Question

open server

I've tried all the tricks in the link.

An example of the errors I want to see:

PHP Notice:  Trying to access array offset on value of type null in ...

Google gives no results.

php.ini

; ----------------------------
; Error reporting
; ----------------------------

display_errors              = "1"
display_startup_errors      = on
error_reporting              = E_ALL
error_log                    = "e:/other/os/ospanel/userdata/logs/PHP_7.3-x64_error.log"
;html_errors                 = on
;ignore_repeated_errors      = off
;ignore_repeated_source      = off
log_errors                   = on
;log_errors_max_len          = 1024
report_memleaks              = off
report_zend_debug            = off
;track_errors                = off
;windows.show_crt_warning    = off
;xmlrpc_errors               = off
;xmlrpc_error_number         = 0

Answer 1

You need to find php.ini for the desired version of php, and change error_reporting there .
Or change in your script via error_reporting() or ini_set()

Answer 2

You need to edit not the generated php.ini, but in the "e:/other/os/ospanel/userdata/config" folder, otherwise OpenServer will overwrite it on the next start.
