

Terminal listed lots of files, but still output the permission denied message.

I’ve also tried looking at my info.php file, but the only reference I could find was error_log, that just says no value

Any help would be much appciated.
